Long Range Heavy Bullet Rifle Help?

[quote/] have you tried H1000? I’m getting an es of 12 with a 10 shot group with 210’s and H1000,cci250’s

I know H1000 will likely have lower es, & better accuracy - But  I'm trying to get that last 50-75 fps.   Trying to get over it.  I know once I test h1000 I will say wth did I waste 300 rounds trying to get that last 75 fps with RL33?  Hoping for speed and accuracy......

Maybe retumbo?  I never got re 33 or re25 to run well in my 300wm.  H1000 and re22, imr7828 those were golden.

I am sure that you already tried this.... But switching from FED 215 to CCI250 dropped my ES down by a lot.  I have some 215 Bergers that i sent back for testing.  They ogive was .028 thou longer and put me seated into the doughnut of the brass.  Not cool.  Threw me for a big loop but could tell something was up when i seated them..

I chrono'd the rounds today and had a decent ES and SD.  I did have a few outliers that were 20-30 or so FPS slower.  I also noticed the slower rounds were not near as accurate.  If I get less than 2930 fps accuracy dropped off.  I think I am at the bottom of my node so I am working up my powder charge by .1 grain increments from here. 

I was able to re-create a sub 1/2" 5 shot group.  I took the last 5 shots and shot a 1-1.25" group at 200 yards which was slightly dissapointing.  I will keep working it and see what comes of it.  I may have to drop to a 180-185 grain bullet as the twist is 1:12 so I am pushing heavies to their max to try and stablize them.

Its just subjective but I found the CCI's did work better unless it was cold or loads were slightly compressed. ? I had a couple hangfires so I switched to 215's and never had a problem since.  I think the gentler ignition of the cci250 works better until it doesn't I guess ??
