I stumbled across a rifle too interesting to pass at a gun show today. It was a Remington 700 in a McMillan game scout with ptg AICS magwell. It had been trued, tactical bolt handle and barreled by long rifles inc. It has a 26" 1-7 Schneider barrel chambered in 223 match. I couldn't pass it up.
As I looked at it I saw great potential for a fast twist 22-250. It seems to me the AICS magwell could be better filled with the bigger case. The 22-250 AI seemed like a no brainer.
I've seen a few things on the 22 creedmoor. It might be a more straight forward way to go. No fireforming and similar performance.
What are you guys running in fast twist 224. Planning on mostly shooting 75-90gr bullets.
