For that a 22-250 is hard to beat.i don't usually shoot heavy for caliber and this would be around a 300 yard rifle. good points for wind and dust spots on long range targets
Ive got a 22" .243 m700 barrel you can have, it's got wrench marks on it and could probably use a recrown, but still shot pretty good. I can polish down the marks, fill them and duracoat if for you if you want it.I've got a Remington 600 that i want a longer barrel on it, so i was just going to pick up a used 700 barrel on gun broker nothing fancy. i think it would make the perfect truck or just bumming around the desert rifle plus i really like the Remington 600 it just needs a longer barrel
