I loaded some 45 XTP loads at around 4.9 gr of 231, CCI primers, new brass. OAL was on the short side, 1.22-1.23, some even in the 1.21 range. The felt recoil and sound were very anemic. Hardly any recoil at all compared to other target loads I've used. They shot and cycled the gun fine, and very accurate. Question is, when I loaded I was actually worried about them being too hot with a short OAL. What would an overpressure load feel like (not to a KB!)? Are they like hot loads, or does the pressure just build, then release with the bullet without any obvious recoil or noise? I looked at the brass a bit, but didn't see any case bulging or anything. I need to check the primers more closely to see if they expanded into the hole.
