Well I have nothing small enough to push down the bore of this thing or I was going to shove a 36cal lead round ball nose down and measure.
So here I am just wondering, what sizing die would you guys recommend? I know some run the .309 but then I also read some run the .311. Is it true biggest is better (no pun, and it's NOT true!)? Would running a .311 when you really need a .309 do any premature damage to the rifle?
