200 Gr H&G 68 through a Kart NM barrel

Need some guidance. I've got a nicely built wad gun on a Springifled 1911 Mil base with a Kart NM barrel and bushing and the rest of the tune-up that goes with it. It's got a dot mounted on the slide. I spent some time working up loads using bullseye and found that 4.2 bullseye under a H&G 68 200 grain functions the pistol properly and drops the brass about 3 feet behind me. Chronographs about 775 fps +/- 40. Problem is that load does not do at all well on 50 yards. Would anyone care to share a pet load for a Kart match barrel in similar configuration that I might start with, rather than beginning all over again with the trial and error and bullet puller?

Thanks.

Not sure what brand bullet your using, but a we have a guy who makes the same hg 68 200 and with 4 gr. bullseye, 1.250 oal and .470 crimp they drop in the x ring @ 50 yds all day long from the same gun setup , if you can hold it there.
Different bullet brands dont always shoot the same even if the same style. I ransomed many lasercast 200, same 68 style and got sub 3'' groups with 3.9 of be.

Your load is fine. Make sure your bullets are as perfect as possible.

4.3-4.4 gr WST with the 200's has worked better for me than Bullseye with the same setup you described. 1-2 fingernail thickness' of lead exposed above the crimp (468-.470). 13# recoil spring. It shoots under 2 1/2" @ 50 yards with all my Kart barrels and functions in all 6 45's flawlessly.

I do like both BE and Clays for the short line. 3.5 gr with a H&G130.

FWIW

I've gotten good groups with 3.8g N310 under a 200g SWC



4.0g of BE or 3.8g Clays is worth trying with the 200g bullet.



I seat the Laser Cast 200g SWC to 1.235" or 1/32" shoulder protrusion.

I agree that your load is fine. I have a Caspian with a Kart barrel and I shoot a 185 gr SWC from a well known caster over 4 gr of Bullseye. Even though they all look good I weigh them all and save the very best for the long line and the rest for the short line. Yes its a bit tedious but worth it. The best shoot great at 50 yards and you'd be surprised how far off the average weight a few are.

Thanks for the tips. I weighed a batch of bullets. Two groups: one is about 195 and the other about 203. Some sports running down in the 180s probably due to voids? I suspect the caster was using different molds, or different age molds and mixed the lots. That might explain it.

From your description it sounds like we have the same gun. I've found that 4.0-4.2 BE works fine for me, but every pistol has its own characteristics. You might try 4.4 BE, or 4.4 HTG.
