Check the receiver/barrel
There were several Mossberg .22 rifles that load through the stock. The 51M, 151K, ect. These have a removable inner rod that is draw back through the buttplate, and cartridges are inserted into an angled hole in the side of the stock. Mossberg also made rifles that loaded from a box type magazine, and an under barrel tube magazine. There are more than 100 different Mossberg 22 rifles made.
With the right loads and choke, yes
DO NOT ATTEMPT TO DO THIS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! DANGER!!!!!!!!!!!!!!!!!!!!!!!!!!! DANGER!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! DANGER!!!!!!!!!!!!!!!!!!!!!! UNSAFE!!!!!!!!!!!!!!!!!!!!!!!!!!! DO NOT DO THIS!!!!!!!!!!!!!!!!!! NEVER TRY THIS!!!!!!!!!!!!!!!!!!!!!!!!
=loads=
A Circle has an infinite number of lines of symmetry.
I'm Sorry But There Is No Exact Number Because There Are Loads And Loads!
Check the receiver, barrel, under the forearm
.45 is the caliber of the bullet. Other loads in this caliber include the .45-70 Government, .45-90 Sharps, and .45-110 (the caliber of Matthew Quigley's rifle in "Quigley Down Under"). 120 is the weight of the blackpowder charge, in grains. I.E., 12000 grains/1 pound.
45/70 caliber center fire. But NOT factory loads. For the trapdoor the case must be loaded with black powder

From Mossberg's website:"Can I shoot slugs or buckshot through a "smoothbore" field barrel with Accu-Choke™ tubes? (500/505/535/9200/88/930 models) Yes, and with sabots or rifled slugs, the more "open" the choke tube, the better the accuracy ("Improved Cylinder" recommended.) The "full" or "modified" choke tubes are preferred for buckshot loads. Slugs, buckshot and steel shot loads are not recommended for use with an extra full "turkey tube" installed, due to the tube's tight constriction. Do not fire any load without a choke tube installed, doing so will damage the internal choke tube threads. "
When you have multiple loads in a series, the resistance of the loads is added together allowing very little current to flow through the circuit to power any of the loads, making for a low amperage circuit. If you have your loads in parellel, the resistance of the loads in the circuit is subtracted which allows more current to flow, making for a high amperage circuit.
