Need to know my correct trim to length for .357 magnum. 2 of my books say 1.285 and another 2 say 1.290. I looked at the SAAMI specs and it calls for 1.290 -.020. I am leaning towards 1.285 but could easily be talked into 1.290
Yes I know most folks do NOT trim pistol or straight wall cases. Well I have cases ranging from 1.280 to 1.298. That makes it hard to put the same crimp on each case as I reload, so I am trimming all to one length.
TIA
