doublegunshop.com - home Forums General Discussion DoubleGun BBS @ doublegunshop.com LOADING Pb in 2 7/8 10 ga?

Using the load of 25 gr of 7625 in my 12's and
20gr.of Pb in my 12's I decided to use the ratio which
is 25/20 or 75%. Using that I come up with 80% of 7625 which would give me 25.5 gr in my 10's or about 20% less. I think I will start with 24 gr and work up.
As a confession, I mistakenly loaded some 32 gr.Pb instead of 7625 a few years ago in a 10 ga that I had and noticed it kicked somewhat more before I discovered my mistake ,but nothing terrible happened.So 24-25 gr here we come.
As a matter of interest, 20grs Pb with 1 1/8 oz in a 12 ga AA hull is only 6300 psi
Thanks for the help

If it's of any help, Lyman's 5th has several PB loads listed for the 3 1/2" 10 ga. All 1 5/8 oz loads. Pressures range anywhere between 8500-9800 psi. Charge wts are 32.5-36.5grs. It would seem you are pretty safe where you are starting out.

Stallones,

I have used 24 gr of PB as my exclusive load for 1 1/4 oz 10 gauge loads for over 8 years at the Vintage Cup. I use a SP-10 wad with a nitro card underneath for roll crimped 2 7/8". If you are fold crimping, skip the nitro card.
When I load 2 5/8s for my old Boswell 10 hammer, I use the same wad/shot but drop the nitro card (still roll crimping).
This load has won a few times in 10 ga events and it is easy on gun/hull.

Thanks Joe, That fits in with what I was hoping. I am guessing that load is about 6000psi from what I can extrapolate.
That will also solve my cold weather ignition problems from 7625.

Joe I have a couple nice load using Solo 1250 using Federal plastic and Winchester paper hulls trimmed to 2 7/8th inches but unfortunately Solo 1250 has been discontinued. What hull(s) are you using and what is the velocity and chamber pressure for your PB ounce and a quarter loads?

Joe:

Do you need a filler in the SP10 wad with the fold crimp, or is the 1-1/4 ounce load sufficient to fill the shell to allow a good crimp? I've been looking for a 10 gauge, fold crimp load for my I. Hollis hammer gun (damascus) and yours looks promising, as I've already got several hundred Federal hulls from RST loads and lots of PB from reloading for a 12 gauge damascus barreled Thomas Turner.

Thanks.

sherman bells article calls for a 16 ga 1/4 in nitro card inside the sp10 wad.i use that wad in my lc grade 2 and 3 10ga.loaded on a mec 600 jr 1 1/4 shot.it crimps great on rst shells with the card wad in bottom of shotcup.

I tried the 16 ga filler inside the wad. I ended up with the nitro card on the powder, then the SP-10 wad atop. The advantage for me is that most of the shot is inside the protective petals of the wad and suffer less shot deformation/leading.
If you are fold crimping 2 7/8", just leave out the nitro-card. I used to put a card-over wad before fold crimping, just to be sure nothing slipped past my crimps. Those Federal 10s were tough for me to keep closed.
I have never looked back since switching to roll crimping. It was a long wait on ebay to find a vintage Lyman 10 roll crimper.
Remember, you don't have to be married to exactly 2 7/8" it can be shorter if necessary.
I usually shoot my Fed 10s 2-3 times at 2 7/8" then shorten them to 2 5/8" for a last couple of loads throuh my old Boswell 2 5/8" 10 hammer, ca 1878.

Hey 40x,
I have a Thomas Turner damascus 12 with scalloped stock. 5 3/4 lb with 28" bbls. It is a quail killing machine. Don Amos, Mr. MOI measured it and proclaimed it to be dynamically identical to a 2" game gun. I corrected Don's statement. My 1894 Thomas Turner lightweight predates the 2" game gun by about 35 years. So the correct statement would seem to be, the 2" game gun duplicates the weight and handling qualities of a Turner lightweight.

Joe

Joe:

Is the lightweight the Turner with the stock hollowed out? I am not describing it well, but I've seen photos of a couple. Looked a bit odd, but apparently got a good bit of weight out of the butt.

Rem

I'll post some Turner photos in a new post after I get home. Yes it is a really pretty piece of walnut scalloped out to about 1/4 thick. There is a heal plate to help strenghten the butt. The button is on the top of the stock.
