S/42 Load Hornady 124 gr XTP with VV340

I must apologize for my ignorance of this powder, and did not realize that VV340 is the same powder as N340(according to the chart posted by mrerick). If this is correct, then I can help you out.

9mm Luger
125gr Jacketed Hollow Point

N340 Starting load 4.0gr Vel 937fps 21,000 C.P.U. pressure

Great! Many thanks for the information. You mentioned earlier that you keep OAL up for good feeding. I haven't a lot of experience with OAL 1.075, but what I have had exhibited some feeding problems at that length.

The VihtaVouri N340 published load for 124gr FMJ/FP (supposedly the "same" bullet) at OAL 1.142 starts at 5.3 gr and goes to a max of 5.7 gr with published speeds of 1139 fps to 1214 fps.

I have shot 115 gr XTP ahead of N340 5.2 gr at OAL 1.142 and speed of 1198 fps with no problem.

Given the age of this pistol, it would seem that starting at 4.0 and OAL of 1.100 would be safe and conservative. Make sense?
