H&K SBE I

[ncquackersmacker]

Not to be rude but that is why I said what I did about the shims. The way I see it they have nothing to do with where the gun shoots just where it points. As for being six inches low, I could live with that just cover his head.  It is a shame that almost everyone with a HK SBE has the same problem. I really love my gun and do not want to have to switch for turkey hunting.

Well guys I have hit a road block...I tried the A and B shims after switching out the D shim and the POI has not changed...I have adjusted to rifle sights to the max up and down and still the gun shoots 6" low every time...I have no clue what to do...anyone have any suggestions before it goes on the market?

I just want to make sure I understand how you're shooting that gun. You do not have it clamped into a vise, correct?

You are shooting the gun with it mounted to your shoulder with your cheek on the comb of the stock?

If you add height to your comb, you can try just about anything, it will change your point of impact. (You could use a towel and some duct tape just so you'll see what happens.)

When you change the angles, the POI changes, since your cheek is tight against the comb of the stock and you are looking down the rib of the barrel or in your case through the sights.

You can demonstrate this most easily at a short distance like 25-30 yards with a full choke or turkey choke, by shooting at "big paper" at least 3 feet x 3 feet with a dot in the center of the paper.

I'd recommend that you just sit on the ground, like you would when you're turkey hunting, no rest, and aim at the dot on the paper.

Something has to change when you change the angles.

Thanks,

Allaboutshooting,
   Thank you for continuing in trying to help me figure this out...here is what I am doing...I am sitting just like you said at about 20 yds no rest with the gun shouldered just as if I was hunting...I am using a really tight turkey choke (in the 640s) and using tru glo pro series sights...the left and right POI is perfect...but I have adjusted to sights up and down all the way trying to get the POI to move...not only can I not bring it up but I cant lower it either (I just wanted to see if it would change at all)....every shot is about 6" low...i have never had this happen nor ever heard of it happening...the part that really puzzles me is the fact that the sights are not moving the POI....sorry for the long post

You may want to take those sights off. They might not have the adjustment needed to change it. Maybe even try a different load. I have had a problem like that with a 535 shooting an IC choke and Win extended using the Williams fire sights. I change loads and bingo. I have also seen where the choke doesn't tighten up square. A freind of mine had to put a thin brass shim in between the choke and barrel on his Extrema to move his POI because the choke didn't tighten up square with the bore.

Hey guys, Well I can attest for ahaga's problem here. I'm his brother and if not for his patience i would have thrown this gun over a brush pile by now. I got a different choke to try this evening and some different loads to play with. We'll keep ya posted. I can't for the life of me figure out how a gun shoots the same POI from shooting it with just the vent rib and bead, to putting on a set of TruGlo pro series sights adjusted max both ways and tring 3 differnet shims no change what so ever.

You're welcome. I know how frustrating it can be when a gun just doesn't want to do what we need it to do.

If you have the rear sight mounted (on the rib) near the receiver, let me suggest that you move it so that the front of the rear sight is 15" from the rear of the front sight. Do everything else just as you've been doing it and see if that will change your point of impact.

Thanks,

As a follow up to my low shooting SBE (almost a foot), after trying every shim available with no change in POI a finally got drastitc.  At my wits end I decided to use the forked tree method.  It did not take very much pressure a I really did not feel like I done any thing but the POI changed to dead on.  After 5 shots at everything from 10 to 40 yards I was more than pleased with my adjustment.  Honestly, I wish I'd bit the bullet a done it two months ago.  It would have saved me a good amount on H-13 shells.  I would still use this as a last resort but when all else fails it is an option.
