I have a badly pitted 7x57 rifle that shoots 2 touching holes and then one flyer. Repeat repeat.
I am wanting to try a different style bullet to perhaps beat the pitting.
For a pitted barrel, should one try a harder mono bullet or a softer deforming cup and core bullet ?
Should one aim for shortest bullet or longest style bullet of same weight.
I am thinking hardest bullet in shortest style with longest bearing surface to beat the rough bore, though some may suggest shortest bearing surface I believe the longer bullet support would be better.
I am who I am - I am not who you want me to be.
Therefore I am me.

I have pondered this question as well.
Pits lessen the structural integrity of the barrel, hence I assume that a kaboom situation is more likely. Once cut in, a mono bullet is said to have less pressure than a C&C bullet but how does it influence the erosion at the pits?
In the US, there is a company which makes extra soft bullets especially for pitted barrels. The theory is apparently that a softer bullets deforms and is less likely to get stuck.
