Just picked up a Remington 742 with only a few rounds shot through it.(Absolutely flawless) I know the reputation of this gun so don't start. Of course I cannot find ammo so I was going to have a friend load for me. Winchester Large rifle primer,H4350, Hornady interlock sp 150gr. Are we close? Not sure if auto will affect action as to going heavier on load or lighter. Due to current powder shortages this is what I have available. Hodgon reloading data called for bt bullets.
