@dryflash3 or @AeroE - would it be possible to toggle this thread on the RMR 69gr bullets to not go into archives?
We have a few threads going on these bullets, but this one seems to be the critical mass for collecting data from multiple posters. |

Ok, I tested some A2520 with these and I’ll get the results posted soon.
Does anyone have any powders they would like me to test with these rmr bullets? I have few powders to choose from. My primers are pretty limited but I’ll do what I can. |

Varget at 24.6-24.9gr. If they shoot, they’ll likely shoot with that charge range.

I’ve done Varget in this thread already

The 26.0 load had pressure signs. Western powder says 25.8 is max 5.56 load for 2520.

Standard deviations were much to large for my liking and the groups I was getting wasn’t much different.
Which could be my poor shooting Edit to add pic Attached File |

I tested these the other day with W748, once fired LC brass and CCI41 primers. Started at 25.4 gr and went up to 25.8 gr with no pressure signs. Best accuracy at 25.6-25.8 with SD's below 10 on both. 25.6gr @ 2879. 25.8gr @ 2922 with 20" barrel. 10 round groups.

I’ve previously shot test loads using CFE223 and RE15. Today I loaded 15 with each powder at the charge weight that showed the best accuracy in each powder.
Attached File Attached File I fired these 15 round groups with a round robin manner. Pretty clear that RE15 performs better than CFE223 with the 69 gr RMR bullet in this particular barrel. |

Agreed, lots of people have success with it. But I’ve never found accuracy for cfe223
Great looking 15 shot group with RE-15 |

I managed to grab 8# of TAC from our Brownell’s overlords.
I will be trying TAC under some 69 gr RMR bullets next. I’m happy with the Re15 accuracy, but I have to throw each charge, weigh it and usually trickle up a small extra amount of powder to stay at the consistency of charge I want. I’m hoping TAC gives similar accuracy but will let me simply throw charges with my Uniflow. |

First nice day in over 3wks here, tried out my new-to-me Intellidropper this am to load:
ZQI/MKE once fired 556 brass trimmed to 1.750, swaged primer pocket, no flash hole work Primed with F205GM Varget 24.5, 24.7, 25.0, 25.3 RMR 3GH seated to 2.260" -.004", +0.0" Fed from a Lancer mag into a 18" Shilen srp barrel, fired through CE chrony, 75f ~50% humidity. I shot a few sighters from the 24.5 loadings on a lower target, so the subsequent groups are deviations from that zero. My hold was center red for all groups. Results (5 shot groups) 24.5gr - 0.59moa - 2862(avgfps) - SD 20 24.7gr - 0.72moa - 2843 - SD 23 25.0gr - 0.75moa - 2884 - SD 28 25.3gr - 1.05moa - 2910 - SD 22 Going to try to add some pics here... https://imgur.com/a/5Qg7h1Y https://ibb.co/VqRwhMq ^^ I shoot my test loads clockwise from top left, center target hits were just screwing around. https://ibb.co/dWRPXcD https://ibb.co/C0pcKjs https://ibb.co/9np6VkH https://ibb.co/zRN726s Sorry, I'm trying to add more pics but imgur is not working well today. I have screenshots from the chrony app as well. I want to play with more test loads in the 24.5-25 range, but Im thinking of trying Shifty's 2.230" seating depth with the 24.5 first. @SuperJlarge |

Although I have not had the chance to shoot the RMR's yet, I've had super results with 23.7 TAC in 3 rifles with both Sierra and Nosler 69's. Not the fastest by any means but it pokes tiny groups in everything I shoot. I expect equal results with the RMR's.

Oddly my best results with this bullet, as well as the wholely dissimilar 75gr Speer TMJ, and the 77gr SMK are all at the same powder charge; 21.4gr of AR Comp. I had started at 22.5gr of AR Comp based on previous luck with Alliant load data, but my super short throated Bergara AR barrel was blowing primers at this charge weight (none of my other guns have problems with this ammo). I really cannot explain the 21.4gr thing for 3 bullets that are so different.
Velocity was pretty pitiful at around 2850fps from a 24" barrel. I should mention that these 5,000 bullets I have are from their original batch several years ago before their press broke. |
|
|
Shot my ladders.
The second one went kinda meh as it was a very frustrating range day from issues unrelated to the bullet and I think I started rushing and pulled several shots that should have made good groups. Which is okay because 3/4 of the first ladders groups were under moa with the best at roughly 0.6 moa. Will measure and post better pictures tomorrow but hopefully this is a repeatable group. I was only aiming for 1moa for bulk longer range plinking ammo. Doing a 5x5rd group test tomorrow to verify comprehensive accuracy. This is with the calipers zeroed on a .224 projectile so its the center to center measurement. Attached File |

I only weighed charges while setting up each step in the ladder. Also, I didn't say the Re15 shot like crap, just that I didn't get the results I was looking for. So anyway... 1 vote for Re15... |

I shot some 69 gr RMR bullets over TAC this morning. All of these loads are using LC brass, CCI#41 primers and seared at 2.26”
Attached File Attached File Attached File Attached File A couple of called flyers in the results, due to range conditions. The rifle line was full and I had shooters on both sides using brakes. I’ll load 20 at 24.6 gr and shoot a more statistically significant group. |

Something I thought I'd toss out as a note, since I've run into it a few times now - the range at my club is in a small valley and has an odd swirling breeze on a good day and a stiff one more often than not. We use H style 2x4 target bases and furring strip+cardboard backers. I had to start bringing weights along for my precision trips because the target moves back and forth up to 6" in the base due to the breeze. Took me a few trips to catch on, and it can really throw a good group off.

I'm loading more at 24.5 gr, 24.7 and 24.9 gr of TAC. I'll shoot all of these to see if I can fine tune a TAC load. However, loading about 30 in total finished off my first batch of 500.
I placed an order for 1,000 more of these 69 gr bullets. |

I’m too dumb to post pics 7 shots went into one bug hole. I pulled the other 3.
Kicker is it was at 50 yards. I’m shooting left handed as my right eye has macular, The trigger is also-heavier than I like. I figure part of the group is shooter error. Only problem I see with 4166 is charges need to be individually weighed. |

View Quote I have a 24" barrel that has a stupidly short throat that is causing me lots of consternation, but the one upside to it is that I am getting the same velocities and accuracy of many of the guys running 18" MK12 type guns. For example, in an 18" barrel MK262 tends to run 2760fps with a very stout load, but it provides incredible accuracy. I can handload the same bullet with a much lighter powder charge and achieve identical accuracy at the same velocity. Blessing or curse; has yet to be decided. |
