After about 120 rounds and many screw ups I finally struck pay-dirt this morning. 57.5 grains was the hottest charge that I had to try, and 57 grains didn't group worth a crap. I didn't have any confidence in only 1/2 more grain charge, and I had a three of them and I let them fly without even confirming where they were hitting. Looked through the spotter and said "no way". Walked downrange to pick up my best 300 yard group ever. I am so happy for what I have learned to get to this point, all of the time and money spent is finally starting to pay off. Thanks to everyone here who has helped by answering my sometimes ridiculous questions, I wouldn't be here without you. .280 Ackley Improved 57.5 RL 22 Berger VLD 168 .010 Jump to lands 300 YARD 3 Shot Group!
