Yeah, last time I looked, it cost something like $2000 an hour to fly in a chopper? I hope thats not true, cause not many people can afford that. Do they have a bounty on hogs? Maybe they should use the hogs as live targets for training our military. That would be cool!
Depends on the rifle. My 280 needs to be bare metal clean to shoot a decent group. My 22-250 will go hundreds of rounds before accuracy fails. My 7mm-08 needs to have 11 rounds down the tube, after a cleaning, to shoot at all. My 30-06 and 257 Ackley shoot whether the barrel is clean or not.
I went throung the same thing with my grandfather(76). He refused to admit that he couldnt handle the recoil on his '06 anymore. I bought a nice recoil pad and came up with a mild but effective load for it. Really helped out.
Take at look at the bolt. I'm betting there is a place where the back of the bolt handle rides against the action when it is closed? This is how they used to headspace 22's back in the day. This area wears down over time and you lose your headspace. I've fixed half a dozen 22's with this...
