Went out today with the WSSM to do a seating depth test to try to improve the 45.6 grain load, if it needed any.
I set out with 50 charged cases, my press, bullets, calipers and comparator. I already had 50 loaded up at the original OAL of development, so I thought I'd shoot them first to see if any changes needed to be made. I put up my homemade "shoot 'n see" targets on a stand in the F-class bay and raised it up for the test. There was quite a bit of wind today from right to left, so I dialed 2.5 MOA into the scope so I could hold right on my dot every time. I did the shooting at 600 yards.
I shot 2 shots and was impacting right so I took off 1.5 MOA and fired 3 shots.
Holy SCHITT! Got lucky with the conditions.
I let the barrel cool while I shot my .300 WM at the same range only to see the load needed some work. After the barrel cooled on the WSSM, I took out all of the wind correction on the scope and fired a 5 shot group in some variable 10 mph crosswinds.
Hey Tanner! That's what NO VERTICAL looks like!
Tough to beat or improve a load developed by the AUDETTE METHOD.
I just started seating bullets into the charged cases at the same OAL and shot some more for fun. The 5" plates were easy at 430 and 550
