    Bartlein New Barrel Material 400MODBB

    That's 30 passes per groove. 5R barrel means 150+ passes.

    Bartlein New Barrel Material 400MODBB

    I've chambered several of them. As you would expect they machine differently than 416R. But no real issues. No special tooling required. Reamers may not last quite as long but at a cost of approximately $3-4 a chamber for a HSS reamer in 416R what's another 50 cents. For carbide the increase...

    Gunsmithing When should the bolt start cocking the FP?

    If that's addressed to me about the bolt cam the only fix without affecting other relationships in the ignition system is welding, then recutting the cocking cam. Pretty extreme just to change the feel.

    Gunsmithing When should the bolt start cocking the FP?

    Neck clearance is important for consistency. Don't hesitate to change bullets. If a barrel doesn't like a bullet there is nothing you can do to make it shoot. I wouldn't spend any time worrying about the bolt. There's nothing you can do to change it.

    Gunsmithing When should the bolt start cocking the FP?

    Tell us about the rifle. Who made the bolt? etc. The most important question is what does the target tell you?

    Gunsmithing When should the bolt start cocking the FP?

    You have to have room for some movement. Otherwise the firing pin bottoms out on the camming surface. That's not good.

    Monolithic solid projectiles in polygonal rifling

    The 33XC barrel had heat checking on the outside edges of the lands for about 8-10". I would expect to see that after many many hundreds of rounds at which point the throat would have been long gone.

    Lugs galling

    I don't know the whole story about your rifle or have I seen it but no there's nothing to worry about based on the pics you put up.. What you feel is from manufacturing. Smooth as a babies butt is not what you want.

    Lugs galling

    It's not the type of galling most of us think about but it appears something happened with one lugs. Maybe a piece of debris between the lugs. There's nothing to fix so I would just keep them clean and lubed.

    To Torque or Not to Torque?

    75-80 ft/lbs Which means I lean on the action wrench with a mild grunt

    Accuracy International AT Barrel Questions - Lothar Walther?

    Myself and many smiths can spin up a barrel for you. I did all of AI's barrel work for a number of years when AI North America first opened.

    The Fix from Q

    Your 22 creed may not have a chamfer. I don't recall ever chambering one.

    The Fix from Q

    E All the barrels I did from day one had a chamfer and the end gap on the bolt was the same.

    Lugs galling

    Oh yea it will be very noticeable. Not what you would call normal wear. The only thing you have to do to fix it is remove the high spot/ball at the end. I do it with a Swiss file. Maybe a quick light lapping to make me feel better.

    Lugs galling

    A pic would help a lot. Lugs will develop marks just from wear. A galled spot will be a groove ending with a ball of metal at the end. I never want lugs to be too smooth. No place for lube to hide out. I've galled lugs sitting at the dining room table before there was ever a barrel screwed on...

    Lugs galling

    What do the lugs in the action look like? You might find your answer there. Galling will roll up a small amount of metal(high spot). Almost always in one spot/arc with a corresponding groove on the opposing lug.

    Gunsmithing Robert Gradous

    Robert called me twice. All revved up about something. Probably something I said that he didn't agree with. I was waiting for the ass chewing. We talked for probably 30 minutes each time. He never got around to saying why he called. We'll miss him.

    New Sig CROSS

    That's for the 16" barrel. And my guess is it will be July before any ship. And that's just a guess.
