Itching to try the 185 Jugs in the .308 for the first time. I never used MR2000 before and does anyone have any good results with that powder in the .308? Any loads you like to share, of course I'll work up. I know Varget is my go to powder, just thought that MR2000 will work nice with the heavies.

MR2000 , 185 Jugs in .308
- Thread starter TackDriver2
- Start date
185 juggs , 47-48 gns 2000mr, lapua brass and winchester brass . 18" 12 twist Lothar barrel 2625 fps . Lake city and Fed brass star alot lower in charge. 45.5 +
Yes i have seen him talk about using that powder in his 20" Ax to gain velocity. Start low and work up .
Loaded up 3 round charges in .3 increments from 45 -47.2 grains in Lapua brass / Fed210M, will see results soon round robin style at 200
My load is 46gr of 2000MR with the 185 at 2.830 and it's 2700fps out of my 20" AX
I've been shooting the 185 Hybrid with 47.2 grains 2000MR (Lapua brass) thru my 26" Bartlein 5R ten twist for about two years now. Last time I chrono'd I was 2820 FPS and needed 8.7 mils to get to 1,000 yards from 100 yard zero.
Did you see any signs of pressure? I have a GA Precision Crusader with a Bartlien 26 inch as well, but I have the 11:25 twist.
I actually went as high as 47.5 grains without issues. Have seen no issues with excess pressure but that was my rifle, not anyone else's.
Going to give 2000MR a try. I worked with the 185's and Varget and never could get them to shoot in my TRG. Odd because its been a very forgiving rifle for most other loads.
I have been heating good things about this powder. I'm having pressure issues in my AR10 and hope this might let me get the velocity up above 2500 fps. Any one use this in .223/5.56? I want something I can use in both.
How does 2000MR do with temperature changes (temp sensitivity)? I am loading up for a match down here in Georgia, but the match is in Wyoming and will be 20-60 degrees colder.
Fps is great and while doing load dev for 185 jus and 200.20x bullets for my f class 30" barrel..ive noticed fps changed from 84° to 64° so i asked some pro f class shooters and some confirmed that they went backto vargert so not to worry about temp..BUT these are f class shooter strictly..tact shoiting wont make you missed that silhouette
Thanks for the feedback. Did you record your velocities for the different temps? And how was your SD’s in relation (ie if there was a total 20fps difference, buy your SD is 15, it makes it more difficult to find more concrete answers).
