Would re-barreling a short .308 to a necked-up caliber like .358 Winchester or 8.6BLK be effective?
Similar to how 300BLK works better than 5.56mm out of a short barrel. Less muzzle flash, more powder burn, and more energy on target?
Also, post other big bore stuff
ksg sbs with slugs will be better
here's a crazy idea: shorten a 6.8 SPC and neck it up to .40
Underrated comment,
heck might even work in a pistol.
Why not just push an icepick into your ear much cheaper

Why is that, Leon?
>Would re-barreling a short .308 to a necked-up caliber like .358 Winchester or 8.6BLK be effective?
Of course. The .358 win is the most efficient form of the short case.
358 win is the least efficient, it should drive the same weight bullet as 338 federal faster than 338 fed, but it doesnt.
Wow she is perfect. Who is she?

I need to know god damn it. Please anon, I beg you, who is she?

Check your math, show your work.
The HK53 was used by bong SF as a "SMG" chambered in 5.56 NATO, sounds pretty decent
Whoever designed the HK51 and said "this is an acceptable platform" needs to be hanged.
yeah but it's really funny
>Rebarreling .308 to a necked up caliber
.44automag bruh
Just checked the numbers, .44AMP is really close in velocity to 300BLK and .308 out of similar length barrels.
If I get a wild hare up my ass, I might actually build this monstrosity.
or just get a .50 beowulf upper and call it a day.
honestly you are FAR better off just going straight to 300 BLK with a barrel that short. You are getting absolutely nothing unless you use very specific loads meant to fragment at very low velocities in 308, and 300 BLK will happily shoot subsonics from an 8" all day long and be very quiet to boot.
Yeah, but AR stuff doesn't tickle me the same way. Hoplopfheil did some testing, and found that the velocities of .308 out of the PTR51 were about the same as 300BLK, just with extra muzzle blast. That's what made me think of this.
Good thought, that one slipped my mind.
Or, you know, a round that actually exists, like .350 legend.
>350 legend.
>vs. .358win
Say you're under 30 without saying you're under 30.
Yeah, it's almost 4x the price for a round with significantly lower efficiency in short barrels. The problem is that you WANT short for caliber projectiles in short barrel guns because they accelerate faster and absorb energy from the powder faster. Otherwise you waste case capacity or have a shitload of muzzle blast. Also you can just get 255 grain subs for 350, or 150-200 grain HP supers for it.
What do you need to convert an AR to .350 legend? Barrel, bolt and magazine?
That looks like a .300blk lancer mag. They make actual .350lgnd mags for AR's that would probalby be more reliable. How does converting over work?
Bolt is the same.
...you guys know that you can increase the pressure of older cartridges safely in modern rifles, right?
The lancer mags suck, get a CMMG steel mag.
You need: a barrel and a new mag for last round reliability. Bolt and everything else is the same.
I assume you mean for the wrong caliber but then so all mags. Nothing wrong with cmmg but Lancer are fine magazines, for their designated caliber.
I bought ones labeled for 350 legend (in that pic. With the mag loaded to 20 rounds, it's rated capacity, you have to hammer the mag in with your first to get it to lock in. The lips open up under the tension of the rounds.
I'm not sure if you've seen the fireball from an 8" .308 but firing one of those off is like getting slapped in face. You can put a side facing compensator on it and really make sure that absolutely everyone at the range hates your guts. Why bother rebarreling it.
8.6 BO is just shitty 338 federal, moron.
.358 winchester was designed shittiliy, fairly low pressure.
Go with 338 federal, or up to 375 raptor.
Wouldn't switching to a bullpup design and having a relatively normal barrel length be better than coping with some wonky close range chungus destroyer extreme chode round?
