The Lyman 3d edition shotshell handbook has 2-7/8" 10ga load recipes.

Thanks Richard, I found that info and it's on the first page of my spreadsheet on the thread below. If you know of any other sources please send them along and I'll update it.

Mr. Forge:
Allow me to let you in on a little (very little) secret: The legal adversity to Damascus barrel guns in the US is exclusively due to early 20th century advertising bull pucky. You probably know this by instinct.
But -- as a professional advertising BS artist for almost 30 years -- I can tell you that the aversion to Damascus barrel guns was a scam to instill fear in older technology so the gun companies could sell more. and cheaper, fluid steel barrels.
Once this glorious BS was accepted as fact (like global warming) it was codified by junk science and became a foundation for legal precedent.
Nobody much cared about the UK's position and experience with the same metal compound.
Thus, you are unlikely to get any clear answer from any corporation about "safe" Damascus loads. They are too fearful of liability based on junk science -- and advertising BS.

Best, Kensal

ive shot a many of a heavy loads in these old unsafe barrels....only barrel i ever had blow up was the new fluid steel barrel.... charlie

The heaviest loads I shoot in any gun I have are put through my 1883 0-grade twist bbl hammer gun and I have no worries whatsoever about it.

how heavy are the loads richard that you shoot through your gun... charlie

I've put a lot of 3-3/4dram, 1-1/4oz loads through it and even some 1-1/2oz magnum loads with no issues so far. It has stout bbls.

I've heard of one fellow putting steel shot through a damascus Parker with more than .040 chokes - been doing it for years. So much for nothing more than a Mod choke. Paul
