A year or so ago I have built a 25" 300 Norma & looking at building some more of them.

I have one to build with a 26" barrel just waiting on the Defiance action.

My reamer has been used on a couple of other 26" builds, one of those started at 28" & was shortened, a reasonable velocity lose was recorded but with a "little" chronograph.

I'm trying to find out potential velocity differences between 26 & 28" barrels with the 300 Norma & 230 Bergers ?

Any info would be greatly appreciated thanks.
