Yes - fast twist and throated long. I bought the Browning A-3 with it's 26" bl. for long-range shooting at our range.

We have now extended the range to 1,400meters last fall. We need some more steel plates - obviously. Another full size buffalo silhouette out of AR500 would be nice.

It only took me 2 shots to hit the 1,000meter buffalo. He's 4' belly to top of the back and 8' long including the head, of course.

The reason it took 2 shots, was I held my Vortec MOA scope for 1,000 yards, not 1,000 meters. The second shot (anohter 1 1/2 moa smacked him in the heart.

180gr. WW Protected point bonded - factory ammo.
That 180Winchester and some old 1970's .300 Win. Mag. R-P 180 Corelocts (I found) cloverleaf on top of each other off the bags at 100 meters.

That test target had 6 shots under 3/8" - for factory ammo, it was incredible. I picked up another box of the Win. ammo just to have it.
