I have a very nice 12-2 flat-latch snub that carries quite well in cargo shorts or some Wranglers. I really don't want the gun to suffer the classic under the barrel frame crack. I understand that not all loads, even with equivalent fpe, impart the same stress on the platform due to velocity, projectile hardness, etc.

Which of these non+P loads are "harder" on the firearm, and which are "easier"?

Ballistics from a 4"V barrel:

158 gr XTP at 800 fps / 225 fpe from Hornady

158 gr LRN/LSWC at 755 fps / 200 fpe from Win, AE Fed and Rem

150 gr LRN at 845 fps / 238 fpe from Winchester

130 gr FMJ at 890 fps / 229 fpe from AE Federal [shoots REALLY good in my snub!]

130 gr FMJ at 800 fps / 180 fpe from Win and Rem

110 gr JHP at 950 fps / 220 fpe from Win and Rem

Thanks for your input!
