Model 21 barrel steel

Mark, i am certainly no expert in this but my inclination is to not shoot steel through that nice gun. No need to really with all the good non-toxic alternatives today. I would buy some Kent Bismuth and shoot away with no worries.

It was really sort of a rhetorical question, since I have been feeding my very early Parker lifter 10 RST Bismuth at $3.00 a copy, it is not the economics.

I agree about tempting fate!

Mark, If I were you I would NOT shoot steel through those barrels!

Winchester Proof Steel is indeed Chrome Moly 4340 or 4130 and was introduced in 1931 for the Model 21 and reported to have a tensile strength of 115,000 - 120,000 psi with an elastic limit of 105,000 psi.

The "Violent Proof" (VP) load was reported to be 7 1/2 (long) tons = about 24,000 psi by Burrard's conversion

Steel target loads have a thick shot cup and I would certainly use them in a M21 with no more than an IM choke. Sadly more gun clubs are being forced to convert to non-tox only ie. Naperville (Ill.) Sportsman's Club and some in CA
