I just ordered 700 rounds of the Browning 22 lr 40 gr HP rated at 1400 plus fps. Been wanting to try them for a while.
I've seen it advertised on a couple of on-line ammo vendor sites.
It interests me but not enough to buy 700 rounds for testing.
I would buy 700 rds in a heartbeat. Put a hundred rounds through my 22/45 at the indoor range last week. Only one misfire out of the bunch, and the group on the two inch bull at twenty five yds was impressive.
