I have a factory issue ASM in 32-20 and I don't recomend this load to anyone else, but it works for me and is the only load I shoot in my 32-20's. I use the origional load for this cal. Almost. The origional loading was 20grns of Black Powder by volume under a 115grn cast slug. I use 1.3cc (About 20grns by volume) of American Pionier Powder under a Meister 115grn RNFP bullet and havn't found any reason to ever want a diferent load. I havn't shot any varments with this load, but have taken a couple 'youts out to about 60yds with my 32H&R Mag using the same bullet and slightly less powder. (1cc, about 15grns by volume) in the 32Mag. I see no reason that the 32-20 shouldn't work as well with the same load, and it's real plesant to shoot.
And to me, there's just something special about doing my shooting with the loads that were used a hundred years ago. Back when the cartridges were designed.
But then, I still hold my pants up with suspenders insted of a belt, too, and havn't left the house in over 30 years with out a hat on.
Could be maybe I'm just a tad old fashoned. LOL!!!!!
I don't have adjustable sights on my handguns, I adjust them with a file for one specific load, then stick with that load forever.
