bore diameter

Picked up a 1 1/2 12 1903 3.11 unstruck weight 28 inch bore measure an even 737 all the way end of chambers to starting of chokes. Hypothetically do you think the barrels r shootable? I'm shooting it but want your input.

[Chris Travinski]

Only an actual measurement of the minimum wall thickness would tell you if it's safe to shoot. But in theory if a 12 ga. is supposed to be .730 and you have .737, then you will loose .0035" in wall thickness, not a big difference.

[Rick Losey]

I would agree - the wall thickness is the key factor

Calvin,

Those barrels are probably okay. If in doubt send them to me and I'll measure them inch by inch.

Maybe there is a member with a barrel wall thickness gauge who lives close or at least closer to you? Heck with all those pheasants you've got out there I'll bet someone with a gauge would visit you :)

Good luck!
Mark

If you're shooting it and it works, don't worry. UK rules require a reproof at .740 bore dia. You're under that. And min. wall thickness is .210 9 inches from the breech. With a Parker barrel, you're probably OK on that too. But as others say, a mic check will reveal all.

Still, if it works... don't fix it.

Best, Kensal

they sound fine to shoot to me...when it comes down to it calvin yall be the man that makes the decision whether you want to shoot it or not....but we had better listen to some of this good advice thats given us...i guess thats why we ask questions .... charlie
