I uniform my primer pockets again for consistency..
So they seat or crush the same everytime..
I've recently watched a video of an f class shooter who ran a test on seating primers and it did make a difference too ES's over the chrony from how much crush he put on them..
That's a bit anal but some like carrying out these tests..
I won't be trying it but since watching this video and chatting too a mate I've found my murom primers seat deeper than the fed gold magnums as the cups are shallower...
Too keep all things equal I'd need 2 pocket uniformers one for each calibre too save keep adjusting the uniformer..!!
Sod that....
