930 jm recoil

[blindman]

Took my 930 out for the first time today and thought it was kicking pretty hard. Some of my other friends tried it out and said the same thing. We had a 590a1 there that has less recoil. We shot slugs, 00, and #8. I'm a bit concerned as the jm is supposed to handle recoil better. Is it all in my head are is there something wrong? Gun was working fine other than being a shoulder killer

I cut down the length of pull and added a limbsaver pad, recoil on the gun isn't bad at all now, here's a link. http://www.brianenos.com/forums/inde...pic=203088&hl=

Its not in your head, but in your gun mount.

Does the JM Pro come with a shim kit? If it does, see if you can get a professional to help you adjust it so that it fits you properly. Shotguns are brutal if you don't mount them correctly or if they don't fit you well. They will slam and bruise you, especially if you shoot a lot or go for high powered shells.

I speak from personal experience. When I first got my shotgun and started shooting trap, I'll frequently get bruised cheek even when using target loads/bird shots. And when I tried some 3 inch magnum 00 buckshots, they felt like they were designed to launch a payload into orbit.

After learning how to mount my shotgun correctly, the bruising stopped and 3 inch magnums, while still punishing, are at least somewhat fun now.

I have shot the JM pro

It iwas a heavy gun with the 24" barrel.

The gun comes with the shims and spacers to adjust the stock to fit your body type and any higher mounted optics.

It should shoot softer due to the gas system and weight.

The 590a1 does have the steel trigger and heavy mag tube so the weight might be similar.

Fitment is everything.


But usualy auto loaders are softer shooting than pump and break action type guns. Work with the shims and make it fit you. Mine doesn't fit me , but still is much softer shooting than my 870 that fire me very well.

After a while the 930 and mossbergs do sore my shouldure too. But the recoil pulse is noticably softer (930). Again work on fitment. Should go a long way.

thanks guys.

mbiker - i'll take a looking shortening the lop. just afraid of screwing it up. also, the pad screws into the jb weld?

[Mbiker_101]

Correct, the limbsaver now screws into the jbweld.

Here's a quick guide to what I did to both my jm930 and spx

1. Disassemble buttstock, pay attention to recoil spring tube length.
2. Cut stock with chopsaw. No more than 3/4" due to recoil assembly.
3. Fill edges with jbweld to give screws something to bite into. Also helps and weight to buttstock to balance weight.
4. Cut recoil tube nut in half, needed for clearance.
5. Drill hole in limbsaver for recoil tube.
6. Drill pilot holes for limbsaver screws
7. Assemble

Shogun fit as others mentions help tremdously, now I can square ip to the gun and drive it better with very minimal recoil. I can shoot a steel match of 250-300 rnds with no problems at all.

i'll need to figure out how to cut the nut in half. wouldn't it be easier to swap the spacer for a washer to reduce the overall length of the nut+spacer?

[Mbiker_101]

True but the spring retaining pin is held on with the nut, but feel free to experiment. I used a dremel with a cutoff wheel, took 5 min to get nut in half. Tried to find a thinner nut but gave up.
