I only shot 150 and 165 gr bullets in it.But it didn't kick bad.I shoot a lot every week and to me the 270 kicks worse than the 06.At the range I have a cheap slip on butt plate for the kicking calibers and it sure makes a difference.
Went back and looked at the target it looks like 180 but it is 150.The load is 53.6 grs of R-15,when useing 165 it was 57.5 grs of IMR 4350.
