24 inch BHW Barrel really smokes with AA-2200 powd

[floatpilot]

I finally obtained some Accurate Arms AA-2200 Powder is REALLY lets the 24 inch BHW barrel show it's stuff.

This BHW barrel and powder combination makes the 6.8mm SPC viable for certain types of game out past 350 meters.

That is some pretty impressive speeds, and temperature, it was 96 here yesterday.

Those numbers confirm my suspicions. A 24" barrel is worth the extra weight. Thanks for sharing

My favorite length and one of my favorite powders.

I have posted photos of the rifle elsewhere on this site. It balances very well due to the type of fore-end structure I used and the A2 butt stock which fits my body just fine.

Since the 110 grain Accubonds have a minimum expansion speed of around 1800 fps. this BHW barrel made my old short range carbine into a 500 yard rifle.

Those are some Impressive numbers...should also work well in
our 6.5mm PCC BHW barrels as well, can't wait to try it...well done.

What profile barrel did you use: Light, standard, heavy, bull??? I was thinking of going with a 24" 6.8, but wanted to avoid excessive weight when hunting deer.

[GLSHOOTER]

Search his posts but it was a standard weight. I have one. .very usable.
