Any advice for 2 1/2 in low pressure 12 g loads using Cheddite paper hulls?

[John Devin]

Brand new to this. I am looking for 2 1/2 inch low pressure 12 g loads using Cheddite paper hulls. I have found several loads under 6000 PSI for 2 3/4 inch Cheddite and Federal HOA plastic hulls and have loaded the Cheddite and used them in my 2 3/4 inch chamber Parker GHE. However I am hoping to shoot my 2 1/2 inch chamber guns. I have ordered 2 1/2 inch Cheddite paper hulls and am looking for low pressure loads using them.

Get the Advantages Manual from Ballistic Products. That is arguably the largest single source of data.

Are your guns true 2 1/2" chambers. They may be 2 5/8".

If your barrels haven't been messed with and are in good physical condition, I wouldn't hesitate to shoot 6000 PSI shells in them. 1/4" isn't going to raise your pressure significantly.

I will get the BP Advantages Manual. The other guns are English made shotguns. I and pretty sure they are both 2 1/2 inch chamber guns, but will double check. The 2 3/4 inch 12 g load (Cheddite plastic hull, Cheddite 209 primer, 16.4 grns Perfect Pattern, 1 ounce 7.5 lead shot, CB-6100 wad, 1/4 inch felt wad (under plastic wad) with an over powder card) shoots and patterns reasonably well in my Parker GHE. It is under 6000 PSI. Now I am looking for a low pressure load for the 2 1/2 inch Cheddite paper hulls. I will try the suggested manual...

Hi John, I would use the Perfect Pattern load you list all you have to do is use a trimmed 2 1/2" cheddite case then leave out the "1/4 inch felt wad (under the plastic wad)". You should expect the same performance as the 2 3/4".

The walls on the Cheddite paper hulls are, according to BP, .030, much thicker than The plastic hulls. I load CB 075,3/4 oz using CBs recipes in Cheddite paper. They load and shoot like a dream, easy on the gun, shoulder, and break clays with authority. Good shooting.

Amen John. That's all I shoot in 12,20 and 28ga. They are well worth the effort.

Thank you John P. What is your source of CBs recipes?

Which MEC or Hornady 366 Bushing drops 16.4 grs of Perfect Pattern? Thanks
