hello everybody,
I have no experience in swaging, but I tried a couple of times to make solid bullets with a precision CNC machine.
I have some experience in reloading , and looking thist thread regarding the right size of the bullets reminds me of a big issue I had with my dies.
Especially with Bench rest dies ( I'm referring to rifle BR dies, but I assume that there are BR dies also for pistols calibers ) some strange behaviour can happens.
I made solid bullets with the exact size of .308" and with my great suprise I discover that they got stuck in the die! ( Redding competition seater )
looking at my Lapua scenar bullets I found that they were .307" and not .308"
SAAMI specs and bore diameter are important , but I suggest to take a look also at the reloading seater die before swage a larger bullet to avoid the same trouble that I had.
my 2 cent.
ciao
