Question gentlemen, our 2 1/2"shells over here are marked as 65mm but we also have shells marked as 67mm. Is it safe to still use them in a 2 1/2" gun? Is 2mm suddenly going to threaten the integrity of the gun?

Nath,
It sounds like the difference between a 2 1/2" shell and a 2 3/4" shell. That said, when I was a youngin and didn't know any better I shot a 3" magnum shell in a 2 3/4" shotgun. No harm was done that time but after I was told the difference I didn't do it any more. I would think a lot of it would depend on the strength of the gun in question and the power of the load.

Nath!
I would think it would MORE depend on what type of shotgun your using!
A 2.75" in a O/U or SxS might not be a problem as opposed to in a semi or a pump where the shell needs to be cycled through the action!
I would suggest trying to see if it fits the chamber and if the breach will close(gently- and outdoors-pointed away from anything!). If so, it shouldn't be a problem.
PS- no more knife pics! No fair teasing us Yanks! Remember WWII?
Besides, us Irish yanks still might bear a grudge over that potato thing!
Just kidding! Have a great w/e bud!

I had a guy I worked with that shot 3" out of his 2Â¾" gun semi-regurlaly. I don't think it is a good idea. I don't know everything there is to know about shotguns, but i have never heard of an advantage to doing so. Matter of fact I can think of a number of reasons not to.

Short answer: Don't.

I guarantee you it is safe to use 67mm in 2 1/2 inch chambers. The only thing to watch is the guns proof. If it is proofed for 1 ounce, only use 1 ounce regardless of the length.

Logic was saying the same to me 86er, thanks.
Billy Boy now I know your weakness

i beleive the 67 mm is the old 2 5/8" shell; and like 86er says it is okay in the 2 1/2" chamber. and i beleive most guns with 2 5/8 chambers do all right the with 2 3/4" shell which is the 70 mm , as long as loads are modest and equivalent.

Now I have a question.

Are shotgun shells measured at their loaded or fired length?

Rusty · Post by **Rusty** » Sat Feb 02, 2008 2:48 pm

Fired length.

That's where the problem comes in if there is one. The shell folds down and what doesn't fit in the chamber takes up space in the bore which also causes the bore to be smaller right at the start. It might just be theory but... do ya feel lucky?

Nath · Post by **Nath** » Sat Feb 02, 2008 2:55 pm

Yes Mr Miller, thats how you can load a 3" in a 23/4" chamber. I guess a strong gun can tollerate such a mistake due mainly to the ejecta being flexable as it passes the forcing cone with some case mouth in it. The modern trend of lengthening forcing cones probably help some what should someone drop a 3" in.

OK, thanks for the information.

Nath, my old Lefever 20 double shoots 2 3/4. Since 86er is a shotgun maker I would take his word on it.
Don't mind BillyBoy just keep the knife pictues coming.

Nath! Very sharp looking steel! Didn't you post some Bailey pics a while back? I collect alot of Cold Steel, Buck and Gerber. Almost makes me wanna start saving for something really knice!

It was good to tease you Billy Boy

Rob Bayley has not been going long but he has allready established himself a regular client base that encompasses the world with his most sales going to the States. Very individual desighns based on practical and strength but not heavy (unless you want weight).
I have known Rob from school and we shoot alot together. We was shooting roosting pidgeon last night on a cold wind on top of an old castle ruin! His desighns of knife have been tested on many deer amongst other.
I have one of his prototypes and it is a peach, the steel holds it's edge like something I have never experianced before but strangely easy to sharpen

Best wishes Nath.

67 mm can be shot in 65mm/ 2Â½ inch chambers but beware of putting 70/ 2 3/4 mm there.

By the way, old hotguns deliver the best patterns with fibre wad loads. Plastic wads pattern too tightly to be useful.

Old Shatterhand, you have kinder exposed me

I have to make a desision as to whether to trade in a .410 and a muzzle loader and I have desided to try and get from a dealer a side by side I remember he had in a year ago of english make with 21/2" chambers. I have stacks of fiber wads and cards and think a second gun to go with my Greener would be better. Will try thursday night(late opening at the shop ). My wife will be present as she wants to be there and contribute a wedding anniversary present

Wish me luck.

I don't know about the shooting the 67MM in the 65MM, it's I guess it's all right, according to the other posters, but would not shoot the 2 3/4 inch loads in the 2 1/2 Inch chambers, because pressures will spike up quite a bit, due to the mouth of shell opening up into the bore, then the wad has to compress to get out of the chamber. Same problem with shooting 3 inch mags in a 2 3/4 inch chamber, it's not a good idea.

That's true about the wads, but you can shoot the plastic wads in the older guns, patterns will be tighter and the gun might even kick harder. The real problem starts when you shoot premium loads, and trap loads in the older guns, because those loads are often designed for the newer guns with backbored barrels, and have larger diameter wads, so on the older guns, shoot the lighter, cheaper hunting loads and you will usually be OK. Some people get the forcing cones lengthened in the older guns, to compensate for the newer shells, but that is not always a good idea on some of the older guns.

There is also another issue on older side by sides, and even some of the newer ones. Some of the cheaper ammo, Winchester and some of the Estates ammo will give problems on the older guns, regarding ejection, and ever causing the guns to lockup and be difficult to open after firing. I have had this problem with my old L.C. Smith, my J.P. Sauer, and I have even had ejection problems with my Winchester 23's. Part of the problem is some of the cheap ammo has steel case heads instead of brass and will not shrink slightly after firing, like brass will, so they stick in the chamber a lot worse. And then on some of the same shells we were having trouble with the primers, because the firing pins were sticking in the primers and making the guns lock up, and difficult to open. It's definately an ammo problem, because on other brands and sellections, all is fine. Lately, I have found that the cheap Federal Walmart offering seems to work fine, and my guns open and eject those without problems. My brother in law was also having the same issues with an old orignal Parker he shoots and hunts with.
