Those 3 groove jess rebores pick up velocity. I had at least 60-70 fps increase from his rebores when compared to 4-5 groove factory barrels of equal length.
His rebores polish up nicely too, if you clean with abrasives like kg-2 on an oversized bore snake every 3-5 rounds. Leave the kg2 in the bore and continue firing. 100 rounds later, fouling with pure copper bullets will be significantly reduced.
If you ask him, he'll cut a front sight dovetail free of charge.
He apprenticed with an old school barrel guy, and assumed the tooling. A far more experienced "old timer" process, than these idiot millennials operating mass production machinery like the above mentioned ruger guide gun in 30-06. Jess fixed "state of the art" with "dated" processes.
Thanks for that information. That's a reason to choose the 3-groove.
I've not used the KG-2 before but just looked it up and it seems very highly reviewed.
What do others here think of the suggestions from mainer_in_ak? Anything to add on the technique?
Thanks,
Rex
