RMR 69 gr OTMs

[markm]

I received my order of 500 RMR 75 gr and plan to load some next week.

Interested in your results. Good price on the N140. I wanted to get some to try, but we've been running N135 for now.

It will be a few weeks before I get a chance to load and test but will definitely post results. Several things I am looking at to keep things in perspective.

1. I’ve never loaded .223 before and have minimal experience loading .308

2. I’ll be using two rifles to check accuracy, an AR (SOLGW lower with BCM Upper) and a brand new Ruger American Gen 2 20” I just ordered.

3. I plan to load 3 powder charger and shoot 5 round groups at 50 and 100 yards.

I’ll see what happens…

Gotcha. I think someone here shot them and accuracy wasn't impressive.

So don't be afraid to post if they don't shoot.

I think I am going to settle on 24.2 gr of Ramshot Tac at an OAL of 2.23 for the 69s. I know RMR said to load them short and between these and the Hornady 68s, they both shot better loaded short. The 75s shot well at 23-23.5 but the SD was so wide. Settling on 24 gr of tac and 2.235 with the 75s. Having only been able to test at 50 yards so far.

I will post pics when I get to the range. I promise honest results.

I read through RMR's forum, and there was a post from one of their Mods that stated that their favorite load is 24.6 grains of TAC with an overall length of 2.245" and LC brass and an unknown primer. I chrono'd this load today, using CCI 41s and they averaged 2742 for 5 shots, with an SD of 7.9. The barrel was a 16" CHF FN.

Right after Thanksgiving, I shot a group to confirm a decent zero with this load through a LaRue 16" Match Grade Upper while standing at a tripod. My first three were touching in a perfect triangle, so I stopped. It wasn't a legitimate group, considering I wasn't really trying and I was just timing the break as the reticle intersected the initial hole through my wobble, but it was funny how my first "group" with them was sub 1/4 MOA.

I'll be testing them from a bench soon.

Got 30 of the 75s loaded up to test. 10 TAC CCI41, 10 H322/Wolf SRM, and 10 VVN135/Wolf SRM.

Plan to shoot 5 each in two bolt guns with different twists. And hopefully at 200 yards if the wind is acceptable. Otherwise just out to 100.

Hope they work out. I loaded 15 each with 24.0, 24.5, and 25.0 grains VVN140.

I plan on seeing how they perform in my AR’s and my new bolt gun. I should buy some quality factory ammo to compare against…may have to do that. Almost all my ammo is 55 or 62 grain stuff.

Thanks for doing this, Mark.

No problem. We're addicted to testing stuff. I may shoot them against the 69 gr RMRs if we think it's relevant. Praying for calm wind today.
