Anyone know what threads GR Douglas and Sharon uses for their barrels?

I have a 66 twist 36 cal douglas barrel and what im guessing is a 70 or 72 twist 54 cal sharon barrel does anyone know what breech plug I need to get for them?

usually depends on a.c.f. measurement. just measure the hole

I bought a 45 caliber Douglas barrel in 1980 that had a 5/8 thread for the Breech plug. So I would suggest that a 36 might have the same, but the only way to tell is to measure the barrel thread. Remember what you will measure is the root diameter not the od of the breech plug thread. Most hardware stores have a selection of ordinary bolts you could try.
