I load 73 gr of IMR 4350 behind a 165 Hornady or Sierra boat tails in WW or RP cases. This is a stiff load so approach carefully. Have used this load for quite a few years in 3 different Model 700's with no excess pressure signs.
My 300 win mag likes sierra pro hunter 180gr bullets rem large rifle primers (not mag primers) 80grs of H 1000,NOTE this load is 1 grain over max. I have no pressure signs. work up loads slowly watch for pressuere signs. I used this load in my Encore rifle.
winchesterbob I was thinking this also when I was working up this load with H 1000. In hodgdon reloading manual that's the primer (LR) they used. I called Hodgdon and talled to a teck and was told they will work fine. I have no problems using LR primers.
