Old post I know.
I have an email into RST because my barrels are marked 65 but chambers are cut to 2.775” inches from the Barrel face to forcing cones. I’ve shot 2 7/8 inch ammo 2.7” OAL to the folded crimp) through it and it doesn’t pattern worth a darn I would assume that’s because when fired the fold crimps are overlapping the forcing cones. After the poor patterns from the RST ammo I only now reload only for my gun. I’ve cut all those same hulls down below where the fold crimp indentions are and use a 4 pin roll crimper. So my OAL length hulls I reload are 2.7” give or take. Short enough not to overlap my forcing cones. Needless to say, my patterns have gotten a lot better because I’m not using too long of a hull now. I wonder if there’s 2 5/8” hulls “ unfolded” are short enough (2.775” or under) so I use them in my gun? I would assume chambers were cut to the same length as recommended ammo lengths back in the day because they fired all brass hulls and eventually paper roll crimps? Sounds like in 1939 Remington invented the star crimp( fold crimp). I would assume chambers were lengthened to accommodate modern star crimps and 2 7/8” chamber detentions were lengthened a good half inch for the fold crimps when they “ un folded” when firing? Anyways, I have 13 number fives and six number sixes still in the factory boxes that I’ll never use. Guess I can either try and trade them for the shorter versions or some brand new 10 gauge hulls? Be ashamed just to rip them open to use them for halls after I paid way over 30 bucks a box plus shipping back in the day when they were available. I look on there and I see they have 2 5/8 inch light loads and not 2 7/8 inch. They also don’t offer lead anymore for some reason. I’m wondering if they only offer 2 5/8” ammo now because they figured out a few years back what I’ve just figured out.
