Re: help with .270 reloading
You did it bass-ackwards.. Start at the minimum and work your way up.
Many guns do not like near-max pressures and velocities. H&R/NEF guns are one of them. You get wider groups with them and near max loads.
Factory loads are generally nowhere near the max loads due to liability and unknown factors like what quality of gun the ammo is going to be shot through.
Since you can get 1" groups with factory loads, I wont advise you to inspect the scope, mounts, and muzzle/crown first. ..but you really should load from the bottom of the charts first, then work your way up until groups start opening up, then back it down to the last "best" group.
