H4227 in .32wcf?

[Bisley]

Hello, everyone. I have a Colt Bisley 71/2" mfg. 1906.
I am using the Lyman 3118, cast from a moderately hard mix of range-lead, WW, & 50-50 solder.
So far, loads using Bullseye, Titegroup, Unique, and TrailBoss have given good accuracy in that order.
Due to it's age, and value, I like to keep pressures low.
Has anyone had any experience with H or IMR4227 powders in this caliber?
Any other good powder suggestions? Thanks guys!

That is a very slow powder for 32-20 unless you are going for top pressure loads and even better in a carbine length barrel. You are most probably going to have unburned granules left in the bore. I occasionally shoot my 1912 7 1/2", 32-20 Bisley but I found that the slower powders require higher pressure than I am willing to subject the gun to in order to get a clean burn, I suspect either of the 4227's would be as bad or worse. I have decided to stick with Unique and Trail Boss. I also cast the 3118.

Hello, MMCSRET. Thanks for reply. When I got home yesterday, I looked up Ken PetLoads..He doesn't mention 4227 for this ctg. He does go on to say he had very good results with SR4756..I picked up a can today, and hopefully this nice fall weather will stick around for awhile. Thanks again!

I used SR4756 years ago, it burns clean and ignites easily. Should serve you well.
