Anyone loaded the RMR 69gr bullets? (Page 6 of 6)
Pfft!, a mere 198. Is that all?  That was some great shooting, no doubt about it. My comment was about group size, nothing more. Several others have 2+ MOA groups, myself included. I'll post photos once the testing is done, perhaps next week. It is forecast to be ~95 degrees at the range next week. Not too bad, really, I've been up there on work parties when it was 105. |

Fresh barrels really help. Old (high round count) barrels sometimes will put up a very good group. But old barrels can be very ammunition sensitive. The barrel in that ShotMarker screenshot was early in its life. |

I have not tried to optimize RMR 69s, but I find that I can very lazily throw something together and get 1-1.5 MOA without any effort. Here's my current batch of blasting ammo: Mixed brass; no trimming 24.5 - 24.6 grains Ramshot Xterminator 2.230" OAL Crimped Shot this yesterday @ 100 yards. Solid square is 1 inch. I've gotten similar results using H335 and SW Tac Rifle. I'm happy with that for 14 - 15 cents w/ zero effort involved. However, Midsouth has 77s and 75s for 20 cents that I just started playing with this week.

69 gr RMR HPBT bullet 12 rounds fired at 100 yards, No correction for wind was attempted (multiple mph wind shifts evident in photo) 24.0 gr TAC, WSR primer, R-P cases Top two fliers are 100% my fault (called). Group is 0.63 MOA (worst case spread, C-C)  While not the RMR bullet, I bought these "factory seconds" in an attempt to keep costs down. I'm showing them as a visual and quantitative reference (a benchmark). IMO, the RMR bullet is a superior approach at cost cutting, as long as you are okay with its ballistic limitations (it is only 69 gr). 77 gr Factory Seconds (Powder Valley) 10 rounds fired at 100 yards, No correction for wind was attempted 23.5 gr TAC, WSR primer, PSD cases No fliers (called or otherwise) Group is 1.13 MOA (worst case spread, C-C)

My first attempt used 23.5 because that's what I use for my 75's. I simply upped that to 24.0 because W_E_G does it - no "science" (no optimization); just do it. It was easy (and fun). |

@snackle I use a 10.5 sbr with thermal so not the top velocity but it's handy and light important when you are carrying 2-3 rifles to a stand messing around. I've take 12 so far with it anywhere from 80 to 150lb range pigs. 10 drt 2 that ran off easy to tell they were hit that's not a bad number with an sbr 223. I still haven't gotten any non pass through so i could try and capture a bullet. 223 exit holes just aren't impressive even with gold dot's.  Big sounder 69 rmr 223 thermal pig hog hunt |
