I shoot anything over 32gr for coyotes I read here that the 32's were prone to splashing. The berger 35gr shoot really small groups and work good on yotes although I haven't had a problem with noslers or hornadys either as they seem to work equally as well. I have a box of 39gr bk's that quite honestly I just haven't had the time to work up a load in yet. My personal jury is out on the Barnes varmint grenade, although I have a decent load, key word decent, they did make a few prarie dogs just plain disappear in a cloud of red mist. Long range, 250+ performance is doubtful in any kind of wind more than a breeze. I personally reserve the 32gr. bullets for smaller than coyote size game although that may change if I run into a few and have drt performance.
