Hello Shooters! I am new here, and this is my first post. My name is Bill, but I will go by Ridgerunner, or RR for short. I live in North central WV and enjoy hunting, flyfishing, trapping, and shooting. I spend a lot of time in the mountains of WV, and also hunt locally. No time like the present, so here is a question: I have a Ruger 77/22mag. I replaced the barrel with a match grade varmint taper in stainless steel (416). My gunsmith rechanneled the stock and did a full length bedding. I wanted it floated, but he talked me out of it. I did the manufactures suggested break in procedure. I do not wish to name the barrel maker, as I have not as yet, isolated my problem. The problem is very poor accuracy. The groupings (5-8 shots) are stringing, therefore I suspect a stock problem. I have sanded the chanel with a dowel rod, and reseated the barrel and action about 3 times so far. This moves the groupings around, and sometimes sends the string in the other direction (high right or high left) about 3" at 100. This barrel is quite heavy, and my question is: Do I have a seating problem or a barrel problem? Or Both? I have loosened and tightened the seating screws while firing, to no avail. Are there any other factors that would contribute to this frustrating situation? Also, I checked the barrel mounting allen screws. they are tight. Thanks for all replys. "RR"
