Thanks.

I currently shoot the 200gr .40 Shockwaves in the gun (because I shoot this in my scoped Omega and can carry both guns with one set or reloads) or the 300gr Precision Rifle Keith Nose HP. I can tell you that it literally took a hammer to pound the 250gr .45 Shockwaves down the barrel, so it is a tighter bore (only made that mistake...twice!). I'll likely have to go with the .451s then.
