What type of Ammo do you use? M195 type? (55gr) M855 type? (62gr) Another?

What barrel twist does your pistol have? What brand?

I'm just curious. I don't have or expect to own an AR15 pistol, but those things just look too cool! I saw Bushmasters Carbon Version with a 1:9 twist barrel, and thought I saw a 1:7 twist barrel on another. I was just wondering what type of rounds would be preferred for guns like these. My guess would be the lighter the better, being that the barrels are so short, but I could be wrong. I am new to this stuff! (AR15's)

Thanks for the info.

All of the 6.5/7.5s have a 1/9 twist, use anything up to 62 grains, the 1/7s could theoretically use up to 77gr or so, but out of that barrel, NOTHING will fragment, so just shoot cheap 55gr.

Thanks guys!

And thanks again C. Jack! As you know, I have been reading up on Ammo on the Ammo-Oracle which brought up my question on the pistols. Thanks.

What about specialty rounds like a 40gr then? Velocity should improve with the lighter bullet, maybe not to the point where it would fragment, but I would think penetration at least would improve. Ah hell, I guess getting SHOT would hurt like hell regardless eh?

Well, they may not be the most well thought out guns out there, but they sure look COOL. LOL!

40 gr would shoot flat, still not very powerful.

6.5s are fun as hell, and make quite a boom. Kind of a flamethrower too

Two or three feet long in the daylight, with the right ammo AND a good flash suppressor.

"For police-type work where a soft-point is desired, Winchester's 64 grain PowerPoint (in the Super-X line) and PowerPoint Plus (Supreme line) are top performers.* It has the advantage of being less sensitive to velocity by relying on bullet expansion rather than fragmentation, and is more consistent over a longer range of velocities. It would also be a better choice for use in AR-type pistols and short-barreled rifles, where the short barrels impart much lower velocities on the bullets. The downsides of this round are: questionable stability in 1:12-twist rifles, a smaller wound channel compared to a fragmenting bullet, and a cost of 3-4 times as much as M193."

From the Ammo-Oracle.

Jack....Now you make me wanna get one just for the FIREBALLS LOL!
