20 gauge Sterlingworth with straight stock
Re: 20 gauge Sterlingworth with straight stock
.603 and .608 must be the muzzle measurements; not the bore. Bore should be between .615-.622.
Don't just look at the drawing, READ!

Notice, here it says .025 at 9". Most guns that have .025, it is found about the middle of barrel length; 14-15" where pressure is less than at 9". Guns have been used with .018 at mid barrel. If the bores are good on the gun you are considering, I would'nt worry about .025 at mid-barrel.

Here is a nominal pressure chart for various powders, one is black powder. As you can see, even at 9", pressure has dropped considerably and wouldn't be much less at 14".

"There is greater pressure as the gauges go from 12 to 16 to 20 etc. therefore the minimum values might increase."
If this is true, and the gun I'm considering is a 20 gauge, then isn't .026 as one of the barrel thickness measurements a bit on the thin side?

Re: 20 gauge Sterlingworth with straight stock
Max pressure for a 2 3/4" 12 is 11,500; 20 ga. 12,000 which is minor difference. Did you read on the Gibbs site. Their testing perameter is for 12 thru 28 ga. for .025 thickness.

Yes, I was just reading that. Thanks for your timely response. I appreciate the link.
Re: 20 gauge Sterlingworth with straight stock
OK, I can't seem to come to terms with the look of the current stock. I guess I agree with whoever said it looked like a canoe paddle, or it wasn't "foxy" enough. The seller will let it go for 1,600-1,700, but then I'd need to restock it. Won't that set me back 2,000 or so?

Re: 20 gauge Sterlingworth with straight stock
Did you ever look into the .603 & .608" barrel diameters? That sounds like the chokes, and with only .005" delta between the numbers, it's likely one of them was opened up. Possibly both. If that's the case you'll want to be sure it was reamed on the bore axis so that barrel doesn't "shoot off".
Seems like if the gent reported the wall thicknesses, he would know what the bore diameters are.
Regarding restocking, it depends what you want but a TOP SHELF stocker, ACGG level person who is in the business and has a FFL, is going to charge 3-4k plus the cost of a good blank. Silvers

Re: 20 gauge Sterlingworth with straight stock
I'll add my two cents here. If you don't want that gun for $2500, PM me with the seller's contact information and I'll buy it.
Re: 20 gauge Sterlingworth with straight stock
It could be worth it to someone. If I were in the market for a 20ga SW and this one suited me to a "T" , I might pay that much.
