that came out nice bub\d. We'll have to match chrono data someday, see what that long barrel gains over a 16" AR and a 24" bolt.

Beautiful gun. There is a guy named David White (D&T Custom Gunworks) that does a lot with the .357 Max and other straightwall cartridges. You might want to check him out.

Thanks cutright. I have been on his sight several times. I'm looking forward to seeing what I can get out of both of them.

At 38,000 p.s.i. you could put the .450 BM in a T/C Contender as well couldn't you? That would also make for an interesting pistol!

Factory ammo today on the chrono 2396-2420. Produced just under a inch using a bipod and a not so stable picnic table. The range was tied up today at the club with a conceals weapon class. So I played at home with what I had. 43 gr of lil gun and a 250 Xtp ran 2680 fps with no pressure signs. Just added recoil. Lol

Ken-
Thanks for your report. Please continue to post information about your results with different bullets and powder. We locked-breech 450B users need more data points. Some more information on the handloads as you develop them will be most helpful. Primer? C.O.A.L.? Crimping techniques? Case mfr?

A couple of questions about your rifle, if you don't mind? I can't find the answers in what you've posted so far, but I certainly could have overlooked them.

What's the final weight on your rifle?

What is the muzzle diameter on your barrel? I cannot tell from the photo whether the barrel contour is a straight taper from breech to muzzle or something else. If straight taper, what's the breech diameter?

You've produced a fine looking rifle, and one that is apparently fine performing also.
