Below are the targets from fire lapping my .308win. Took me a week to finsh. I cleaned the bore spotless between each 10 shot string.. After the first 4 steps I was loosing hope and ready to right off this rifle.. I just finished the last ten shot sting. Besides the first clean bore shot and the 2nd to last shot. ( I know I flinched) there are prity much in on big hole. Rifle specs are. .308 1:12 twist 18" sporter. It's the weatherby markv carbine. The load used was 40.5g imr4064 pushing 190g tubbs final finsh bullets. All groups are at 100 yards. The three on the right was at 25 yards. I was making adjustments to get in paper. I am fairly happy with the results.. My Next move is to replace the factory plastic stock..
