I'm anxious to know how the 225 fly as well. Since they're at the upper limit of weight and SD for caliber I'm sure wantin' to know how fast they fly and some long range performance empirical data when available.
Sorry but the heaviest I'm shooting is an old box of Honady 190gr BTHP which shoot great over 70gr of IMR4350 and traps me 2,920 +/- fps through a trap at 15' out. This is from a 24" Winchester barrel on my pre-64 custom. The barrel is a custom installation and I don't know who from. It's a hunting rig but performs well out to the 300 yards our range provides. I've got this nice new 26" SPS SS that I'm waiting for the range to dry out to shoot.
