View Full Version : 10-Gauge? Good LORD, help me!

All,

For some stupid reason, I want to get a 10-gauge double-barrel (http://evylrobot.com/?p=184) as a range toy, and I evidently like pain. At the local pawn shop, they have an Armsport Model 2700 goose gun with 32-inch barrels marked at $600.00. I pulled the barrels off and put a flashlight in the muzzle so I could measure the chambers with my tape measure. When I put the end of the tape measure at the near end of the forcing cone, it measured 3.25-inches to the end of the chamber where the shell rim rests. I read in other places on the interwebtron that this gun will shoot 3.5-inch shells, but that doesn't sound right. Wouldn't that be a 3.25-inch chamber rather than a 3-inch? I really want a 3.5-inch chambered gun, not a 3, and don't want to blow the thing up in my face when I put 3.5's in it. :eek: I need help from anybody that understands these things better than I do. Please.

I think that the chamber is a fired shell length with the crimp opened.

measure an unfired shell and see what i comes out to be. i dont think a 2 3/4 inch shell is that long untill its fired. i could be wrong though. that might be where your answer is

It is my understanding that a shotshell measurement is done without the crimp. It is also my understanding that the shotshell should have room in the chamber to fully extend before the forcing cone. If I'm understanding correctly, then a 3.5-inch chamber should measure at least 3.5-inches from the beginning of the forcing cone to where the rim rests against the end of the chamber. I could be wrong, from anecdotal evidence that I have gathered from the intertoobz that I'm trying to collaborate or refute. Heck, I'm going to grab my 12-gauge and the wife's 20-gauge and see where they measure out. I'll let ya'll know what that tells me...

A 12 ga. 3.5" shell of mine measured out to 3.055" using a caliper.

Standard 10-ga shell sizes are 2-7/8 and 3-1/2 inch. Seems you've been looking at a 10-ga 2-7/8" gun.

Shotgun shells are measured to their open or uncrimped length. The chamber must be long enough for it to open up to this dimension.

OGD, that is what I have come to understand about these things. So, does that mean that if I measure out the straight wall of the chamber to 3.25-inches, that it will not take 3.5-inch shells? If not, what does it mean? That it is an oversized 3-inch chamber, or that it is chambered for some esoteric 3.25-ish shell (metric size, perhaps)?

To that end, are 3-inch shells readily available, but I just haven't seen them? I don't want to get stuck with some gun that I can't buy ammo for. I would be willing to reload if it was hard to come by, but if I buy the thing, I'm going to want to get some ammunition and shoot it.

I've looked at ammunitiontogo.com, cabelas.com, and cheaperthandirt.com, and I haven't found anything but Winchester Super-X blanks in anything but 3.5-inch loadings for 10-gauge. AAAARRRRRRGGGGGHHHHH!!!!! It seems that if I want a 10-gauge gun, the search is still on... :mad:

This might help – or not, but take a look anyhow.

Or....
Knowing that it's a relatively useless cartridge size, negotiate the price way down and then have it re-chambered.

Zippy, that's a neat idea right there! I just got off the phone with my gunsmith. He said that he'd like to see the gun before saying that he could indeed rechamber it - something about the possibility of getting the metal too thin at the forcing cones if there's not enough meat on the barrels. I'm a regular at the shop in question. I wonder if they would let me put a deposit on the gun and take it to my smith to have it looked over and have the work bid if applicable... If I ask, the worst they could say is no.

Some of the old Super 10s (2 7/8" chambers) are great shooters. Some older 10s are strictly for decoration only.

IIRC, the Armsports were Spanish, when Spain made as much junk as good guns.

Long ago, I shot one a few rounds worth. Handled kinda OK, though ponderous.

Kick, with tailored 1 1/2 oz turkey loads, was manageable, but I handed it back to the owner gladly.

Were I looking for a 10 gauge 2 7/8" SxS for casual clays, ducks with a Bismuth style non tox load etc, an Armsport would be an OK choice, though I'd rather have an old Greener or even a Super Fox.

And it would wear the best recoil pad I could find.

As for ammo, Kent, Gamebore and BP carry 2 7/8 oz loads.

MEC will make most of their single stage loaders in 2 7/8 inch 10 gauge on order.

Some data exists for 1 1/4 oz loads for these that's easy on old guns and us too.
