    Gunsmithing Is K&P rifle barrels still in business?

    Ken was the one I just missed meeting during my tenure at HS. He left right before I started, and got back in the area just after I moved to Scotland. Good guy, great work. He don't know me from Adam, but Chad give him my best from Florida next time you see him --JR

    How were '03 and Garand barrels rifled?

    Frank, it's the cold work that gits the stresses into the material. It's kind of like muscle memory, work a steel alloy around when it's cold and it's still trying to get where it thought it was in the beginning. So how I ALWAYS order is make sure you stress relieve that f'in steel bar after...

    Maybe Bleiker got out of the bbl game, know they were working on getting into it just after I left Scotland. Grunig and Elminger a definite ex customer. Glad to see them trying to roll their own, maybe Geoff helped them out

    How were '03 and Garand barrels rifled?

    Frank, this is in open court so I'll be brief. you ever need anything for GKH on boring and reaming, I've been at 15 yes 15ipm drilling 6mm holes straight on GKH, bang on for muzzle runout on drill and better than 16 surface finish. It's a method learned for sure, and you go thru about 3...

    BTW, we, meaning Border, made most of Blieker's barrels before they started rolling their own. so there are some jewel cut rifle bleikers out there

    Well I can attest to this. We use the same steel I started purchase orders in 2009, buying in 45T at a time and bringing in 45 T at a time. In other words it's our mill run. Not all barrels are run by 11595 spec, there are waivers and specific callouts in the mil specs. Look up M240 and...

    How were '03 and Garand barrels rifled?

    Frank, the easiest way to answer the question is we hold chambers and bores to x tolerance to maintain repeatability. Match barrel grade. Chrome might slick a surface up for feed, but guys like you and me are more interested in the tenths when it comes to repeatability of process.. So take...

    How were '03 and Garand barrels rifled?

    What Frank will probably agree with me in saying is within the erosion pattern difference of CM and SS, CM tends to start slowing down at a pace. SS stops cold. For accuracy sake, seem to chase the tail on CM when you know you are done with SS. Chrome lining is great, other than when we do...

    Haha, must be all this cooped up nonsense. 11595 spec calls out for three types of 41XX for many mil barrels. But there are other steels used for full auto which the military does allow or waive or specifically call out for that particular barrel assembly, most of which are a 'cleaner' grade...

    Boots has been in some way or shape involved with every cut rifle barrelmaker alive today. He, like most of us doesn't believe in keeping the knowledge of the dark art to ourselves, if there is genuine ability to be created from the curiosity of the person asking the questions. It's not an...

    Aye, Border eventually morphed into Sassen after the sale but there's no proper Border guys there. Anyone who might have been with Border during the move that stayed did not get the full benefit of that core group that made that team a brotherhood. Border was Scotland, after they left the...

    Steve if you're reading this, kudos. There are more recoil 'moments' in a gas gun than bolt gun, and you are on same track as we've been working on here. Takes a barrelmaker Later JR

    I honestly don't know one way or the other, but do know both setups they use for KAC platforms so would be able to tell if factory chamber or not.
