Fairly hefty

a little large for some game. I like .30 cal for general purpose. .30 is also 7.62, btw.

I'm considering buying an upper for the ar15 platform

Fair enough, I was also considering either a 5.56 or 7.62 upper

the 7.62would be a better all-purpose round

Ya but $$$

yeh

How about for handguns?

I'm considering a glock 19

I like my compact .45 Colt Commander. Sometimes short, fat, and slow do the job nicely.

Sub-sonic ammo and packs a punch

Pros of subsonic?

No sonic boom.

Basically, that's all

Still loud?

Oh yeah, as loud as any other. But, if using a supressor, you don't have the extra sonic boom.

True but then you need a tax stamp

Also, sub-sonic doesn't pass through as easily

Yes, you need a tax stamp for the suppressor. Of course

I like the .45ACP for general purpose. It's big and heavy and slow, so if you hit something with it, that something knows it has been hit. Even works for bears.

Damn

I think I'd feel bad if I killed a bear

At least without the intention of eating it

a 9mm fmj can pass through an assailant, if you were being attacked, and that assailant will keep coming

Well, yes. We don't kill for sport. i live in a place, though, where bears occasionally get into neighborhoods.

Mine's coyotes mostly

Eastern PA and Jersey are known for bears

I would like to eat another moose though

Tasty

Now THERE you might need the .450

9 foot tall giants

@Old_Greg 300 BLK subsonic rds with a suppressor is only as loud as the buffer spring and bcg and the brass ejecting from the chamber. Basically.. ie you wouldn't need to wear ear protection, and they fly slower so they dont pass through walls in CQC as easily limiting collateral damage to non militants potentially on the other side..

I always forget the .300 AAC

Yep, many, many uppers and barrels for this cartridge.

Lol oh yeah

Does it use the same bolt? I think it does.

You just need to change the barrel

I think it needs a different buffer assembly, I might be wrong.

Bigger spring maybe. Those things are all modular, swap parts

I have a DPMS Panther in 5.56
