Hi there everyone anyone else reload 7mm rem mag for target shooting
Im using 168 grn smk hpbt and reloader 22
i have worked the loads from 57 grns to 63 and although there is signs of the primer flowing back im having no other signs of pressure no sticky extraction bolt closes and opens just fine. Im stumped anyone else had the same issue? the rifle is a remington 700 sandero 26" flutted barrel

Brass make?
What brand of primer?

Some 700's exhibit primer flow signs purely as a feature of the firing pin hole design, before high-pressures are reached

Hornady and weatherby cases and cci 250 magnum primmers
the weatherby cases are 7mm rem mag cases not 7mm weatherby magnum

thankyou saddler
