Well, I finally decided to get dedicated batches of brass for the Springfield and the R700. I can't afford Lapua, plain and simple. They had some bagged new, unprimed Winchester at Cabela's, and I could see in the bag (and based on what I had already read), that they would need some work to load (case mouth indentations, etc.), and some may need culling. I was actually pretty surprised after diving in, the bag did actually have 50, no shoulder dents, it was easy to round the case mouths using a neck resizing die mandrel, and it looks like all but 2 have centered flash holes.
After rounding the case mouths and numbering them with a marker, I went to use the Lee lock nut/trimmer for .30-06 Sprg that I had very successfully used on my multi-fired Remington (R-P stamp) brass. A few of the cases are long enough to be trimmed nice and square, some are lopsided so that only a portion of the mouth gets cut, but the majority don't quite reach the cutting blade, so I can't cut them to a perfect square mouth.
Is this an issue? Should I just de-bur, chamfer, load and fire? Will once fired brass stretch in my SAAMI throat/chamber and allow square cutting after fire forming?
Don't chew me out too bad. I've only worked with pre-fired factory load brass; this is my first experience with new brass prep.
