So I put my 308s to the test today, I found that the 43.5Gr VArget load did the best so far....... 168 Gr SMK 2.8 OAL, Federal Brass. Group shot @ 100 yrds, I managed to f up real good and pull the forth shot right,
so about 1.2 Moa? 
and If I didnt mess up about .7 Moa Outa a gun THEY told me couldnt shoot around 1Moa

really?..... well I will re measure, I was under the assumption that it was edge to edge minus the diameter of the boolit, Btw it is a Mossberg ATR100 in 308, Let the hatin begin Lol, this was the best group so the consistency of the gun is kinda shady , as the barrel warmed up after about 5 shots the groups spread.... alot and the poi shifted farther left as well
Edit second was around .6moa not .7 |

Good job man.
I found my best .308 load to be 43.5 gr of varget too (wth a 165 SST). Shooting out of a supressed AR10 W/22" cut factory barrel, I got several ,<1/2" 4 round groups, 2 were only .33'! (100m from a bipod). Anyway, What legnth barrel do you have? -I thought you might be interested to know that my average velocity with the load was 2652, with an ES of 21 and an SD of 7 over all the groups. I worked my way up to 44.0 gr of Varget and started around 38 or so IIRC, but found 43.5 was definatly the sweet spot for me too, by both group size and ES/SD measurements. It's actually the only load / round that I have been able to beat the performance of FGMM with. I don't know what your powder measure set up is like, but I found when I straped a $6 walmart fish tank airpump to the measure on my LnL that my group sizes tightened up and that my throws with Varget REALLY tightened up! -JTR P.S.: You mentioned measuring edge to edge minus bullet dia.. That is actually the same as measuring center to center, but is easier than trying to figure out were the exact center is, so yes you are doing it right. (Half the dia of the bullet is outside of the center on one, the other half on the other, that's why you're subtracting the bullet dia. when measuring from the outsides. |
| cool It has a 22" 1and10 barrel, I didnt use a measure on these i just used a Lee scoop and trickled the last few 10ths, everyone is within 1/10th if not 5/100s grain, Now i just need a Savage 10 and i will be set up for even better shooting and less gun cool down time |
| Thanks guys, I only wish the rifle/Me could should groups like that every time, Mayby the bull barrel Savage Ive got my eye on will help, but as far as the Mossy goes, More than good for them deer this fall, now to get some A-Max,s and try them, Anybody use them to hunt small deer, havnt seen any monster buck were I hunt so.......Im sure the Amax expand better than the SMks, even though its not a hunting bullet just going by reveiws on midway. |
| Supposeably the SST's are better for hunting than the A-max, but I don't really know that for sure. One thing is if you do try the 165 sst, it get's set deaper than the 168BTHP or A-max, even though they take the same charge. -I tried working the sst's out from Hornady's suggested 2.750" COL to 2.800' like a BTHP or A-max would get and found a decrease in accuracy and increase in pressure, as well as significantly increased deviations. -I actually ended up having an lower average velocity, higher max velocity, and some blown primers @ 2.800" with the SST's and a 43.5 gr Varget load! What is realy interesting is the SST is a longer bullet too, so it really compresses the powder more. Anyway, I had such good luck with the SST's I haven't tried the A-max in .308 (used to shoot bthp's), even though I use the A-max in .223. I would be interested in hearing your results when/if you try the A-max out with your load. (BTW, the barrel in mine is a 1:11.25"). |
| Good deal, I will probably get some A-maxs next time i make an order to try them,but will keep the ssts in mind as well, for target shooting it really dosent mater on deadlyness anyway, i have some 180gr Hornady Spbts that will most defintly mutalate bambi so those can always be my hunting load. Thanks again |
Yeah i loaded from 42-44 in .5s for my first batch of 50, and the 44s made it hard to open my bolt so i ended up pulling 8 of the 10 i did @ 44, i know the 42s sucked bad they shot low and left when i got into the 43 and 43.5 they shot where i was previously zeroed,(that dont mean nothing) but just a bit left as you can see on the target, I dont think there was any crosswind that day but dont remember........ I had a good four shot group going on another target with the 43s as well, but it was full of 22lr holes by the end of the session, damn smallbores spitting out their little bullets by the hundreds
Edit: added pic well here it is bout the same .966 minus 308 .65"

Thanks again I use the AMAX and the SST, go AMAX for hunting. The SST does far and above more damage than is necessary. The bullet pretty much shatters once it hits thick bone, but its very effective. I load the 150 SST for my M1 Garand over 47.5 grains of IMR4895 for deer or any varmint critters unlucky enough to cross my path. The AMAX, well lets just say I'm a fanboy of them, specifically the 178AMAX. They don't seem to break up as easily as the SST, and they tend to group better for me also. Try the 155 or 168 AMAX for a light recoiling, hard hitting hunting round, For deer with a bolt action .308, the 155 AMAX over 46 grains of RL15 is.... Thor's Hammer. |
