I’m using a suppressed 11.5" in 5.56 and I’m trying to decide between M193 or M262 clones. Palmetto started selling some really affordable 77gr OTM.
Military guys seem to really like 77gr SMK, but energy numbers seem to favor light and fast 55gr. I have a theory that maybe the longer 77gr bullet yaws and makes a bigger hole, but other people online say it’s the fragmentation that counts.
I also have a 10.5" in .300 Blackout, and 110gr V-Max to get the maximum velocity and stopping power out of it, but I can’t afford to practice with that gun as much.
I home carry a Glock 17. But if I have an AR-15 nearby, and the bad guys are still working on breaking down my door, it stops the problem faster and more precisely, with fewer projectiles going out into the neighborhood compared to a pistol.
That’s a good point. I think I’d rather use an AR for the same reason. Would a frangible round make sense to mitigate wall penetration and potential ricochets inside a home? Or would penetration (or lack thereof) be an issue?
I wonder how frangibles would work on concrete blocks? My exterior walls and some of my interior walls are made out of them. Most houses around the Arizona desert seem to use them.
Then again, even FMJ won’t penetrate concrete blocks right away. The first hit shatters the block, or part of it, and the second or third shot goes through.
Assuming a passthrough in three shots is actually really generous to 5.56. That assumes that I keep hitting the same spot over and over. That’s unlikely for HD.
A .308 or similar will destroy the block on the first shot, and either clear the debris or passthrough on the second shot. But it also won’t penetrate on the first shot, although the shattered concrete can hurt.
