    Yes, as a graduate of TSJC, I can tell you that is what they would recommend on these "sentimental" gun projects. They can often involve lots of time and effort, which is almost never compensated...

    Could you specify the make and model of the action?

    Something that isn't appreciated by most non-match .22 shooters is that rim thickness is one of the big variables that affects accuracy in .22 rifles (and presumably handguns).

    It used to be that...
  5. In .22 target work, your best accuracy is almost...

    In .22 target work, your best accuracy is almost invariably had by using an ammo that is slightly sub-sonic in the firearm you intend to use (whether it be pistol or rifle).

    I've done similar...

    I'll have to dig back through my notes to find it. In the end, the results weren't that surprising, as not all barrels are finished the same (some are lapped, some are not), and they might differ in...

    Some tests were done on rifle barrels with the exact same bullet/load and they found a variation in muzzle velocity between makes of barrels - by as much as 175 fps on a 24" barrel at the muzzle....

    I've not been into a CZ Bobwhite. Is it a typical ungerlug locking block setup?

    If so, then here's what I think I would do:

    I'd remove the top lever and pull it from the receiver. Then I'd find...

    When I was a kid and using a ProMac chainsaw, I'd use straight 30W oil for the bar, along with a dash of STP additive for the 'tackifier.'

    A couple of things to take note of with Acraglass:

    1. It's epoxy, yes, but the #1 issue in bedding compounds is dimensional stability. As such, Acraglass doesn't keep shrinking the way that other...

    It looks as tho they should. They're all based off the .375 Ruger case. I think the .300 PRC would be the longest OAL of the bunch with the VLD > 210 grain bullets available. If the Winchester M70...

    The choke of a shotgun barrel is a relative constriction from the barrel's inside diameter a ways back from the muzzle to what the diameter of the barrel is just behind the muzzle (say, 0.5").

    My ATF examiner told me that the #1 criterion used by the ATF as to whether or not you need a FFL to work on guns is whether or not you're charging money for doing so.
