Accuracy Problem

I have a Rem. 870P model # 4903. I love the shotgun but it patterns four inches low and four inches to the left. It does this with all types of ammo. The gun has about 500 rounds shot through it. Other than accuracy problems the gun has not had a single problem. Any thoughts... ?

What distance is it 4 and 4? If 25 yards or so, no problem, If 25 inches, big prob.

Deviations like this are common. There's things that can be done, but we need a bit more info. Range for starters.

A suggestion, try shooting with your offside eye closed. This may be a case of mized dominance.

Opps, left out the range it is 25 yards. I spoke with Remington today they said I could send it in and they would take a look at it but 4 inches off at 25 yards was acceptable for a shotgun with a 18 inch barrel. I agree with them. I also called Vang Comp and spoke with Hans "a great guy to talk with" he said that his system would improve the accuracy but that I might need to send him the shotgun if accuracy was not acceptable. He would than bend the barrel for correct POI. But is 4 inches worth $235.00 :).

Hans does great work, but I don't think it's worth it.

Try this...

First, make sure your master eye and master hand are on the same side. Use the guide in the Shotgun 101 threads to find out. If in doubt, see if the Point Of Impact shifts if you close your left eye.

If all's well in Eye/Hand Dominance Land, try....

Remove the pad by using a Phillip's head screwdriver. Grease it slightly to not tear the pad up.

Carefully use a long flat blade screwdriver of correct size or a ratchet and socket set to loosen the stock. Remove it, and place a shim about as thick as the plastic off an old shotgun shell on the left side and another at the bottom of the receiver. Reassemble.

This'll move the impact center(POI) up some and right some. Fire a few patterns and average them out. If not enough up and right, repeat with a thicker shim. Make sure you've got everything snugged up tightly.

4" isn't much, but getting it right doesn't take a Rocket Scientist or a week at Purdey's.

HTH...

Thanks Dave, I will give that a try. You can buy a lot of plastic for $235.00. Of course that plastic would be in the form of shotgun shells. :)

YES!!!....
