I have been working on OCW testing for my 220 swift. I took everyones advice from last time and went up from 3 shots per charge weight to 5 shots for initial testing. I will add the photos of the targets and would like to get some opinions on where to go from here? Do i have 2 nodes, maybe three? Do i need to shoot 10 shots or more in a specific node? Test Details. Projectile was Hornady Varmint 55 grain SP Powder was H380 Range 100 yards Test was 5 shots in .3 increments. Starting at 39.0-41.7 grains testing was done over three days. the wind was mostly calm with occasional breezes head on.
