So I bought a bag of this brass at Cabela's last month on sale and finally opened it up. The brass looks like new and goes into my case gauge nicely sized but it measures 1.740. I measured half a dozen and they are all very close tolerance but I thought that 1.750 was the short end and I always trim to 1.755 and if I go over a bit I can still hit 1.750 on a separate pile. I put 1 thru my RCBS sizer die just to see what happens and I can get 1.742.. Any thoughts? Still fairly new to reloading and so I like to stick to the cook book as much as possible..
