    If you are looking for accuracy, you would probably have to replace the .224" barrel with a .222" rimfire barrel. I would also expect the bolt would have to be converted to a two piece bolt with a...

    We have and can tell you from experience, they work with 300wm, 30-338, 338 edge and 30stw for over 1000 rounds.

    So how much flame cutting/erosion do you see after 1000 rounds?

    You can always bid the job as "Time and Materials" and see how that flies. You take it if the customer takes it.

    Have you done the math for this? M15 is nominally .590" and 5/8 is .625". that gives you .035"/2 = .0175" thickness in which to cut the 24 TPI threads. Looks like the minor diameter of 5-8-24 is...

    So is it essentially impossible to build a retro 10 with the charging handle in the carry handle from purchased parts then?

    I suppose you could design one from original parts if you had the right...

    What about repairing the receiver? The safety is not at the high pressure end.

    1 mm pitch is 25.4 TPI so 25 TPI would be better if your machine will do it.

    Might be a good idea to make a sleeve that you could slide onto the barrel, true, and let it ride in the steady rest. Unless you remove the fluting entirely, you will have ugly burrs left on the...

    No idea if you didn't have an infrared thermometer to measure it. But Loc-tite melts around 400°F so if you had torque on the barrel while you were heating it and twisted it out once it started to...

    If you have Parkerizing on the inside, I would do something to smooth it. New Parkerizing is pretty rough and will "bite" into soft metal like cartridge brass which likely is your problem.

    4130 will not get as hard as 4140 because it has less carbon. That makes it better for welding.

    Website prices may be out of date but that is his responsibility, not yours. Might be interesting to see if he has corrected the website prices or he is false advertising to fish in customers.

    The only issue I see is getting the new forcing cone concentric with the bore. Most revolver barrels are not simple cylinders and holding will be a challenge.

    I’m still not seeing any degradation based on tack welds.

    The problem will be that the welds will be very hard and brittle because they will be rapidly cooled by the large mass of surrounding...

    If you are still intending to tack weld the lug to the receiver, I would do it at 3 and 9 o'clock only. With the breech locked, the bolt lugs are at 12 and 6 o'clock; no reason to get any heat in...

    I am not familiar with that model. Rifling causes the shot cup to spin which makes for a really loose pattern. A smooth bore would be better. I do not think drilling out the rifling would be a...

    You're going to have a brittle weld in you don't do the pre- and post-weld heatings, and they will likely anneal the receiver. I would not go that way. Instead, I would go with some kind of key...
