Cast on/off change


Recommended Posts

Its very easy, pop the recoil pad off and this exposes the only nut required to make any changes to cast or drop. To adjust drop remove the nut completly and slide the stock off and swap out the front shims you want for drop, these are indexed with letters like C, A, B Z indicating what degree of drop( cross refrenced in your supersport manual on page 84.


As far as adjusting cast, the back spacers are indexed with an SX and or a DX. SX meaning cast on for lefties and DX meaning Cast off for right hand shooters. I am assuming it is the rear spacer that is confusing you.


Which ever impression ( SX or DX )is twords the top of the stock when installed inticates the cast status.

For example If you have spacer lettered C ( 60 degrees) in the front and you want Cast off simply align the rear spacer so that C DX is on top ( twords the top of the stock where you can read it )and tighten down the nut. If you want cast on, filp it over where C SX is twords the top and tighten down the nut.

Each rear spacer has 4 differn't settings ( two letters indicating the drop amount, and the option to have those letters in a DX or SX configuration.)


Be sure to match both spacer letters.

Meaning what ever spacer you have in the front ( A,B,C,Z) make sure the spacer in the back matches that letter also. Like I said, with the but pad off looking at the spacer,you can read from left to right on top of the spacer what the current configuration is.



Oh and I forgot to add, that on the front spacer ( receiver side) there is actually two spacers one for drop indicated be a single letter( the A,B,C thing) and another one that simple says SX or DX ( its reversible and you just flip it over for one or the other) make sure that when you put your front spacer in that you put that front cast spacer in the correct position also

Thats correct, only cast on, and cast off with the factory shim set.

I guess you could "improvise" and add a little more wedge...

A good shotgun fitter should be able to tune any additional cast if you need it. They employ a highly technical process of bending stuff...

First I am not clear as to what "cast is". Never had a gun where there were options until now. Is it moving or "casting" the stock one way or the other? I'm a right handed shooter with a right handed gun. I guess my gun came with cast off? Any advantage for a right handed shooter to cast the stock more inward toward the chest?

On page 52 of the SBEII manual figure 52 it shows that #6 is the cast shim. I just got done changing the drop shim #7 (mine was B from the factory) to C. I didn't even know there were two pieces there at first glance, the cast shim was snaped tight against the drop shim. My question is this, what in the world does the cast shim do? Is the #6 cast shim just flat because it is a factory right hand gun? Coloradoryan suggested that the cast had to do with the way you installed #4 the locking plate. I can see how that might work being that the hole in the locking plate would be to the right instead of left. What is casting and which part does this? Is it a combination of both? Only one cast shim came with this gun there is no other option other than to flip the cast shim to the other side marked SX and I don't see what that would accomplish. I have asked plenty of questions now so take a shot at enlightening me.

It all depends on how the gun fits your particular physique ... you gotta get measured & then fit the gun to your measurements. (as mentioned by coloradoryan)



Seems to me the technical end of this has been well covered above. My two cents worth of advice ... If you can swing the cost, you would do well to bring a professional into the loop. If not; you could probably just try different shims, shoot; see how you're hitting or patterning; and keep working trial & error until the pattern is dead on everytime you quickly mount and fire. I think heating and bending stocks is rarely required, so I wouldn't give that a second thought. Either way, it's going to take a commitment in time and effort that few people are willing to invest to do it right. I'd venture a guess that well over 90% of the shotguns out there don't really fit the shooter. Manufacturers build them to fit the "average" adult male ... whatever that is (5'-9", 165lbs???) So, in most cases, the shooter is compensating and adjusting to the dimensions of the gun. That's often why a guy hits well with one gun and can't hit a barn with another brand ... one brand just happens to be closer to "his" natural fit. The gun should inherently point where you look when you swing it up to your shoulder. It's difficult to tell what you're doing wrong with a shotgun when you're missing; we usually blame our technique. Which is true enough, if gun fit was correct. If not correct; our "form or technique" becomes convoluted to compensate for the gun. Thereafter, if we don't make the same subconscious fundamental "corrections" we're automatically going to miss before our actual shotgunning "technique" even comes into the equation. You can imagine how difficult it is to be consistent or good with an improperly fitting gun. Something like a rifle that shoots 6" to the right at 100 yards. As long as I teach myself to point 6" left on every shot, I'll get by ... but in the heat of battle what happens??? We revert. LOL Which brings up another point that NOBODY thinks about ... RIFLES should point where we look too!!! (Scopes mask that need)


Anyway ... I'd say if you're one of the 1% that has a gun that fits ... you'll reap the rewards, joys, satisfaction and self confidence that comes along with it. And the investment you make now should last for many, many years of shotgunning fun. Good Luck.

You need to call around as it varies quite a bit... if you have a good shotgun dealer in your area they can refer you to someone.

Don't go to just any gunsmith, see a specialist that fits shotguns. A regular gunsmith is only likely to fit Length of Pull, take your money, and kick you out the door.... A true specialist will have you out shooting at patterning boards until its right. You shoud count on a couple hundred bucks by the time its over ( depending on what type of stock you have ).
