Non-Toxic question re: Damascus using gaugemates

[Jawjadawg]

Should I expect 2-5/8" chambers, intended for use with 2-3/4" shells? 12ga GH made in 1898.

As I dig deeper, that is what I read here but also take note in these threads that paper shells were the norm in those days. I'm unclear exactly how that difference impacts the expected pressure vs using today's plastic shells.

Will, I just compared my Nice Shot 20s to some fresh RST 20s. The crimps are quite similar. Like yours, they appear to have been roll crimped after being star crimped. The Nice Shot box labeling states that they are loaded by Classic/RST.

Those very good crimps on the Niceshot loads . My guess is they are closed using a spinning head finish die that looks similar to a roll crimper. Much the same as most european loads are crimped.

I shot 30 or so of the Niceshot factory loads this season , (that were crimped the same way), out my SweetSixteen and did not have that problem.

Not sure why the hull mouths were torn so badly , but as stated may be due to short chambers.

Call RST and ask them.
