9 inches low on first shot!
Alright, was at the range yesterday got dialed in at 200 yards with this gun, Rem 700 7mm rem mag, 26" barrel, B&C stock.
Yesterday I was getting 1/2" groups at 100 yards and about 1.25" groups at 200 yards. Very happy with that shooting 160 gr accubond handloads (not my handloads) from a proven loader that sells commercially.
So I got home yesterday cleaned the bore, oiled it up put it back in the safe. This morning I didn't have to work so I thought I would go back to the range and check 300 yards to see how tight I could get it. Started out at 200 yards first shot was 9 inches low and perfect left to right. I had to walk up to the target because I couldn't see the hole. Got up there and took a little bit to find because I never thought it would be this low. So alright, seems strange but I did forget to take the oil out of the bore so maybe that is it. Second shot 1/2 inch low and perfect left to right. Nice...this is going to be good. Third shot 3 inches low and 2 inches right...maybe it just needed a few to foul it up. fourth, fifth and sixth shots are in about 2 inches around the center but about 1" left. So close to where I left it yesterday.
One thing I did notice is the recoill was barely noticeable at first and seemed to build the more I shot. Not sure if this is normal.
So I moved to 300 yards dialed up 2.25 moa and first shot hit 1/2 inch below center perfect left to right. Next shot was 2 inches low perfect left to right, then it started to go right the next 6 shots were between 2-4 inches right and 2-4 inches low. I only shot a total of 16 shots so I don't think it was too dirty or fouled but not sure what is going on. Scope and mounts are tight I felt I was getting off good shots, no flinch or pulls or anything like that wind was light and variable. Not sure what is going on the first 3 shots of the day were all over, the next 5 shots were good at 200 and 300 combined then right and low.
Any Ideas, could it be the loads? How can I get 1/2" at 100 and 4" at 300 and center of group is about 3-4" off? I am not a professional shooter but feel I can keep it in a couple inches at 300 yards. Am I expecting too much?
I really want to start shooting long range and thought this was going to be the gun since it was a proven 1/2" shooter at 100.
Glad to here any opinions or similiar experiences.
