Shortline line for 9mm 1:32 KKM

Anyone share a short line (possible lead) load for the 9mm 1:32 KKM?

Keep cost down from JHP and reduce snap of the 115gr JHP @ 1100+ fps.

I use 4.1 of VVN340 You can generally figure a starting point of ten percent less powder for a lead bullet verses a jacketed bullet of the same weight, 
Caveat. I have a frame mounted dot, and a 13 pound spring in the gun. And it is a 1911 9mm with a KKM barrel.

ps. I have the same setup but I'm running a lighter spring and I use 4.0 of WSF with the Penn's.

I use the Penn bullets in 115 grains for the short line in a 38 super under 3 grains solo or wst with and 8lb spring with a frame mount and 1911 platform
