556 223 SBR Ammo?

[Barth]

Looks like heavier bullets are the trick?
My new baby has a 10 1/2 in. 1 in 7 chrome lined hammer forged barrel.

Should work good in it, that 1:7 will stabilize the heavier bullet better, at least on a normal barrel...with one that short it should still work the same. That's the type of bullet I'm wanting to throw into some hogs hopefully in a month or so.
