I use a Nikon Omega with 5" of eye relief on mine.I'm shooting 300 gr. bullets at 2363 fps.in mine and it's not hard on the shoulder,and very little muzzle lift off the bench.Mine has the compact stock and the hot loads feel about like a Handi rifle with the factory Win. 300 gr. load. Mine gets alot of use for hogs,and deer. Digger
