MGM 257 Wby
I bought a 257 wby barrel recently and have noticed something while breaking it in. Ive prolly got 80 rounds thru it now, and used the standard breakin ritual.. clean every shot for about 15, then every 3 or so for the first 40 orso. The past box ive shot i was noticing that after about 5 shots.. my groups really open up! I cn get 6 shots out of a clean barrel, including a "fouling" shot before it starts to scatter. Just wondering if this was common with a 257wby cuz this is the first one ive owned. Maybe the barrel just "fouls out" quick....
