Yeah, absolute fps is way down the priority list. This 77 is a 1972 model and it does have a fairly long throat. Forgot the COL but again that's way down the list too as long as it shoots. Doesn't like either the 120 gr Sierra or 120 TSX. Those were trial runs that didn't warrant pursuit after the Accu loads were shot. You know, off the subject a little, but after deciding anything over 250 yds would be a long shot for my deer hunting I started sighting in our deer rifles (6.5 Swed, .260, 7mm-08, .270 etc) at 200 yds and discovered all tended to be about 1 to 1 1/2" high at 100 yds and even closer to POI at 50. Seems to work with velocities from 2700 t0 3000 or so with bullets from 120 gr to 150ish. With this midrange trajectory and enough velocity to make a bullet expand, hitting and killing deer is achievable.
