one of these days ETA 1: day 1; ETA2 tested; ETA#3 tested some more; ETA4 new scope & load

I'm going to assemble the 6x45 upper I got in mind.

got all the parts sitting in a box ready to go; just got to get around to it; course the donor upper is the model 1 hbar carbine upper with the 1:8 shaw barrel I rarely shoot anymore and the factory installed ff tube on it has been loctited on so its going to take some heat to break it loose.

but when it's done it's going to be a 6x45 ar stoner 20" ss hbar mounted on the model 1 a3 upper, model 1 bcg, model 1 ff tube, model 1 railed gb, dpms rifle length gt and ar stoner 9/16x24 flash hider.

got the dies in yesterday so I figured I'd play around a bit this evening & ran a few new winchester cases through (going to run the rest of them through the rt1200 to uniform the length of the 223cases first before resizing/forming/necking them up to the 6mm since I don't have a 6x45 trim die (machineshop dillon 223 trim die special ));

made up a dummy round and it dropped in the chamber just fine; simple enough so far; load data says this round will sling a 75gr bullet to 2950fps, a 85gr to 2800fps, 90gr to 2750fps and a 100gr to 2600fps but that's for a 24" pressure barrel so load developement as always is in order for my ar and a chrono will tell the tale; figure I'm going to have to see how much of a cut it's going to take since I got to seat to a col of 2.25" max to fit in a mag and thats going to eat up a bit of powder space.

I had one of the 6mmTCU (only slightly different from the 6x45-6/223) years past assembled on a rem 788 action with a 24" med/hvy barrel that shot like mad; it shot a 87gr bullet to iircc 2900fps without undue pressure issues but the bullet was seated out farther iirc it was around 2.4"+; damned if I can remember but for some dumbassed reason I traded it off and have wanted another every since and figured the ar the perfect platform for this caliber but hadn't found a affordable barrel in stock until recently;

now ar stoner and black hole weaponry barrels are both very affordable and in stock.

this ought to make a nice little low recoil woods rifle for deer/hogs/squirrels whatever

UPDATE #2 2-6-2012:

tested 50 rounds today, the rifle function fine; put the tubbs 4oz carrier weight in and the rifle has the wolff extra power buffer spring and heavy car buffer; the scope or pepr mount took a shit though but then that's why we all got buis installed on our rifles.

loaded up ten rounds per charge weight from 23gr to 25grs all dropped with a hornaday powder measure with weight set up/verified in a lyman 505 with my typical measure set up/verify. in virgin re-sized/formed 6x45 cases from Winchester 223 brass (trimmed to 1.740" before sizing up); cci 400 primer, speer 100gr btsp "deep curl" bullets and ramshot tac powder; these loads worked in my rifle but may blow your's the fuck up so do you own load workup in your rifle.

didn't chrono any loads as I wanted to make sure the rifle functioned as I've read some of these 6x45 barrels have a undersized gas port from the factory to let the customer custom tailor to their particular load(s) and to give me an idea of what load I wanted to work around.

the scope and/or mount issue came to light during the first three rounds of the 23gr load; fucker hit 2' right at 80 yards, I did a major adjustment and it only moved the next impact over approx 6", I cranked on the turret some more and ran out of adjustment; it did move the impact over another approx 12" and hit the edge of the target. I fired the other 7 rounds an got an approx 11/4" group; primers looked fine, no flat spots, all brass landed a heap approx 6' away at 3 o'clock.

next up was the 23.5gr load; first round hit approx 2' to the right again, the next round approx 8" to the left and the third round went kicked up dust approx 6' to the left of the target; so I pulled the scope off, flipped up the buis and started shooting; they were dead center approx 5" low poa; quick adjustment got them centerish; didn't bother trying to measure groups with load; primers again looked fine and cases landed in same approx area as the 23gr load.

onto the 24gr load; approx 3" group, three primers had slight flat spots, the other seven looked fine; cases landed same approx area as the other loads.

24.5gr load; approx 3" group for ten rounds; five primers had moderate flat spots, the other five looked fine; cases landed in same approx area as the other loads.

25gr load; approx 13/4" group for ten rounds (either I was on the ball or this is a damn good load); all primers had moderate to severe flat spots; cases landed in same approx area as the other loads.

all in all besides the flat spotted primers the cases looked good, no blown or severely cratered primers, no dents on the shoulders, no ejector swiping on the case heads or other noticeable pressure signs although I didn't mic the case heads to see if they expanded.

it isn't a tell all load development but gives me an idea of where/what load to work around for the 100gr bullets; got some 85 and 87grainers on order and one of those will most likely be my hunting bullet; but testing will tell.

going to have to chrono loads to check es/sd and velocity; first I'm going to have to get the scope/mount issue worked out cause I can't shoot ittybitty groups with open sights; can't hardly shoot them using a scope so I need all the help I can get; had both on the rifle for several years without issue; the mount was tight, so I'm thinking it's a scope issue but we'll see when I get a chance to mess with it again.

damn case tumbler took a shit today also; so I got approx 250 cases sitting in it covered in case lube and corncob.

ETA #3 2-9-12:

mounted a old bushnell 4x32 in a one piece mount I had laying around; it's cheap cast aluminum but should work just fine for this since it has been solid enough in the past.

loaded up 30 of the 24gr tac loads; used these as a base to sight in a different scope; they shot pretty damn good; 10 shot groups were right around 11/2" @80 yards;

tested 10 rounds each of the following loads:

23gr of aa2230; rifled cycled fine, accuracy approx 11/2" for 5 rounds, 3/4" for the next group; primers looked great; brass dropped at 3 oclock in the same pile.

23.5grs aa2230; rifled cycled fine, accuracy right at 1" for both 5 rounds groups; primers looked great; brass dropped at 3 oclock in the same pile.

24grs aa2230; rifled cycled fine, accuracy right at 11/4" for 5 rounds; 4 rounds were under 1/2"; 3/4" for the next group; primers slightly flat in center, rounded on edges; brass dropped at 3 oclock in the same pile.

going to do some more developement with this powder; looked as if I might find a bit more in it; but I'm going to have to break out the chrono to see how well velocity is; the the aa2230 had a bit more blast than what the tac had; charge weights are simular; but curious as to velocities are for both.

so far this rifle has shot pretty well and about as consistant as I can shoot it; once I find a load it likes the best it may become my new favorite deer woods gun.


ETA: #4 2-28-12:

installed a 4.5x14x40 nikon in a set of med high burris rings I had laying around; it really needs a cantilever mount as the scope sits back approx 1" over the stock but they'll have to work for now.

loaded up some 87gr vmax over aa2230 in winchester cases with cci400; they shot just fine dumping all the cases in a pile at approx 5 oclock; primers were slightly flat but edges were still rounded; I think if I seat the bullet a bit farther out it'll resolve the flattening issue, but this will necessitate removing the poly tip from the bullet and I'm sure that'll affect downrange performance a bit because its reducing the bullet's BC, but at the ranges I'm planning on using this cartridge I don't see it as that big of an issue.

the one group I got to shoot I put 10 rounds into approx 1 1/4" at 80 yards, but they hit approx 12" to the right and 6" high so as soon as I get the chance in good light I need to get it sighted in and then I'll shoot some 5 shot groups to see what it does for an average.

plus I need to chrono the fps to see what kind of velocity I'm getting with the 87s and 100; if I can get 2500+ fps out of the 100 I will be satisfied with it for deer/hogs in the woods; I'm going to buy a couple of boxes of the 80gr & 90gr speer deep curls and see how well they do also.

Sounds like a nice new toy! Heres some load data that might help ya find the load youre wantin...i tried makin it a hyperlink but my phone and the website arent playin nicely..... http://buckammo.com/Images/6x45_loaddata_1_1.pdf

ETA: the comp I'm using won't open it; I got a "book" from a link posted in a thread in the reloading forum that has a lot of 6x45 load with various powders.

My phone will d/l and open that file but i cant make hyperlinks in the forum....lol.

dumb smart phone i take it?

so smart it could even make it through a mud puddle

Not without a friend who has 4WD and a snatch strap.

makes me think somebodies speaking of panties everytime I hear it.

You've been hanging out in too many strip bars.

hadn't been in a strip club in a very long time

Of course

Mungo dumb....Bart smart

Got it assembled this afternoon;

fuckmefunny a 20 minute barrel swap took the better part of two and a half hours; the Goddamned china's best vice gave up the ghost right after I broke the birdcage loose on the 223 barrel.

so had to make a trip to town for another, bought a irwin this time so hopefully I get a couple of decades or more out of it; back to the house, mounted it to the bench and 10 minutes later had the old barrel off and the new one on with the ff tube, gb and flashhider and the upper was completely assembled.

now I got to work up some loads and give it a whirl.

soon as I get a cam I'll shoot a few pics and post one up; it don't look any different from a 20" ss hbar in a FF tube except it says 6x45 1:8 5R

Got any stats on the velocity out of a 20" barrel?

85gr are in the 2800fps range +/-50fps,
90gr are 2700fps+/-50fps; and
100gr are 2600fps+/-50fps.

I got some 100gr speer sp's on hand, but the 85 to 90grainers are probably the best bet going for deer sized hunting.

going to have to hit the local shops for a box of 85's, 87's and 90's to see which is best, but hell the 100grs may do well and I stick with them.

For deer I'd probably go with the heaviest bullet I could find.
I'm not much on 243 calibers for deer anyway.
Of course, I said that about 223 but dropped some deer with one year before last.
But knowing you Brother L, you could drop them with a 22.
Those glowing eyes make a good target in the spotlight.

Throw away those magazines and get some C-Products mags or somethin....I load my 6.8 AR out to 2.295 and thats Sierra Pro Hunters lead tips rubbin the front of the mag! 2.25 is rediculously short, from my experiences with'em. The magazine you use will determine the OAL. I have 2-25 round mags, 2-5round mags and 6-15-round mags for my 6.8 and they're all C products mags. The PRi mags let ya load the 6.8 out a lil further so you can put a tad more powder in them n have a lil more velocity yet have the same-ish pressure.

You can figure about 50fps per 2 inches of barrel length when it comes to AR's from 16" to 20"

it's all about bullet placement; you shoot an animal in a bad/non vital not immediately lethal spot and it runs off to die a lingering painfull death; you shoot it in a vital immediately lethal spot and it dies quickly.

Is that English? I don't think you could word that to be any more redundant and confusing

It's plain to read. You shoot the SOB where it will drop immediately because you don't want to work your ass off looking for it.

I'm Shawnee, english wasn't as strongly emphasized in my household as it was proabably yours; besides the above statement was written for Dan, english isn't his best subject either, he's got to sound the words out to read it, then reread it several more times before he comprehends it so if I write it all confusing like it'll take him days or weeks to understand it

maybe it wasn't written so confusing

I'm a pretty poor shot so I don't shoot for the head; got to be the shoulder shot unless they've got a cigarette pack or a playing card on the side of their head, then I shoot pretty much dead on.

Poor fella. It's a miracle his post count is that high.

Dan's just a whore, post and otherwise

Bite me. Both of you!

I ain't falling for that.

if you do happen to fall, make sure you fall backward so you can keep your eyes on Dan at all times, if you fall forward you liable to end up with a monkey on your back right quick

You'd be the one to watch. The only thing you ever turned down was a 88 year old man.
And you turned him face down.

hell yeah I had to turn him face down, you can't bury vampires face up or they dig out quickly; you bury them face down and they keep digging until they reach china

Man, that college ejumacation IS working!

With you riding them all the way, I'm sure.

Picture. Ndenway

ever hear a vampire squeal like a pig?
