I've only shot 170gr loads out of my Glenfield 336 30-30. My cast bullet loads are 175gr. With factory 170gr Core Loct at 100 yrds off of a rest with a scope i usually get just over an inch. About the same with my hand loads. The factory Core Loct load is actually a little more accurate than my hand load.
Just to add this is with a fixed 2.5x scope. With a higher magnification scope I would probably do a little better.
