I have cast for a few calibers over the years, the .357 and .38 Special were by far the most I did, with some .41 Magnum and .45 Colt behind it. Now that I have a Winchester 1885 (original) in .32 WCF I want to cast for it, and it seems to really enjoy .312" but I want to try with the heavier bullets, the 100-115 grain bullets. It's an older gun, made in 1889 so I don't want to push the round too hard. I want to use this gun on coyotes, although here in the northeast, our deer killing range in some parts is well under 100 yards and a really well placed shot would do well with a good hard bullet I would think.
