maybe.

Thanks. I'll pass this on. I'm still saving up my paper route money for the chamber reamer.

I think he was running 124 gr Blazer Brass?

Blazer Brass tends to have very poor plating; jacket separation has been seen by others in just normal handgun usage.

I have a GHM 9 with a 8.9" barrel machined in tri lug, and anything thats not FMJ/TMJ is terribly inaccurate (e.g. plated). Foot + groups at 25 yards. Huxwrx Rad 9. I stick to 124gr or heavier Federal FMJ/TMJ/JHP.

TMJs must be plated bullets.

Lots of great ideas.. Thanks. As far as the ammo, I don't think it was plated. The frags shaken out of the can looked like actual jacket material, but I could be wrong.

TMJs must be plated bullets.

Then I spoke incorrectly, FMJ w/ a fully encapsulated base. No electro plating.

I don't believe it's possible to have a fully encapsulated base without plating; there's no real way to draw a jacket over the base in an economical fashion, AFAIK.

I will note that plating can come in differing quality; shitty plating as found in the Blazer Brass bullets or Berry's Bullets work for economical loads, but there are also much more substantial plating like Speer TMJ or Gold Dot. Technically, the shitty plated bullets are jacketed, they're just very poor jackets that are nowhere near comparable to the quality and durability of a bullet jacketed via the traditional cup and draw method, while high quality plated bullets like Speer TMJ are much closer to cup and draw in terms of durability.
