Whatever the gun likes. Sounds like you are not hand loading...
Factory Hornady "White-tail" 100 gr is one of several that my 700 likes. Likes it best., tho by a small margin over Factory Corelocts. DOES NOT LIKE 95 gr. Remington Accu-points (I think what called). Shoots a couple lighter bullets fine also, but I've always stuck with 100 gr for animals (sheep, caribou, moose).. Likes Federal 100 gr. also.
Best to shoot, not ask us- guns are all different.
I've heard good things about the Fusion too, tho I haven't shot it in my own rifle. The only rifle ( friend's) that I tried it in (his ammo), I wasn't impressed, but that might be the rifle's preference. My Corelockts in his gun performed much better, on paper.
Buy 3-4 boxes of 100 grain, 1 each of different brands and go shoot.
.243's are funny, and I don't like 'em much, tho I've had mine for going on 40 years and killed a chit-load with it....it's light to carry and no recoil to speak of.
