Take whichever one you like. I honestly think the sheep hunting rifle is one of the most over thought decisions in the entire world of hunting. Most guys I know here in AK just use a tikka or a Kimber with a lighter scope and do fine.
About 5 years ago I had a buddy who drew a really good sheep tag. He bought a tikka (back when they were less than 600 bucks) and put a 6x SWFA on it. He bought about 3.5k rounds of 308 ammo for it and just practiced his ass off, learned how to dial etc. practiced a few times a week. Just shot the heck out of that rifle. When he found his sheep, he was so comfortable with the gun that the 560 yard shot was a chip shot for him.
A few months after that he was on a Facebook sheep hunting group and somebody was asking about cartridge choice for sheep. He suggested a 308 and a lot of practice and the ever so knowledgeable Facebook sheep crowd just had a field day making fun of 308 etc. well that dude has gotten sheep every year since and a stone in Canada with that same exact rifle/scope combo.
