Hello, I am brand new to this forum and am looking for some opinion to those more experienced than I am. I have an R1 in 30.06, and it is well sighted in and hit 1 to 1 1/2 inch groups at 100 yards. Love it. But, I just bought a new R1 in .300 Win Mag and can't seem to get tight groups. I tried Fed. Coreloct, the Winchester Power Point (if I recall) and some cheaper ammo., all 180 gr. I get 5 to 7 inches high for a few shots, bring my scope down, and then low or back high. I have put perhaps 60 to 80 rounds through it, cleaned and cleaned and still no consistency. The first shot is always high, then I hit close to zero, then the floaters again. The inaccurate shots always vary up and down. I have a new gunsmith installed brake on it. Is this a break in issue, shall I got o 165 gr., shall I keep shopping around for better ammo fit? It seems like the longer I shoot, the worse it gets--is this a hot barrel? Any advice appreciateg--thank you!
