Which Powder for High BC .22 Bullets?
I am awaiting a 8 twist barrel from Krieger. I have designed a new wildcat with about 22-250 volume but with a small primer pocket and a 40 degree shoulder. The reamer and gauges are on hand.
The intention is to shoot 75 and 80 gr .224 bullets at 600 yard bench rest at my club. What powder will I want to use?
I have experience with lighter .224 bullets but not the high BC bullets that an 8 twist barrel is capable of. Which bullets are likely to be the most accurate? Which ones should I avoid? I am told the 75 AMax is the value bullet in this field (cost vs accuracy). Are there any other value bullets? The Lapua bullets are the most expensive assembly line bullets. Are the Lapuas worth the expense?
