Throat Erosion? Opinions

[Bigwheels]

It's been a while now, so I thought, after the 5/15 Steel Challenge I'd check my throat. It's moved .007" from the time I did my load work up. It still shot well enough @ the match, but I haven't done any groups lately. Should I rebarrel soon with about 1700rnds in a 300WM?
BTW, I'm wanting to put a brake on it anyway.

I would be curiouse to look in that barrel. If you know someone with a borescope, that will give you a better idea on where the barrel stands.

You could always put a brake on it and shoot it until it dies that put the brake on the new barrel : )

Good Luck,

LOL, only .007? my 7WSM went .038 in just 500 rounds. Shoot some groups, play with the seating depth if you have to. If it shoots good, why rebarrel?
