Jack,
Thanks. I understand the 20s may have higher pressure. But the lowest I can find in loading data is 9000 psi for a 7/8 oz. load. Even higher for 1 ounce obviously. For a 20 damascus with .028 thick barrels I believe I would like lower pressure. There has to be something lower out there. Jerry |

Jerry:
A lot depends on where that .028 inch of thickness is. What do your barrels measure nine inches from the breech? That is where they need the most metal. .028 at the muzzle is not much of an issue. |

John,
These are .028 at their thinnest spot 2/3 way down the barrells. Excellent bores, .027 choke each barrel so add .0135 to the thickness at the chokes, .615 bore, never refinished outside or honed inside, 0 frame, not cut. I'm not concerned with their safety. They have been shot for 110 years. I just don't want 12,000 p.s.i. and want to load my own for $5.00 a box instead of $12.00. |

Loads
Alliant Powder web site has some low pressure loads. The 20 ga. 3/4 oz. loads are 7200 lbs. with 20/28 powder and 8200 lbs. with Unique. There are others slightly higher.
I am using them. |

I have a load from a Woodcock Minnesota mag.: Rem hull and primer, bpsg20l wad, 17 grains Unique. 3/4 ounce shot. Pressure 7800, velocity 1225. I have not tried this load but I'm loading a 16 gauge load from same article. Hope that helps. Jim P

I am at my cabin, and away from my loading manuals, but look for loads I
using 800X. Not sure there is a lower pressure powder |
