I have tried a BUNCH of different loads for my 7 mag and the best i can get out of any of them is 1" groups, IT IS A WINCHESTER MODEL 70 LAREDO CLASSIC LR, IT HAS THE ALLUMINUM BLOCKS IN THE RECIVER [sorry about he caps] i would like to see if i can bed the recever? the barrel is floated but i dont know anything about glass bedding or epoxy bedding or where to start i do not know what kind of stock it is ,it is grey- blue with black specks in it, it is pretty heavy and has the wide forend .the barrel is a tapered heavy barrel with a muzzle break not adjustable it has the small holes all the way around the brake, any one know where i can start, i have been reading a bit on web sites but i need that first step or shove in the right direction.thanks.
