As any experienced hog hunter knows a 5.56 is all that you need for brain or spine shots, but we don't always have the opportunity to take those "ideal" shots and have to go for a lung shot from time to time. Also as we know big hogs very rarely go down quickly with a lung shot and almost always run 20 to even up to 100yds. I've shot a lot of hogs in the lungs with a 6.8, .308 and 300 HAM'R and based on "my experiences" they normally run further when shot with a 6.8 than they do with either the .308 or 300 HAM'R which seems to put them down the same. The only calibers that I've shot hogs in the lungs with that put them down really quick is the .458 SOCOM/HAM'R or a 9.3x62 with 286gr Nosler Partitions.

We have only built pistols with 11.3" bbls and mine gives 2320fps with the 130gr HotCore and still shoots sub-inch, it's my "car gun" for traveling.

We did a velocity test with the same bbl gradually cutting it from 20" down to 12.5"

150 SPEER FNHC 12.5" bbl 2105 FPS (-41)
TOTAL VELOCITY LOSS FROM 20� TO 12.5� 97 FPS

ALL TESTING WAS DONE WITH THE SAME BARREL PROGRESSIVELY SHORTENED FOR NO BARREL TO BARREL VARIATION AND ALL AMMO FOR EACH LOAD FROM THE SAME LOT. ALSO ALL SHOOTING WAS DONE DURING A 5 HOUR PERIOD ON THE SAME DAY USING A LABRADAR TO MINIMIZE THE EFFECT OF ATMOSPHERIC CONDITIONS. ALL CHRONOGRAPH STRINGS WERE 10 SHOTS WITH THE HIGH AND LOW SHOT REMOVED FOR AN AVERAGE OF THE REMAINING 8 SHOTS.

AS YOU CAN SEE AS THE BULLET WEIGHT WENT UP BARREL LENGTH HAD LESS EFFECT ON VELOCITY. AVERAGING THE 16.25� TO 20� NUMBERS IT WORKS OUT TO 10.5 FPS PER INCH.

mc... your name is now mc hammer and that's an impressive hog!!

colt... i'm writing the president of hooked on foniks and demanding they give u a refund... in bit coins

crown royal... you were close but no cigar. you can't kill a hog with a 223

if anyone thinks my songs are too old, gfy

That shooting is more up to your standards.

Just assembled my new upper with a 14.7" lightweight barrel, hoping a few extra inches will make a small difference in terminal performance vs. the 12" 6.8 and 6.5's I've always used for night hunting in the past.

I haven't read through all 45 pages of this thread, so apologies in advance. Is anyone seeing a significant difference in function between regular GI mags and 300blk specific mags? I loaded up one of my metal GI mags yesterday and seemed like they weren't laying in there just right.

You will not get reliable function unless you use Blackout mags, both Lancer and D&H function 100%. This said, we will have a new WC 30rd POLYMER mag out next week that functions 100% with 5.56, .300 Blackout and 300 HAM'R.

I've had zero problems with 300Blk PMAG's running 300 HAM'R.

Bill, side question: Do you have any idea how much barrel whip there is in the 8-inch HAM'R barrel? I finally got my suppressor, which I'd planned to mount partially inside a 9.5" handguard. There is maybe a 32nd of an inch between the can and the handguard. Curious if it will hit it when firing?

@Wilson Combat

Load data from "Wilson-Combat-300-HAMR-LOAD-DATA-5-20F1.pdf" mentions a bullet called "125gr Hornady FMJ", which bullet exactly is that?
I found only SST and VMAX in that weight but they are not constructed as FMJs.

Bill can confirm but I believe they are the Hornady #30196.

That is correct and it actually shoots really good for a FMJ

mr wilson...

how many rounds do you think it will take to shoot out a ham'r barrel? i've got to blame my missed shots on something. shouldn't these things be warrantied for at least 10,000 rounds?

Crews. Have you tried a standard spring on it or flat wire spring. So far I have tested all 110 gr sp and the best configuration that have found is standard buffer weight and spring and Magpul 300 Blackout mags
