Funny, I was able to see pictures of the shells showing crimp end yesterday (they showed fold crimps) but today I followed every link I could find and could not find the same picture.
I do wish them well and hope they are able to get going and expand their offerings as there is certainly a need. The only gun I have which has 2.5 inch chambers is a 20 gauge and I am now reloading for it, but it is good to have options. It would be nice if they would sell fewer than 10 boxes per order though.
As to listing pressures, in their defense none of the major shotshell manufacturers (at least in the US) report the pressures their shells generate, and I don't believe RST does (did) either.
