Forming Cases and other things

[J.B.]

Interesting comparison there Jim, especially the additional depth afforded by the Bertram basic cases. An additional .135 - .150 is quite a jump. I'd be curious to know how much of that is brass thickness vs case length vs head thickness. It's all a bit academic as I'm finding 84 x Swiss 1.5 is more than enough to get the job done.. provided I get my side of things in order . I have some Bertram 45/110 cases sitting in my workshop so I might just run a couple of them through the sizer to see how they pan out. The Norma basic I tried once worked a treat but then Jamison/ Captech came good with supplies at the time so I stopped pursuing that option. Only wish I'd had a few more dollars at the time to lay in more JBA cases . All of my cases have shortened on firing but the JBA set back the least. I managed to get hold of one of the BACo 50/110 cases to try and still have some of theirs based on the 348 cases. All have worked without issue but for my part I've not had the ability to swage the rims either in diameter or thickness. Once fired though I'm not sure the rim thickness is as critical if being shot in the same rifle ?
