I shot LSWC's and RNFP bullets and could not see any difference on paper. I shoot offhand and my accuracy criteria is how many times I can hit my 50 yard 12" gong target.
The Lead RNFP slide into the chamber easier and so that is what I am using.
I use 8.5 grains Unique with 250-255 lead, that hops around 800-900 fps, sometimes less, and the load is accurate.
If I'm not shooting, I'm reloading.
