Try adjusting the pitch. Sounds like your butt pad is not making full contact with your shoulder pocket.

 

I wasn’t aware pitch would make the gun kick straight up pretty violently

 

As stated above, check pitch. Are you left handed? Right handed? Does your stock cast on or off for the shoulder you shoot from?

 

Right handed and not sure

 

Pitch. Either to much up or down can do that. For me a little down is ok but most people's guns have to much down pitch and whack me in the face. Others claim that down pitch does the oposite for them buy a pitch spacer and try both directions before fitting it.

 

What is your site picture? Do you have a nice even figure eight or do you have alot of space between the beads?

I ask because you say it's an MX8 which is typically a flat ribbed top single where as any of the common unsingles are much higher ribbed. Your stock may not be suitable for the barrel thus causing more smacl to the cheek.

I know when I start seeing barrel between the beads, it usually means the gun is going to bite me in the cheek.

 

Sight looks the same as my bt 99 looking down it. The lop on the perazzi is 14 1/8 and the bt is 14 1/2

 

When my shotgun is slapping me in my face, I have found to move the adjustable cheek piece further away and sometimes lower the comb so I am not pressing into the stock and comb so hard. I had to do this with my Precision Fit Stock and my Stocklock System.

 

Problem with my Clyde slide is the butt plate goes in and out with the comb

 

When I read the LOP, I wondered if you were a small person. As mg1polo said, start with increasing the LOP.

 

I’m 6’ 1”

 

To keep my CG's from whacking me, I have to put a 1/4" pitch spacer on them. Thick side is on the top (heel), thin side on the bottom (toe). It made any cheek slap go away 100%. I get mine through KickEze, directly. You will probably need a grind to fit pad while you are at it. Call them directly and they can help you with the math to get your LOP right.

6'1", 245, my LOP is right at 15" when I'm done with them. Comes from the factory at 14.75". The extra 1/4" is a huge difference. The gun fits much better and my mount, head placement on the stock is much more consistent.

good luck

 

So maybe a bigger issue I have is I don’t know what my length of pull should be

 

Another vote for pitch. I had a TM1 that bit me in the face. Pitch adjustment fixed the issue. Find a good stock fitter. Don’t sell the P Gun!

You can experiment by slipping washers between the stock and the pad to start the adjustment, I had to take mine to nearly pitch neutral. Once you figure it out. Have the right pitch spacer installed.

 

Also another thing to consider is this. I have shot pattern stocks from wenig (aka bondo stocks) and had no problem kicking me in the face. But when they made my final product all of them kicked me. I can't shoot cheek to wood due to the finish on guns. I have to shoot a soft comb or a cheek ez. It may not me bumping your cheek. It may be pulling it. Just a thought

 

Pitch needs adjusting. My MX8 and TMS were the same until we determined the proper pitch. Unscrew the recoil pad screws and place a washer between the pad and the stock on whichever screw(top or bottom) is required to correct the angle you need. Once you know how many washers measure the thickness of them combined and sand a wedge shape plastic spacer the correct thickness at each end and place it between the pad and stock. Wha-la! Cheap easy fix.

 

another vote for pitch. Needs shimed out on the bottom

 

More than likely that is going to force the shotgun into his face even more. I've always had to do the top out. You've been running the auto in the BW too long, time to go back to the good old 1085. lol

I agree with storeman. I'd like to see the stock

 

Unless your stock pitch had been modified from factory, I suggest you put washers on the top mounting screw of the pad and try.

 

On any recoil device where the recoil pad and the comb slides forward in order for the device to work properly the gun is supposed to have zero pitch.

 

Actually, doesn't the gun slide back, the comb and pad stay tight in the pocket? Glass half empty, glass half full, LOL. Zero pitch would be the pits unless there was zero angle between the top of your deltoid out to your pec. Or are you thinking parallel comb? And that brings up another issue. If it isn't a parallel comb, adding to LOP will slide his head back a bit on the stock and can change POI (so it would lower POI a bit).

We're all trying to help, but 10 minutes with an experienced coach or stock fitter would be vastly superior to our internet advice.

Make sure the comb is parallel, and it is not angled in toward the front. Align from the barrel and not the rib. The shorter LOP sometimes changes the mounting position in the shoulder pocket. Longer tends to go out further on the arm side.

I was speaking of parallel comb.
As most trap shooters use whether it’s a Monte Carlo or straight stock.
I’m not very intelligent of the words that you have choose to speak.
I think that we are both saying the same thing I believe.
Yes indeed the stock comb and the pad stays on your shoulder and on your face however the moving force of the recoil energy from the gun moving rearward has to be absorbed by something. Now wouldn’t it be logical to keep the absorbing device in a straight line with the rearward movement of the gun. Further more I have never seen a Perazzi MX8 unsingle trap gun with a sporting or field grade stock.
However I haven’t seen everything yet.
Yes you are correct in what you said
Somewhat!
If I might add that all of the makers of the type of recoil absorbing devices that he is describing will tell you that in order for the device to work best is zero pitch. Straight line rearward movement of the gun upon firing.
I just might be wrong about this but I’m using common sense as well as what I have been told by the makers of such devices.

Ok, the only reason I ask is that if it isn't parallel, then moving your cheek back will actually lower your eye. I didn't see where is says it's an MX8 unsingle, just MX8.

I agree they might have to be installed with zero pitch for proper function, but that doesn't mean you can't put a pitch shim under the pad to help the recoil be more evenly distributed against the shoulder.

 

your LOP is very short as stated

 

Griggs recoil redirector is the answer to your problem. They are great! I believe I saw one for sale on ebay recently.

 

Adding positive pitch doesn’t always do the trick, but I’ve probably seen it work about 80% of the time. Remember, without doing anything other than that, you’re adding to the LOP, which might be a part of the solution. Good luck with it.

Brianmonster199 - You state that you have a BT 99. I assume that gun does not hurt you. So let's try something. Lay the BT down on the bench. Carefully, superimpose the new gun over the old one. Use the trigger as the common point. See what the differences are and if you are going to try, make changes to get the new gun to get it to look similar to the old one. To check the pitch, remove the recoil pads and stand the guns against the wall. measure the distance from the muzzle to the wall. check the recoil pads - are they the same or at least similar. PS - make certain that you are not a right handed person trying to shoot a left handed stock

 

They are exactly an inch different. The bt is further away from the wall

 

Don’t listen to what any of these guys are saying. You really need to get rid of that gun. You will never shoot it well and you will always second guess how well you will ever shoot it. I will help you out, I will give you $100 and take it off your hands. Problem solved. I will even pay shipping if you will insure it.

Yours in sport,
Mike

p.s. Call in the next hour and I will give you $125.

Please look at the gentleman’s post.
I think is says unsingle.

Sometimes it helps when I put my glasses on .

 

What is pitch?

 

Alright I have a bunch of different spacers ordered and a pitch spacer. I’ll let you guys know if it helps. Thank you everyone for the help!
