You'll be fine with 308 especially shooting 30 rounds...Yes have to love the bang on a 308. Even better when you blast an animal with it!! In my avatar that's what I'm shooting an AR-10 308. But I prefer my bolt gun and it also depends what you're using your gun for. Each style and caliber...
Like I said it comes down to caliber. For instance 243 Ackleys are barrel burners and if you're shooting long distance you will see your group spread out versus say a 6.5 creedmoor caliber
One thing that helps is not sending a bunch of rounds down and making the barrel hot. That would be a sad...
What's the deal with all these flaky people?? This place at one point was a good place to do deals without worry. I have yet to experience a deal that has gone bad and don't want to. It's just really sad!
I'm not a fan of that place! Will never buy anything from them. They need to train their employees what customer service is! I've had a very bad experience and the owners wife is a witch....and that's me being nice
