No. I went with the weaver 20MOA and it has been great. Use blue loctite when attaching to rifle (not too much).
I agree with the base elevation recommendation. I went with the 20MOA base, no where near me that I plan to shoot 1k but you never know and it doesn't hurt.
Rather have it and not need it than need it and not have it.
As far as what rifle to buy for hunting. Get the lightest rifle you can find. Yes recoil will be more but a hunting rifle is shot often enough to stay proficient and not like a target rifle.
If you want a compromise I would say the varmint would be a good choice. Depending on what caliber you want the weight might not be an issue. .223 for example will be an easy shooter even in a light rifle.
