doublegunshop.com - home Forums General Discussion DoubleGun BBS @ doublegunshop.com Low Pressure Question

I've always kept my loads [ in damascus or twist barrels ] under 7000psi, usually around 6000psi with no ill effects even in the winter. Is nitro dirty ? Not if you've shot black powder. The only powder that gave me trouble was 4756 and that was in the winter with 7/8oz loads in a 12ga. That was a poor selection. With light 12ga loads [ now 3/4oz ] I've used 700x, Red Dot, Clay Dot, and now Promo. Is the Promo dirtier - yes, but not anything that's too bad. Does velocity differ with low pressure loads - probably, but again not anything that matters. So what if it goes up and down by 6 to 800fps. At ranges out to 35yds what's the difference in leads- 4 or 5 inches. Big deal. At one time I was reloading for myself, wife, daughter, and granddaughter - about 40 boxes per week. Now I'm down to about 20 boxes for the wife and myself. I look for any savings there are and Promo is the cheapest powder and 3/4oz helps a lot. They break clay targets just as well as my old 1 1/8oz loads. Just my 2 cents. Paul

Powder isn't the only culprit. I've found that the CB-4100 12ga wad works quite well until it gets cold, then seems to produce a greater number of bloopers regardless of the powder.

Hi,
just bought a mec to reload 2 1/2 inch shells for an old damascus barrelled gun and wonder if you or nayone would have some recipes for 3/4oz or 7/8 oz to stau under 7000 psi?

any help would be appreciated.

thanks george

I should have mentioned the gun is a westly richards 1905 hammer gun nitro proofed to 3 tons
thanks

You can easily keep them under 5500 lbs. by using 7625 or Nitro 100 (and there are plenty of others) but stick to a fast burning powder. Start with at least one ingredient--hulls and perhaps primers (I would suggest AA's and Win 209s or Chedites). We can help you with the rest of the load.

George, if you are going to roll crimp them, any load that fits into a 2 3/4" folded crimp will work in a 2 1/2" roll crimp.

This is for a 3/4 oz. load. If you roll crimp, Remington hull (nitro, Premier, Gun Club), 16.0 grs. Red Dot, Rem. 209P primer, Claybuster CB0175-12 wad, velocity 1250, psi 6200.

7 /8 oz. load. Same hull, 17.0 grs. Red Dot, Rem. 209P primer, Rem. TGT-12 wad, velocity 1200, psi 6800.

The first recipe is from Clay Buster, the second is from the Alliant Site. There are more from both.

Forgot, you will have to trim the hull to 2 1/2"
