Lowering POI on a shotgun at its limits of adjustment

I got a Devault 391, Elite conversion- with the rib all the way up and the comb bottomed out its shooting 70/30

the rib is 7/8" in the front & 3/8" in the front--if I lower it all the way the gun shoots 100%

Would like together the gun to shoot totally flat 50/50 for sporting clays

Looking for suggestions--

 

Time to bend the barrel.

Sell it and buy a bolt action JC Higgins.

 

Thanx for the help guys-looks like I'll buy a sporting 391-

 

If the gun has screw in chokes , you can get a tube to shoot where you want it , It will be a dedicated tube just for that gun . wrights did one for me and it cured the problem . Hope that helps .

 

If you like the Beretta and want an adjustable rib get the A400 multi target. I’ve got one listed on here For Sale. I had a Devault 391 conversion and this gun is close to that as far as a factory semi auto.

 

Will be calling Briley today, for one of their EXcentrix chokes

 

Might be cheaper and easier just to shave the top of the comb. I mean you're prolly looking at less than 1/8" and how big a deal is that?

just a thot

 

If you don't want to alter your existing comb, have a thinner comb made for when shooting sporting clays. ....Switch the comb back when shooting trap.

 

I'm sticking with this 391, has a release trigger & I have a complete receiver with a release in it, just in case something craps out

 

The rib adjustment does not lower you point of impact!!! The comb does. If it is an adjustable comb, you can take the comb off & sand some off the bottom of the comb with a belt sander. Then seal it with Birchwood Casey stock oil. If you only need to take a 16 of an inch or so off, don't even worry about sanding the bottom with the metal adjustment plate on. Don't sand into the screw heads. Your eye is the rear site. The rib adjustment is only for your site picture. You have to move the comb in the direction you need the point of impact to go. I have done it to several guns I work on with excellent results. Get the impact right, and then move the rib for your figure eight picture. Easy fix, unless you need a lot off the bottom of the comb, then you will have to take the hardware out & trim the wood out to properly reset the hardware.

 

If the front bead is vertically adjustable then moving it does change the POI if you shoot off the bead. Moving the bead is just like moving the comb but in the opposite direction. Simple geometry. Tilting the rib one way or another does change the view but does not change the POI unless the front bead moves relative to the bore as a result.

 

If my memory is correct - or check it out on Rolin Oswalts stock fitters bible -1/8 inch raise on the front bead, on a 3/4 ' barrel will lower you POI 3" -You will have to check it out - this is what I have done to several hunting guns to lower their POI - Works good - held on with two sided auto tape

 

Thanx guys-When Dennis made my guns for me, he told me the rib adjustment from top to bottom would be 70%-100%, without moving the comb--and what about those Krieghoff ACS's with an adj rib-think they do a little more than the sight picture

 

The bottom end ,the gun shoots 80/20--everything else goes higher

Briley will make an Excentrix choke & it will shoot 55/45--now the Big ?--its only $125.00/per choke

If you were going to shoot sporting, 5-stand & crazy quail
and wanted just one choke what constriction would be close to a fits-all

 

My thoughts are why try to turn a dedicated trap gun into a sporting clays gun. I’ve owned several of Devaults Conversions and the only one that would lend itself to sporting would be the Kemens he did. Even at that you would need the flattest rib he made.

 

I'm 77, got 3 dedicated trap guns-just trying sporting clays for s--ts & giggles--do not want to buy a dedicated sporting gun--really don't care for the sport-but its something to do and its 15 minutes away

Got 3 DeVault guns all made for me ,an Infinity, 682 Gold E & a 391 Elite conversion--never could shoot the 682

 

I’ve stayed away from sporting because I’m afraid I’d like it. Ive had 2 Kemens Dennis converted and wish I’d kept them. Dean Deboe has a Mach One I’d like to have but he is keeping it. I borrow it from time to time. Dennis knew what he was doing.
I’ve had one of Briley eccentric chokes, they work, I just didn’t trust that it would index correctly.

 

I've see some Kemens that Dennis worked , they appeared to be beautiful guns

 

Plan B, since I have a complete spare receiver, with a good trigger, bolt release--I've decided to get a 28" sporting barrel (new) and a used sporting stock and not have to worry about sending my DeVault barrel via Fedex,eta DeVault barrel is not replaceable if s--t happens

 

shot a browning BT99 golden clay yesterday -- I have the same question? Why would anyone build a gun with a adjustable comb that starts out at 80/20? -- Was it just that gun? or is there a market for a guns that can be adjusted up to three foot high? Great looking gun just can't live with that high a shooter to start with and no adjustment down-

 

My Trap guns all shoot above 80/20--I'm now talking about a sporting gun-if you are shooting @ a rising target why would anyone want a gun whose shot pattern was under the target

 

Many targets in sporting clays are dropping at the break point. Most misses in sporting are over or behind, so I sure don't want a 80/20 gun.

 

Thats why I'm going to plan B, waiting on the new barrel & furniture

 

Just did a customer Krieghoff that was shooting too high for him. Took the comb off & sanded the bottom so it would sit lower. Sanded just to the screw heads. Came back & needed it lower still. Took the comb off & took the hardware mounting screws out & drilled the holes a little deeper to counter sink them a bit & put screws back in. Had to sand a little off the front & back of the comb so it would drop all the way down. Looked real good. He was happy. He texted me back two days later & told me he won the AA singles with 100 strait soot balls. So lowering the comb did the job & he is happy as a clam.

 

This or a big bead can work beautifully to raise POI

 

When to the patterning board today--compared 3 guns:
1) the 391 I put together for sporting patterned 50/50

2)My DeVault 391 conversion which I will use for doubles only--patterned 80/20

3) My Infinity for singles & caps patterned 140

 

I just have to ask you a question. Please explain to me why raising the front of the rib wouldn't lower the point of impact? I don't understand your line of thinking.

I had the rib as high as it would go and the comb as low as it would go and todays patterning certified is was 80/20==this is on my DeVault 391

 

Think about it this way. If you had no beads at all on the gun, raising or lowering the comb would indeed change the impact. If it shoots high, sanding the comb would lower the impact. If you shoot rifle or pistol, the rear site is moved to change point of impact. Your eye is the rear site on a shotgun. Lowering the comb changes your rear site. The beads are merely for your site picture to get your figure eight. Works every time. Move the comb in the direction you need your shot to go.

 

There was no way I was going to sand a custom DeVault stock comb--I'm happy with cheap route I've taken

 

If the stock was custom made, the maker should have had you shoot a try stock for point of impact, and make your new stock to those dimensions. Otherwise, what is the point of a custom stock. The gun has to shoot where you are looking. Otherwise you can say what a pretty stock. Can't hit anything with it, but it sure is pretty.

 

My custom 391 was made for me shooting TRAP (10 years ago), played with it for sporting clays--didn't work

Was not going to booger it up for sporting clays--coobled up another 391 for sporting, will see if it works
