I know u said not your rifle. But in general Gents, I have recently won some competitions in ELR 1 and 2 mile with my .375 CT, setup is as follows: VICTRIX factory .375 CT THRONE rifle 1:8 twist 38inch Bartlein barrel Running necked down .408 peterson brass VVN570 propellant Hornady ATIPs 390gr TPL is 4.310 inches Load is 124.5gr Average temperature in SA (this is where we shoot) is 30 degrees C. 3009 fps is the average (after the barrel has set, took about 130 shots) and before that it was 2980fps on a 0.8SD over 5 shots with a 2 ES. I now get a SD of 4 and ES of 8 over 20 shots (including cold bore). I really struggled to get to this point and hope this can help other fellow shooters.
