Fellas:
I've never played the HV cast game; 1800 fps has been plenty for me. But, I would like to qualify Appleseed KD that goes out to 400 yards with a 1 in 12 twist FN rifle. The course of fire requires 4 MOA accuracy from sitting and prone; the rifle is more than capable with jacketed. I don't want to play alloying games and am willing to buy my first ever non-WW scrap alloy. What Rotometals alloy would you recommend to make this as painless as possible?
Current boolit of choice is the 30XCB from what I have read here, but have never shot it. I also have Lyman 311291 and 311284, RCBS 30-165 and 30-180SP, and an unmarked 30-(looks heavier than 180) in Magma blocks that was a gift from BD. I have discounted the flat nose hunting boolits as too wind resistant/more wind drift, but this is from no practical experience at all.
Your long range and higher than average speed cast advice much appreciated.
Tony
