Thread: How short on a 303?

there is in deep dark recesses of my memory a method using braces rubberbands (teeth braces) on the case for first firing to hold it against bolt face...and resizing appropreately from there on in.... someone with better memory than mine will know it.
very tidy rifle...good on ya for giving old girl a new lease on life.....
was using the same S&B factory stuff the other day..the projectiles look shorter than other fmj types we had misfire issues till gave bolt a plurry good dung out.
