It won't cause me to, but it is affirmation for the heavy hard cast bullet and penetration. I accept his statement as good without any additional need for proof, based on his reputation alone.

My "most likely" is either a .45 Super or .460 Rowland, loaded with a 255 grain hard cast at 1075 to 1100 fps. In a Glock 21, that gives me at least 13 shots, 17 with the extended mags. I can run the Rowland up in speed, but recoil begins to slow repeat shot down. I don't quite have the "warm & fuzzies" with a .45+P with a 255 just yet. I'd like at least 1000 fps.

I do have a .44 Mag, but times between shots and time needed to reload are not as good as with the 45S/460R.
