Just got back from the range at Little River.Checking sighting of my 30.06 and my sons' Ruger 77 Mk11 , left handed. Previously I had posted about this rifles misfires with PMC ammo. Today following Tim at McDonalds Guns I tried Remington factory ammo instead , paticularly as Tom has the junior hunt at Sunday Island in about a month.Fired 11 rounds without a misfire , last time with PMC 3 out of 6 misfired. The problem does seem to be the ammunition.

My m77 30/06 did the same, except with handloads as well. Tried win,remamd pmc ammo, always a misfire, soldit off. Glad your problem worked out fine mate.
