243 or 270 would be fine for deer. 270 would work for elk but 30-06 or 7mm mag would be better. 243, 270, 308 & 30-06 cost less to shoot. I think the 783 is a good choice it felt just as slick as a Tikka to me and cost a lot less. If you don't like the plastic stock you could get a Boyd's stock and $ total is still less than a Tikka. Later if you decide you want a different caliber 783 barrel can be changed yourself just like a Savage. Savage would be a good choice also.
