This thread has me anxious to try out my still pretty new to me 9 twist 220 Swift this spring! It may (probably will) become a 220 Weatherby Rocket by then for even MORE fun with rodent launching.
I sure wish it was legal to use this rifle on deer in this state. A 55gr Barnes TTSX at about 4,000fps from a 1 in 9 twist barrel would seem to be a pretty deadly combination, but the pencil driving buerocrats in Olympia obviously know better, right?
I wonder how fast I will be able to drive my favorite little 36gr Varmint Grenades with 45 or so grains of powder behind 'em?
This rifle with my stash of 75gr A-Max's ought to be pretty effective on Coyote's as well.
