I recently picked up at the range some really nice LC 07 brass that I decrimped and FL sized and went against my better judgement and used the same recipe (24.5gr H335-CCI 400-55gr Hornady V-Max- Win brass) as I normally do with winchester brass I use. I got keyholes and strays in my target at 100yds. I have never had anything less than great accuracy out of this savage 12fv. the only thing changed was the brass.
Maybee I got the barrel to hot, even though I only shot 50 rds in 1 hr?
The first 30 rds were normal recipe with winchester brass, and it was right where it normally is on the target. as the session progressed, it went from great accuracy to wondering why I was a couple inches off, to flat out strays and keyholes .
I didnt think brass would make that much difference, but Ill go back to my tried and true load and eliminate any variables. the only other thing was the barrell seemed warmer than normal. I shot many more rounds than this in a day during the fall, winter, spring and didnt have heat issues though.
Any thoughts? I know I did wrong by not working up a new load by switching componants, but did learn a valuable lesson from it.
