coyote hunters: 17 squirrel&mink

[king canis]

i'm new to the board, but no stranger to 17's. my first was a 17 ack bee on a 310 martini cadet. i used it to kill a lot of coyotes for about 10 years, last 4 years it hasn't seen much action. the past 2 seasons i have used the 17 fireball. i have registered a few kills in the 350-400 yd range but don't recommend trying it often. i have used 25 gr hammets(gone, but the woodchuck den bullets seem to be the same thing) and bergers with great success, 25 gr hornady hp was a disaster (didn't get the job done too well). i haven't tried any v-max in 17, good yote bullet or turd? i shoot 14.5 gr of h-322 in the bee, 16.5 in the FB. i have noticed a large difference in noise level between the two despite the small charge weight difference, both are hot loads. this has sent me down the path of wanting to build a quiet gun for coyotes. as in call, shoot, keep calling, distant coyotes not spooked. i intend to use a 28-29" barrel to keep noise down& velocity up. i am considering the 17 squirrel or mink. i am leaning toward mink since cases may be easier to form. bullets in the 20-25 gr range. anybody using these cartridges on coyotes? this gun will see use 2-4 days per week during the pelting season. please relate your personal experience. thank you.
