TMJ Ammo in a Hellcat Pro Comp?

[Bleemus]

Can I shoot Speer Lawman 115g in my Hellcat Pro Comp?

I know they tested TMJ ammo in the Hellcat Pro but can't find any reference to the Comp version and TMJ ammo.

I don’t see why there would be any distinction. How would they perform differently with a comp than FMJ.

I was always under the impression that TMJ and FMJ are the exact same thing...My impressions are sometimes a tad askew, however. Thus I am open to being corrected.

Some ammo labeled fmj leave lead core at the rear of the projectile exposed, tmj, in theory, does not.

Welcome to the forum, from Ohio.
The ammunition in question shouldn't present any difficulty.

With few exceptions they are like the same thing. Some m TMJ bullets might not have as pointed of a profile but they are pretty much close enough it’s not gonna matter. 9x19 9mm NATO 9mm Para 9mm Luger all the same.

And we haven’t had to do work to feed since like in the 70’s and maybe early 80’s
Your good!

TMJ should be totally jacketed and not leave the bottom exposed. Think @Annihilator when he goes for his check up. He would be FMJ, bless him.

Some comps will shave off the copper coating ejecting it into your face.

TMJ bullets are typically plated, not jacketed, and can cause issues in some comps/porting.

Little known fun fact: Lawman TMJ is the exact same bullet that Blazer uses.

As to it working in your comp/porting: it’ll probably spit jacket. But if you wouldn’t shoot Blazer or another plated bullet, you probably won’t want to use Lawman.

Wow. I didn't realize that.

Yep.

The only difference is that Lawman typically is the analog of a Speer Gold Dot load of the same caliber/weight.

Well damn, I learned something here today. Thanks curmudgeons.

Had no idea. Makes sense though. I’ve shot a magna ported .44 SBH, not unusual to get some debris buildup in the ports after shooting a bunch of cast bullets. Was unaware that jacketed rounds would spit through a comp.

Jacketed bullets are usually fine in ports & comps.

Plated bullets often flake off and spit fragments in ports, and sometimes in comps (ymmv).

Plated vs. Jacketed vs. Cast Bullets

Choosing the right bullet for your shooting needs is a critical aspect of firearm use. With a variety of types available, each with its own advantages and disadvantages, understanding the differences is key. In this blog post, we'll explore three popular types of bullets: plated bullets...

I have found out that this is a light relief of the bore that begins just before the comp so TMJ is fine in the Hellcat Pro Comp.
