T48 double barrel rifle

[Bill Hollinger]

Board, I would like to share two photos from our esteemed member RCS.

From RCS:

"Rifle was developed by Winchester during 1956=57 and chambered
for the 22/T65 duplex cartridge (22/7,62x51mm with two bullets). Weight was
11.8 lbs, total length is 43.5 in and barrels are 23 inches.

They call it the double barreled T48 but it would appear to me that it is something
on its own ! Robert"

This is truly a unique specimen of the experimental work performed in the interest of defending this nation. Many thanks to Robert for taking the time to email these photos to me and many thanks to his ever present contributions to this site.

Thanks Bill for posting these photos, this rifle was developed by Winchester during 1956-57. There are two bolts, two barrels and two 20 rd magazines and one trigger and one gas cylinder. The line drawings of this rifle had some information stating that two T48 rifles were used but it looks to me that this is a dedicated receiver produced for this project but could be wrong. The gas cylinder has a ball that will block the other gas port if only one barrel is being fired, if both barrels are being fired the ball will stay in the center. The weight is 11.8 lbs, length is 43.5 in and the barrels are 23 inches long.
The cartridge used is the 22/T65 Duplex (22 on a necked down 7,62x51mm case. Thanks again Bill for posting the photos

What roll would this have been used in.?

[Peter Laidler]

Same question as warpig but with the added questions of what on earthly planet were they on - or what were they smoking? If you want two quick shots, just pull the trigger twice. Same if you need FOUR quick shots........ Just pull it 4 times! If it's 30 rounds you need, then fit an L4 magazine. If you want a machine gun, then don't bother with an FN-FAL!

Diplomacy prevents me saying more............

with the added questions of what on earthly planet were they on -

Probably at the request of a high officer who needed to smoke something to chill out.

It reminded me of a story one of my Physics Professors told me in '61. He was working at the Springfield Armory during WWII. An officer assigned him the task of designing/making a 5 lb Garand. He said that he tried to explain the physics of recoil to no avail. A number of months later he had the rifle done. The officer took it out to the range and fired a couple of rounds. Returned it and that was the last anyone heard of that idea.

The designer listed for the T48 double rifle is Stefan K. Janson, who was Manager, Arms Research & Development Dept of Winchester. His name should be familiar as he was one the principal designers of the EM-2 (No 9 Mk 1). Before WW2 he was a native of Poland and fled to England.

Peter! I'm surprised at you! And you an engineer? Aren't you the group that asks, not "Why" but "Why not?" Seriously, it's not much heavier than my FN C1. Other than that, it promises to be just a bit over complicated for Immediate actions and stoppages, and maybe teaching mechanism...mag change in a pinch could be a bit*h too perhaps...no bayonet lug thank god.

I just have to shoot it anyway, the armourers get to fix it...after all...

An early iteration of what became the SALVO/SPIW concept I reckon. Get lots of bullets (or flechettes, etc.) in the air. Precision was well down the list of priorities.

It takes two! One 5" and one 16"!

[browningautorifle]

One 5" and one 16"!

Would THAT ever be sweet! The Sargent Major's would never be able to agree on which one should be used for drill. And THAT would be another problem...
