Re: Barrel break in

Most high quality custom barrels will stop fouling badly within the first few shots.

I usually do one-and-clean for the first three or four rounds, not to 'break it in' but just to see whether the barrel was lapped correctly and to make sure it's not otherwise a bad barrel.

I had one barrel that would not come clean: After a three minute soak with Butch's the dry patch kept coming out a deep dark blue, even after over forty shots. That barrel never cleaned-up properly and it always shot poorly. It was replaced under warranty.
 
Re: Barrel break in

My experience with factory vs premium aftermarket barrels tell about opposite things. Regarding premium aftermarket, the above reflects just about the same as I found with my L-W replacement barrel. After a few shots, it usually stops fouling aggressively. I clean for the first few, to determine when that fouling rate shifts to negligible, but that's just 'cause I'm a control freak.

Factory barrels are seldom produced to the same interior finish standards, and the fouling reflects this. But I am not at all convinced that aggressive cleaning during initial shooting has any meaningful effect on how soon the aggressive fouling will abate.

IMHO, the only significantly beneficial wear-in occurs as the machining marks from the throating operation are abraded/ablated down. This occurs as a normal part of the natural shooting process.

I give a rifle about 100 shots to settle down the throat before I begin serious load development. Those first hundred shots are most useful for the pressure testing and fireforming processes.

Im am also of the shoot & clean & dont waste time with 1 shot/clean - 5 shots/clean...never made a difference in the last 45 years of building my own shooters.

Man I miss NOBODY, hope he is doing well.

Also have you read the barrel break in sticky at the top of this sub forum?

 
Re: Barrel break in

I have been amazed at the 1000's of various answers and opinions on this subject. I think people should follow the directions they feel safe and comfortable with. Whether it be forum advice or a manufacturers. I have never offically broken in a barrel and agree with those that shoot however many rounds they want and clean when you get home. I have rifles that I "forget" to clean sometimes and they shoot just as well dirty the next time I am out. Maybe the powder gods just shine over me when I shoot.
 
Re: Barrel break in

My brand new M1A barrel now has about 240-250 rounds through it and I never cleaned it once. Don't intend to either as the groups shrunk from 6-8 inchs at 200yards to 2.5-3 at the same distance after about 80 rounds.
