Recently I picked up a like new stainless M77 Mk II .243 with Boyd's laminate stock, with an inexpensive Nikon ProStaff 3-9 scope. Very nice looking, and made with the normal Ruger "built like a tank" construction. The first range trip was a bit disappointing with "remanufactured" 100 grain from Wisconson Cartriges Co, Winchester 80 gr, and Rem CoreLockt 100 grain. I knew the gun was better than 3 inch groups at 100 yards off sand bags, but three more range trips, including Fusion 95 grain rounds didn't prove much better. So....I ran the archives here the other night and found a thread from quite some time ago that settled my problem perfectly. The simple answer was in fact what was buried in that thread....proper torque on the action screws. A couple of days ago I decided to check the three screws for basic tightness, then run out to the gunshop and check with a torque driver. The front trigger guard screw wasn't even snugged up, so I hand tightened with a screwdriver, and lo and behold the floor plate wouldn't lock in. I scratched my head for the last two days trying to think of how to correct the problem, thinking the Boyd's stock must have been a bit out of spec. after a hundred rounds of ammunition downrange, and a bit of disappointment, a tiny shim made from a plastic coffee can lid, between the front base of the trigger guard and the wood made the necessary difference. A quick range trip proved successful. I shot several varieties of 80 to 100 grain ammo again, and my last to three round groups were amazing. The Fusion 95 grainers shot two 3 round groups (seperate targets) that could be covered with a nickle, and the with two targets overlayed the 6 rounds could have been covered with a quarter. NJow I can confidently start the quest for the "perfect load".
