new shooter; eveyone
Just so all can know I loaded some 230 OTM (.719BC) up at some of the higher loads like new shooter; at the 3rd reload on the brass I has a case separation down near the web area ( I think that is correct)...basically at the bottom of the case about 1/8 inch up. You start to see a funny distortion in the brass with these high pressures. Berger list 88.something as being in the 90 something percent load density. Doing some rough math calc 89.4 was 100% LD is what I figured. With this I was able to get 2970-2980 fps in a stock sendero 26inch barrel. My drops proved out to be running closer to 3016 fps at 4800 ft.. Basically all guns and chambers are different but be very careful with that load and check for all signs of brass failure from high pressure loads. I now load 89.3 grains and I am .070 off the lans which leaves me single feeding but it shot almost a 1 hole group at 200yrds. The guys at EOL shoot the target 230 VLD bullet which I believe is like .743BC. I think you can buy them off there web sight. HSM is loading them up. Looks like thy have no issue with dropping some game with them.

300 RUM (Remington 700 SS action, Krieger SS 27" barrel)
Berger 230-grain OTM
Federal 215M primers
COAL ~ 3.8"
97.1 grains LRT @ 2,950 fps
97.2 grains LRT @ 3,000 fps

The 97.1-grain load yielded a 0.192" three-shot group at 100 yards.

QuickLoad told me I could go up to 99 grains or so. I stopped my ladder at 97.4 grains of LRT. (I have a pretty tight chamber.)
