A 6.5 Norwegian Krag Bubba sporter followed me home recently, the groove bottoms are pretty frosty, maybe freckling would be a better term. Anyway, I have a large inventory of jacketed 120's and 140 spitzers that I could burn up...with the idea of
1. fire lapping the bore with a little very fine Clover compound
2. getting some idea of accuracy potential ( I lose interest fast if after the usual accuracy killers are checked and a rifle won't shoot)
So the real question, how much do these old long throat profile barrels resent the use of short light bullets?
The original Norwegian loading was a roundnose of 156 gr.
