Re: My Rifle - UPDATED 12-11-10 (Pics)
So i got to the range today with my uncle, Match ammo in hand, Bipod off the rifle.
We got to the range, set up the shooting bench. Tripod rest with sandbag sitting just in front of the bottom metal. Sandbags and rear bag set up. Started at 50 yards to get a feel for what might be happening. 1st group ( bottom Left Target) Winchester Power Point 150gr. Was pleased with that, considering the previous. Only thing i had changed was the position of the rest, instead of using a bipod i was using the tripod infront of the bottom metal.
Switched over to the Hornady A-MAX Match 168gr, and shot the 2nd group (bottom right target) First hits were landing 1/2 inch to the right, corrected, and shot that group ( Shooter error? Maybe a little horizontal shift [1/8th of an inch?] caused by the 5lb trigger.) SO we moved the target back to 100 yards, i took a quick break and dry fired a few times, no flinch (been working on that for the past week +). First two shots are the two bullseyes on the top left target. I was feeling great! Match ammo + Different rest position, obviously that was the problem right? No...Shot a few more, felt great about them followed the fundamentals, sight picture, trigger, breathing, follow through, parallax etc. Everything was perfect. The shots (still top left target) started drifting right. My uncle argued that it was me, and i was pulling. I said fine, you try it. He gets on the gun and shoots the top right target group. Could be argued that its acceptable for 2moa Hunting ammo, but i wasnt convinced since i just saw that ammo capable of >1inch groups at 100 yards. So he takes a quick break, dry fires to make sure its not him. He then shoots at the corner targets, and the POI had shifted at least 5 inches, to 8 inches in some cases.
Heres some photo's i took and labeled to make it (hopefully) easier to understand.
So i talked to a guy at the range, He said with the horizontal shift its a bit extreme, but he believes its the flimsy stock contacting the barrel, and when the barrel becomes warm, it changes your POI. He recommended getting a rod that matches the diameter of my barrel, removing the gun from the stock, checking all screws for proper torque. Coat the rod with rubber cement and get some 80grit sand paper and secure around the rod. Then run the rod in the stock a bit to remove the contacting points. Or just upgrade the stock to a Aluminum bedded stock, and have a smith bed it to the rifle.
I cant, and refuse to believe that its me, Shooter error bringing the rifle 7 inches off POA. I plan on calling remington to see if this is an issue with the rifle. I doubt i will get anywhere with that, because they will most likely say that the only way to find out is to send them the rifle, in which they will shoot it 3 times get the same results i got, and send it back. I plan on getting a new stock soon, though i plan on removing the rifle from the current stock, and checking the torque on all of the screws.
Anyone else have some ideas on free floating the barrel, or any other ideas. Obviously ammo isnt the issue, Shooter error may be 5% of the issue, and the rest isnt the issue. The stock is probably the issue, and im beginning to believe that the action screws may be playing a part.
I am somewhat dissapointed. Murpheys law, if it can go wrong it will, and I always seem to get the lemon of the bunch.
/edit: All of these shots were taken without serious barrel cool down, so i think the heat of the barrel (which wasnt much) may play a role in the stock/barrel issue?
