AR15 What Caliber

[powderburner]

I have 2 complete lowers. One is going to be a 6.5grendel

I can not for the life of me settle on what the other should be.

I have a bolt action 223 and a Ruger Ranch 223 so I am good on that one

I keep looking at the 350 legend or 300HAMR but I know someone has an opinion that I need to listen to

Buddy had a 350 had feed issues sold it for a 300 blk

458 Socom

7.62x39 just make sure you get the right mags or you will fail to feed issues.

My vote would be 7.62x39 as well. Have a Bear Creek Arsenal Side Charging 16" upper that can make 300 yd hits on 7.5"x12" steel target.

Very happy with the HAM'R.

Depends on what you want to do. A 204 Ruger varmint gun would be great and so would a short 300 Blackout.

I have a 6.5G and 7.62x39. The x39 is on my hog rig and the G does the rest

7.62x39 gets the most use from mine! Have two and they get pulled out of the safe more than my 300 or 556

450 Bushmaster is a thumper. So is the 458 SOCOM. 50 Beowulf. They all fit in an AR15 sized package. Serious power. Ammo availability is a factor.
7.62x39 is a great caliber also. But again, with the Russia thing and all. Ammo?

My 458 is fun to shoot and if you reload bullets are easy to find, if you don't reload it seems I can find 450 ammo but never 458 or 50 Beowulf.
It's hard to find something that fills a niche that your 223 and 6.5 don't in an AR platform.

I really like my 6.8

300 blk. I don’t want one and then I see a video with a suppressed 300blk and want one again. Then I look at ammo prices and don’t want one again.
