Assuming your foxes are close in size as ours here in the US, pretty much any slug will work at that range or closer. I would use something like the Nielsen light to mid weight slugs. With a standard Superior STX liner the low weight for caliber work best for most people. Speeds you will want to be in the 900-1050 range for performance, but your liner/setup might not like going that fast. But for a very rough estimate my older Impact does ~1005 fps on a 150Bar tune with the Nielsen 34.9g and lots of upgrades in a 700mm.

Red foxes average 10-11 pounds. That isn't as big as raccoons or coyotes get but it's a lot bigger than a squirrel or rabbit. I would be concerned about getting enough penetration especially at 60 yards with an expanding slug (on a body shot). I test penetration in wet magazines to get an idea of the penetration in muscle tissue. I would want to see penetration in the 15-20 magazine range for an animal the size of a fox. My little P35-25 is just short of 50 fpe shooting JSB 34 grain pellets and will shoot through 19-20 magazines (at 25 yards). So I think it would be OK on foxes with that projectile although I wouldn't want to go all the way to 60 yards with it. But I get much less penetration with expanding projectiles, sometimes only about half. 9-10 magazines is my desired penetration for squirrels. 9-10 magazine level of penetration will shoot through a squirrel if you do not hit the shoulder and will reach vitals even if you do.
So whatever you use I would test penetration if you think you will be taking body shots. The first criteria for the projectiles and tune are that they be accurate in your gun. You also need enough penetration to reach the vitals, however, even if you hit the shoulder.

I head shot 2 foxes (30 and 40 yards) with a 25gr .25cal pellet at 650fps from the muzzle. At 30 yards it had 20fpe of energy and at 40 there was 18.9fpe of energy. Both dropped dead. I wouldn't have taken body shots with that rifle/combo, but they were easy shots and they were waiting for the dog. Any heavy pellet or slug going over 900fps is approaching the performance of a .22cal rimfire, so body shots shouldn't be a concern at the distances you are taking about.

Might want to try Altaros slugs (boat tail). Not sure of the weight. Got to shoot a .25 Panthera with those & we were making shots out to 286 yards! You could contact Centercut & ask about specifics (it was his gun). Don't know why but 37ish grains is sticking in my mind but doesn't mean that's correct.
