Thread: Sizing loaded ammo?

What you could do is buy a RCBS trim die, these dies will put the shell back to factory specs. I used them in 30 06 and 308 when we were using semi autos so we had no issues with tight rounds. Ideally you should do the trimming , sizing etc before you load them but you can do them when loaded. A friend had a heap of 308 shells he had FL resized but would still not close the bolt on his rifle until I ran them all through the trim die. Make sure you use a little lube as you would for FL sizing so you don't get any stuck shells in the die. This should work fine for your problem.
