Most popular barrel length?

Post by armedruby »

I'm thinking about building one of these. Does it matter if you plan to shoot supersonic or subsonic with a 300 Blackout? If I build one, I'd shoot both. Most look like they're building SBR's. That the most popular format or am I just hoping so....cause I really want to build an SBR. Got my paperwork going now.

I sell more 10.3" barrels than anything else. 16" is next, followed by 9" followed by 18" then 12.5".

Interesting. I'm not at all surprised by 16", but I am surprised about 18", and also would have thought 12.5" would rank higher.

Lots of 3-gunners wanting to use this to make major so they dont have to tote an AR10, I believe that is the reasoning behind the 18"ers.

Also, you dont really get spectacular gains going from 10" to 12.5" so most people will opt for the shorter system.

Velocity gain slows down as the barrel gets longer.

What data was used to create that chart? The reason I'm asking is because I am interested to know what and how to achieve the maximum supersonic potential of this cartridge in an Encore or bolt action platform. I don't think I've found any reload data for loads much faster than about 2200 FPS.

Is 2500+ FPS possible with the blackout and 18-20 inch barrel assuming the use of a 110-125 grain bullet? Accurately?


Thanks.

300 BLK has been verified to do 2450 for 110 grain in a 16 inch barrel below 55,000 psi.

This data is a QuickLoad simulation based on a 110 grain bullet and H110 powder.
