Mossberg 590A1 Shooting High and Right

First few times out, I did not pattern the gun with shot. However, I noticed slugs were hitting high and right. Thought it was just the slugs and vowed to try another brand.

But, finally got to the range to pattern with shot. At 25 yards with both #4 and 00 buck I achieved the same result: high and right. If I aim center mass on a silhouette target, most of my shot hits just above the target's left shoulder.

Anyone else had similar problem? Any advice.

BTW, I have a plain bead sight, so I cannot adjust.

OHHHH BUT YOU CAN!!!
Consider your eye is the rear sight and adjust your "mount' accordingly... To rule out "flinch factor", go shooting with a buddy and load each others guns... Using a snap cap cap or fired round "recrimped" randomly put into sequence as a "dud" and watch the other shoot...
A flinch will be painfully evident when the gun goes... CLICK

Also have others fire your gun and look at the POA/POI of their shots.

HogDogs is onto it - before you think it's the gun, have someone else try it. I would also try some light target loads to help rule out "anticipatory flinch". Besides flinches and bad hold point, check your eye dominance - quite common for it to be opposite of your dominate hand and can cause cross shooting
 
Yes, do exactly what hogdogs says. Before you blame the gun you should always rule out the shooter, the ammo, the magazine (if applicable), and the conditions.
 
Maybe you need to re-crown the barrel? ;)

Yes, +1 to flinch. I was a flinching machine, all of my shot cup holes in the paper were all over the place with bead sights. Now that I have a set of good ghost rings ( and I know what to expect with the gun now) all my shot cups hit right at POA.
 
vitesse9, if flinching is not the problem, is sounds like the gun does not fit you. The comb is too high & the cast is wrong for you. Both can be fixed. I have never found an off the shelf gun that fit me.
 
Do you think I should get an adjustable stock?

I think you try other ammo and have a few friends shoot it to see if the results are always the same. It is not totally out of the question for a mass produced gun to sometimes have the barrel bored out slightly skewed. so best to rule any gun possibilities.

Most of the adjustable stocks I have seen for your application only offer the ability to adjust LOP. IF cast adjustment is the culprit, then simply adjusting LOP won't really help.

Whatever is awry can be fixed - it just comes down to a cost/benefit ratio
 
1. Buy a set of Tru Glo adjustable sights

2. Take the stock off and shim for cast-off and raise the comb

3. ...maybe both?

"Cast" That is a slight angle left or right where the stock meets the receiver. The "shim" is the item that is thinner on one side or other to impart this "cast" but if the gun is like my 500, it won't work as the "nub" that fits the horseshoe shape behind trigger group won't allow it.

My M590A1 came with a canted front sight and the rear ghost sight was drilled and tapped way off center. Sold it not to long after I purchased it.
