Bottom eject semiauto rifle

Browning made a .22 auto rifle with bottom eject. Why does no one offer a similar type in a big bore model? or a shot gun? I would be especially interested in a bottom eject semi shotgun- like an automatic BPS or Ithaca 37. For reloaders, it would be an ideal set up to avoid chasing your brass all over the countryside. Is there some inherent weakness in the Browning design? Is it not economically feasible? Is there no market for one? What?

Where would the magazine go?

Even a tube feed rife has the feed mechanism in the way of a bottom ejection.

Magazine would have to stick out one side or the top. Most semiautos are based on a military design and military doesn't care about picking up brass.

Only bottom eject I know of was the Calico.

Good idea though.

wouldn't a bottom eject port tend to get full o crud when you drop prone in de mud?

have you seen the front eject tube on the FN 2000?

My Calico 900 spits the 9mm out the bottom, in BIG piles!

The FN P-90 is also a bottom eject rifle ... but no, you are just a serf and not allowed to own one.

Here's a video of one firing (look close and you can see the cases fall)

ah.. the memories...

My grandfather had a bottom eject browning when I was a kid (still have it actually)..

Seems as though every time I got to my 8th or 9th shot when I was really cranking them out the hot little .22 case managed to somehow find it's way down my shirt sleeve and resting on the inside of my elbow.. what fun, lol!

It aslo managed to malfunction on one occasion blowing bits of hot powder / etc over a good portion of my arm. Haven't shot it since probably never will again. It's just locked away in the safe for sentimental reasons.

If I had to guess I'd be willing to bet those reasons might be why you don't see to many :)

I still think this design would work in a larger caliber- but what do I know. Any input from an engineer?

well, if a Ma Deuce can eject through the bottom, it shouldn't be a problem for a sportsman's rifle, if you have no objection to a belt fed bambi getter.:uhoh:
A tube feed would likely be the magazine style, thus limiting your choice of bullet styles to two-round nose or flat.
One of the old Remington pumps had what was known as a spiral tube mag, which offset the bullet noses enough to where the bullet nose would not rest on the primer of the case head in front of it.
I don't think sportsmen would go with a top or side loaded mag-its either going to get in the way or look bad

I wonder if the "Bren Gun" version of the M96 Expeditionary rifle ejects out the bottom?

It could be done, but it would have few practical advantages and numerous disadvantages in actual use.

The magazine would get in the way if the gun were box-magazine-fed, although it might be possible to have the magazine angle in from 7-o'clock and eject at 5-o'clock (10-o'clock being the top.) The gun would also be subject to malfunctions when shot from low prone, having little clearence between the ejection port and the ground.

Actually, I was envisioning it in a tubular magazine, with blunt nose bullets, like .357 or .44 Mag. As far as getting crud in the bottom, I don't plan on wallowing in a trench with it for self defense- I have my Mini-14 for that. It would have similar applications to the Ruger 99/44 Deerfield Carbine. Also, I would prefer the non-military, non-"assault rifle" appearance.

I guess I'll just have to invent my own.

Even a tube feed rife has the feed mechanism in the way of a bottom ejection.Don't tell this to John Moses Browning or John Pederson. The Remington Model 17 and it's successors, the Ithaca 37 and the Browning BPS. These guns all do well feeding and ejecting through the same port.

No. The action would not get muddied up when you dropped down prone. You would have to take the trigger guard and not have your hands under the gun to get any mud in the gun this way. Who lays in the mud to shoot their guns? Even the best of guns would fail under this treatment.

Being left handed, this was high on my list of guns to get... I ended up buying a pump 22 though.. Still might want one later..

The FN P-90 actually is a forward eject weapon. If you look at the picture and take note of the hole below the barrel this is where the cartridges fall out of. The actually are not ejected from the weapon they more or less just pushed out by the empty cases behind them.

Bad Karma, you are getting your FNs mixed up. The P90 is the little PDW, it is bottom ejecting. The FN2000 is the forward ejecting .223 bullpup. It ejects into a tube and the shells fall out the front.
