I have been loading 32 S&W Long for about 40 years. here are a few things I learned about lead SWC's in that time.

Don't worry about leading the barrel. Proper fit is important, but some barrels lead no matter what! (Even at the high 900's you should be fine!) I believe it has to with the type and quality of the rifling.

The discontinued Hornady 90 grain SWC is soft lead. wax lube and very accurate! The Lee 90 gr SWC tumble lube shoots poor no matter what hardness!

A RNFP of the same weight is more accurate than a SWC, because of the higher percentage of bearing surface.

On small game, a solid hit with 90 gr SWC's is a good show!
