I plan on building a 300 blk upper for deer hunting as it's more cost effective for me than buying a new bolt gun. I know people build 300blk guns because they are very quiet when shot with a suppressor. That's really not my thing and I'm only going to use super sonic rounds since it will be my deer upper. Since I'm putting the upper together my self I figured I'd build it to harness the maximum energy potential of the 300 blk round.
Increasing barrel length has diminishing returns, and the information I'm finding online says the 300blk round burns all of it's powder 8-9" into the barrel. I'm guessing this is for subsonic loads, or does this hold true for super sonic rounds as well? Is it worth going longer than a 16" barrel for super sonic rounds?
Given my usage would the carbine gas length suit me better than the pistol or will the difference in dwell time not make a difference in bullet velocity? As I understand manufacturers are switching to the pistol length system so people can shoot subsonics more reliably but like I mentioned before I wont be shooting subsonics.
I'm pretty much doing the opposite of what everyone else is doing with the 300 blk platform which is making it hard to find the correct information. All my shots will be within 150 yards which is well within the capability of the round, but knowing I set it up just right for that extra 2% difference will give me that good feeling.
