There is a lot that can go into a tripod, but I think it would help if you decide a couple of things: cost, weight.
There is no doubt that ARCA rails and clamps are the best for locking the rifle in. So that is done. The issue you have is mounting the rail to a rifle. That's not difficult, but you have to make the decision to add a rail. Some people freak out over drilling holes etc.
Leveling head vs ball head. I have both. I am currently using the leveling head with RRS QD clamp. Ball heads are sweet but there is a little more movement due to the height and design. Generally I need rear support for use with a ball head and shots over 500. The leveling head is pretty solid to 1000 without a rear support. The ball head offers a bit more versatility. I added a panning head with qd mount for the days I may be glassing and want that smooth movement for hours of glassing.
I've shot coyotes, deer, and wolves off my tripod. Furthest yote so far is 1125, several from 800-1000. Wolves 38, 515, 750. Deer were all 300-400. This is all off a light weight but yet pretty durable tripod. If you want a 1500.00 setup and amazingly stable, it'll weigh 7-10 lbs easily but I'm not lugging that around the rugged back country.
