2 7/8" SHELLS IN 2 5/8"
 

I've seen all the debate about 2 3/4" shells in 2 1/2" or 2 5/8" chambers which I shoot all the time, but do you believe the same applies to the short 10? I picked up a lifter 10 on a No. 2 frame with Plain Twist but it has 2 5/8" chambers. All of my shells are 2 7/8" with about 7700 p.s.i. according to the chart. Shooting 1.5 ounces which I like. I know I could roll crimp but I've never had success with that and don't know of a 1/4" spacer for the 10 short kit.

Opinions? Thanks.

I'll get a picture for you- I put a 1/4 riser under my MEC 10's short kit, just a scrap of maple plywood I had around- just traced the shell holder and cut it out on the band saw- works fine

but lately I have been using the Ballistic Products roll crimper- i like the results,

p.s I might add the bores are larger than .791 where the choke starts so the bores are oversized from the usual 10 gauge measurements of my other 10s. They are big ahead of the chambers also. I'll need to get my pin gauges out since the Skeets gauge will go no higher. They have .030 choke in both but the thinnest spots are .050 on the right and .045 on the left and almost all over .050. Since this is not in the book I wonder if this started life as a 12?

Jerry. Is your gun chambered for the brass shells ( abrupt shoulder ) or the paper hull. One of our members tried using 2 7/8" hulls in a gun chambered for 2 5/8" for the brass hulls and it kicked real bad. Just my opinion but an 1 1/2oz of shot through a 2 5/8" chamber may be a little much. Paul Harm may be able to tell you more about it. He gave me the loads for mine.

Wayne,

Appears to be a standard chamber. No abrupt end to chamber.

Jerry I pretty much stick with using 2 5/5" shells in a 2 5/8" chamber. If it was 1/8" difference I might try it But 1/4" I don't think so. I may have to try the wood spacer trick. It would be faster than roll crimping.

The thin plastic hulls of today do little to restrict the shot column moving through the forcing cone. Sherman Bell disproved this myth of high pressure being generated.

The above stated, a short, sharp angled forcing cone can cause higher recoil! Ouch!

If you can, shorten your hulls or roll crimp them. Either will produce a shorter overall length.

I shoot 2 7/8 in shells through my 2 5/8 inch 10 gauge with the step at the chambers end. I only use this gun for sporting clays and an occasional round of trap so I keep pressure and velocity low. I have not found any noticeable indication of excessive pressure or recoil when shooting 1 1/4 oz. at 1100 to 1150 fps. I have also found that I get a nice gas seal at the chambers end when using slower burning powders like PB or Green Dot in the 10 Ga. I also roll crimp the 2 7/8 inch shells, and after about 2-3 reloads I trim them to 2 5/8 inches and put them aside until I am able to find my preferred 10 gauge powder ( Red Dot or 700 X ). I load these a little hotter since they do not protrude past the step at the chambers end.

JA the short kit works on any Mec jr. I load 2 5/8 for all my 10ga guns even though some are for 2 7/8 - don't like sorting them. Also it takes less filler wads in the plastic wad. But then I'm only loading 1 1/16oz [ for target shooting ]. Just the one spacer works for me. As said, you can make a spacer [ any thickness you want ] out of metal or wood and save the money. Good luck. Paul

I cut some Federals down from 3.5" to 2 5/8." Then I loaded 1.25 ounces in them.

I had purchased two roll crimpers before, one metal and one plastic. Stored them in the same bag. My first attempt at roll crimping on the drill press was such a disaster I gave up. So I tried again and screwed the hulls up.

Well I guess so, as I was using the 12 gauge roll crimper on the 10 hull. Left a pile of shavings. Neither was marked. Got the metal 10 roll crimper out and did fine. Now if the sun will get enough snow off the ground to play with them it will be great, but more on the way tomorrow.

I looked at my Steelmaster MEC and I may have 1/4 of an inch adjustment with the short kit to regular crimp 2 5/8" hulls. Never thought of that.

Sure wish someone would make a brass 1/4" spacer in 10 so I did not have to adjust! Better yet also make a 5/8" and 7/8" brass spacer so I could leave the MEC at 3 1/2" and just use the spacer at the stations, like they make for 12 and 20.
