Older stocks had 3/8 flats on the bottom, now everything is 1/2" and 5/8 for long range. round bottom is getting low as you can, but you have to ride on the sides. I like to ride on the corners on a flat bottom and if you come back into battery and the muzzle goes down the back is going up so you can take a little sand out of the ears or add some sand to the bottom. no big deal ...jim
