Well I got out the "T" today and went and pushed a .314 lead slug through the Barrel. Took the calipers to my wife for checking as I measured a whopping .3085-.309 ! ! ! She came up with the same thing ! ! !
Now I realize that the "normal" for a .303 is .311 +- on when/who made the barrel, but this is ridiculous ! I then ran another one down the bore and came up with the same thing.
So, I am going to get out the moulds and see what I have in something around .310-.311 and see what they will do.
Am I correct that I want to have something about +.002 larger than bore diamater with the LEAST amount of sizing??
I will be using 3031 and working up/down from something in my Lyman reloading manual to see what the rifle likes.
Thanks,
Chuck
