in all honesty: you have to 'ask' your own rifle! it is true that every rifle is a law unto itself, as you may have seen elsewhere.
i'd order sierra's and hornady's if going hunting for coyotes. i'd order hornady's in 80 gr' weight at most. the sierra's are generally known for lighter-jacketing and their boattails may be what you want in that brand if going for shots beyond 350 yards. you may want to try nosler's, but they'll probably cost you a fair deal more than hornady's.
do not use a magnum primer. Accurate Arms 4350 works well for us loading for a buddy's .243. it is a tack-driving Model 700 using Sierra's 100 gr btsp.
take care,
