i am starting a new builld. i ordered a broughton 8 twist 22 caliber for my remington 700 short action. i am wondering what is the best case for hunting coyotes and might shoot a f class with it for fun. i am planning on shooting the 75 grain a-max or 80 gr berger vld. please let me know you opinion. i am hoping this gun will last for awhile. worried about the throat in these calibers.
