    That Extra GPR Barrel

    A long time ago I snagged an extra lefthand flinter barrel for my Great Plains.
    Not real sure exactly why doing that seemed like a good idea but it did at the time.
    Any how, it's a fifty round ball barrel and could be rebored to a pretty fine minie barrel or paper patcher.
    Or relined to be a squirrel gun.
    Any yall put a squirreler barrel on a GPR? How'd it work out?

    I guess by squirrel rifle you mean .40 or smaller? That would make a pretty heavy gun!,,,Ed

    Longknife is right. If you swamped it out, you could lighten it some. It would be neat, though.

    @ Good Cheer.
    Buying things like that barrel keeps our minds working.
    It opens up all kinds of opportunities, plus keeps Bob Hoyt Busy.

    I started shooting matches in 84 with a .50 cal. cpr. 2 years later I got a hoyt .40 cal barrel 34" long put it on my gpr stock and used it for years. to me it balanced nice and held steady as a rock. I did not think it was too heavy at all.

    By squirreler you could very well mean 28 ga. I intend to do that with my Lyman Deerstalker (and maybe with screw-in chokes since I can’t find anyone who jug chokes smaller gauges). It wouldn’t be all that heavy and could be loaded as hot as a 20 ga.

    Wow. A squirreler and a large bore "smooth rifle"?

    I just sent my .56 T/C SB which is basically a 28 Ga. to Bob Hoyt to be Bored to .61 cal. and rifled in a RB twist.
    When I shot it as a .28 ga with Shot, it worked ok, but it was too heavy for any kind of Wing Shooting or Rabbits on the run.
    But I guess it would work for Squirrels where you are aiming more.
    Never got to try it for Turkey, but I bet it would have worked good for that too with #4 shot

    Yep, Got to order the new Lee mold in .600
    The set up should do fine for my needs, and be way more accurate than the Smooth Bore ever was.

    The .61 shot good so far.
    It grouped about 2.75" at both 25 and 50 yards with home made powder.
    I am going to try it at 100 yards next week

    I think I would be tempted to sell the flinter barrel and use the proceeds to fund the purchase of a 32 or 36 cal rifle.
    When you care enough to send the very best, send an ounce of lead.

    Wish I could find a 32-36 cal rifle for the price of a barrel ,I have lots of barrels and no 32-36 cal guns/

    No, I haven't.
    Salivated a few times over the liners' listing from TJ's in Alexandria, KY.
    My New Englander was set up with a .458 bore liner by Hoyt.

    Just this morning over coffee was looking things over and thinking about selling the .50 GPR barrel.
    What I really want right now is a rifle to shoot the Lyman 386177 (for a minie), the NEI 388-198 SWC PB (for a maxi) and .380 round ball. But then I'd probably have to have a companion revolver.

    Of course it would need a companion revolver!

    Good Cheer, why not line your 50 cal barrel back to a 38-55 liner with a .380 bore. Or better yet ... a 40 cal liner for 40-65 Winchester. You should be able to run paper patch boolits in it with the faster twist rate. Might just develop a patched round ball load with a smidgen of powder for small game and close in targets.

    Be a kinda heavy bugger but tall on cool and very unique to boot. Bench rested, the weight would be a none issue and with small hole nipples, it should be able to withstand plenty of pressure and develop a goodly amount of velocity for far away targets.

    Should be pretty cheap to uncork the breech plug and gouge out the barrel, then install the liner and drill the flash hole , then re-breech it. Plus seems like a great fun project.

    Wowww ... might just have talked myself into a project ... thanks for that!!!
