Thread: .243 Varminting

It's not a big calibre, but I'd use the steel recoil lug for sure.
The action screws can't be tourqued too tight without damaging the plastic stock anyway. From memory it's about 30-35 inch pounds. Just go easy.
I'm not a big barrel break in believer, but on my last barrel I used a borescope. shoot 1 clean one, three times ran off a lot of burrs. Then just used it.
I didn't clean it hard out, just enough to push the crap out between firings. Oh cleaned before the first firing too.
