Is it possible to cut down IVI 7.62 blank brass (remove the crimp at the top of the casing) and reload it as well?
It's possible - just a lot of work involved. I did this years ago when I had some dead blanks. The best thing to use to get the tops off is the RCBS Trim die.
It's got the hole in the top and you use a hacksaw blade to trim the whole mess off the top. The die is meant for this purpose - trimming, but not trimming blanks.
I didn't do many because it was a PITA to do a lot. Better to use regular IVI cases and perform match prep work on em.
I happen to really like IVI cases - good and strong - just gotta reduce the loads, due to internal capacity. I think they are on par with Lapua cases - once you go through the necessary steps to match prep em:
-I anneal them, becuase you don't know what they've been fired in
-FL size to conform to standard size, before you fire form them to your chamber
-flash hole reaming/chamfer and primer pocket uniforming
-primer crimp removal/swagging
-trim to standard uniform length
-check neck thickness and neck turn to uniform thickness
Once they're fire fire formed, then you can just neck size and shoulder bump for case longevity. I anneal my cases, because I have an annealing machine which makes life so much easier - I can do it all the time with no effort!
With the frequency I shoot and annealing, I'll have cases for the rest of my life hopefully.
