Ive had one for 30 years, was my deer/goat culling rifle, back in New Zealand, likely got 5-6000 rounds threw it, 2500-3000 head of game at a guess, still shoots well enough for hunting,

mostly I used a 50-55gr soft point, from Norma/sako or PMC, never had any luck with the American ammo, that was aviable, at that time late 80's -1998 when I left NZ. still shot the odd goat, or Fallow deer with it, one or two, every couple years, for old times sake, Ive carried my little vixen, over thousands of miles, of mountain country, lot of memory's,

I would look at a 53-55 gr soft point, the serria 53 shoot well in mine, five in an Inch, I tried the 50g TSX, yep no good, 6" pattern, 60gr the same, except the flat base hornardys, they shoot ok, at 100m, 2", no good at 200m,

Generally my vixen, will shoot any 50-55gr bullet into a 1", 11/4 for five shots, often a lot better, but the old 4x32 wever steel glass, is the ####s, for sun glare.
I use bench mark, or H322, 22-23 gr, what every primer is cheap, and what ever brass, I have on hand, Its the only rifle, I've not put any effort, into developing a load for, I just go hunting,
I don't think, I've really helped you, but you've got a very nice rifle, That is plenty capable of Coyote's, and in other parts of the world, is used on much bigger game.
