Shot out in 800 rounds? Ya the 243 is not the most barrel friendly round but 800 rounds?
I convinced myself that the old Ruger sporter I had a few years ago was shot out but that was only because I wanted to re barrel the dang thing anyway, truth was after 1200 rounds of doggin and deering it was getting a little tired but would still shoot MOA (even new it was never much better than that).
My second 243 is a Savage J action that I bought in like new condition that now has 1050 rounds (from me) of 55 grain Noslers with 51.5 grains of H414 down the barrel. I've let it get hot but not smoking shooting at prairie dogs.
This group was shot yesterday and is pretty representative of what its still capable of.
Maybe I've been lucky cause I sure aint good but it would be interesting to know have a little more info.
Define shot out?
What cleaning rod do you use and do you use a bore guide?
What cleaning solvents used and how long left in barrel?
What powder was used?
