10ga loads ? - Page 2

J.B. Books · 07-30-2012, 01:07 PM

Most 10's will be around .750 at the choke/muzzle, take a .785 bore on average with 30 to 35 thou of choke will get you there. The wad is plastic under great force, it's going to give rather easily. Again a 1 ounce load at that velocity is incredibly tame and it should not be causing the gun as you say to be jumping out of your left hand and make you sore after 50 shots, especially at 9 lb weight of gun which brings it down to 10.71 ft lbs of recoil. That's about the same as a 243 Winchester. I think it's safe to say it's not because the wad is too thick for the choke or many of us would be experiencing the same problem.

Just shot two shells with 19.4grs of 700X, paper wads, and 1 1/16oz of shot - felt nice. I know the 19.4 is a little high for the SB loads, but his weren't with paper wads so I went up about 10% - should be safe. Bores were a bit dirty - maybe a 1 1/8 of shot and/or a bit more powder. Paul

I'm at a loss to explain it. A 12ga wad is even harder to push through a full choke gun. I still think it has something to do with the wads. When I open a shell, dump the shot, and then try to pull the wad out I either can't or it's so hard I ruin the wad. Not so with my 12ga shells when I goof something up and take them apart. My gauge bore won't open up enough to check the 10ga shell internal diameter and my shorter dial gauge that will is over to the club. I'll get it and check the shells ID. I'm about ready to pull the shot out of 100 shells and shoot the wads out and start over. I blew up a 1889 Remington by loading 94grs of PB when I thought I was loading Pyrodex - I kind of know all about the signs of too much pressure. Graig from Circlefly doesn't like 700X for low pressure 10ga loads. Someone told me he has a pressure testing machine and he got spikes in pressure using 700x. Not sure if it's true - maybe call him and ask. Paul

Ok, talked to Craig. He doesn't have a pressure machine - sends his testing to Tom Amhurst. Didn't know anything about 700X. What he uses is 7625 [ 38 Mec bushing ], Rem wad with a FIBER wad cut to about 1/4" inside the plastic wad for filler and 1 3/16 oz of shot. 6100psi at 1200fps. Tom told him the fiber cushion wad was better that a hard card. It lowered pressure and stopped pressure spikes. Said it was one of the best loads he had ever tested. Also said paper instead of plastic wads doesn't mean you can go up 10% with all powders - just some and didn't which ones. So I guess I'll just dump the shot and shoot the wads out of 100 shells to be on the safe side. Buy me some 7625. It's been a learning process. Paul

Craig said he was using the Rem wad and hull so there goes that idea also. Paul

hi paul, i shoot the same load out of my 2 frame gun at 8 3/4 lbs and the loads are just fine, you should be able to hold the gun with one hand with out dropping it. out of my 9 lb gun its is nothen. something does seem wrong with the load if it jumps that much. 700-x should have little flakes of yellow in it. does yours? keep us posted. scott

Paul, I had the same problem with a 2 5/8 chamber 10ga. It wanted to jump right out of my hands. It was really tough to hold on to. At the time I could only find Sherman Bell's loads. His hunting load made the bad recoil. I just switched to his target load at 4800 psi and it worked fine. Like BIG Friend Ten said, it had something to do with the sharp step at the end of the chamber. For lowest pressure loads, it was okay. I've since sold the gun.

It was 700x - I've ben shooting it for quite a while in my 12ga. I'll get a pound of 7625 and try it. I had even tried reduceing the shot to 1oz counting the 16 wad. No help. I really like the gun - hate to sell it. Paul

Forcing cones...

Paul Harm · 08-01-2012, 10:44 AM

Dave, I wouldn't rule out the step at the end of the chambers. I've cut all my shells to fit the chambers so that shouldn't be a problem. The step in my gun is very small - I'd have to guess it was intended for brass shells. I believe some call a gun with chambers/step a " chamberless gun ". There are no forcing cones. The bore is the same size as the inside of the shell. It would seem to me there'd be less recoil. But then again I could be wrong and there's something else to guns with stepped chambers causeing more recoil. Paul
