very nice. Wish Kart would leave all their barrels short chambered by .020 - .030...

Are you sure about your decimal point placement?

MBacker,

Great work and ecstatic someone has picked up Jerry's torch.  Thank you for continuing to keep innovation alive and well.

Have you had a chance to try the faster twist barrels with 185/200 gr LSWCHP/LSWC out of a barrel fixture?

Cheers,
Jay

JayhawkNavy02,



Testing is in process with Zero 185 JHP and Zero 200 lead swc.  I will report back on results.  I know Jerry had an outstanding 15 shot group with zero 185 jhp but I believe these barrels will shine with lead. The land/groove design will minimize bullet distortion and the bore finish is fantastic.

This picture is the muzzle end of the Douglas:

The next batch of barrels will come unchambered.  This will allow the chambers to as concentric as possible and customized. I have incorporated many of Jerry’s ideas into custom built reamers.  Negative SAAMI spec, 1.5 degree leade angle, free bore are just a few aspects of the design.

Neat project, my 1911 has a Kart barrel and the chamber is longer than spec but it shoots well.  The bore on mine is nicely finished.  Let us know how it turns out.

Very nice.   It will be interesting to see results as people finish pistols with these barrels.
