There was a YOU TUBE vid of a fella shooting a 9 shot mag in the Ruger 96/44, I saw it like last spring, its since been removed by the poster and the guy not contactable, nobody has been able to find out who made it or how many there were, or if they were even for sale......so stuff of urban legind I guess
The first was the original that loaded like a pump shotgun and was a dead ringer for the 10/22 in a side by side comparison the bolt locks like a SKS, the model 77/44 bolt gun with detachable 4round rotary mag, next was the 96/44 leveraction that uses a 4 round rotary mag and locks up like the Kessler 56 levermatic 12gage shotgun its copied after and the 99/44 Deerfield that resembles .44mag version of the Mini-14 and uses the stock ruger 4 round rotary mag, ther was You Tube vid of a fella shooting a 6 round mag so I guess thers sombody making mags greater than 4 for the detachable ones.

The original (1960/1970's era) .44 carbine gas system is tap's off a nipple up front the mag tube and two action bars along the tube mag work the bolt and thers the bolt return spring around the mag tube, so stuffing any more ammo in that cramped space is a moot point.How to Disassemble, Clean, and Reassemble a Ruger 44 Magnum Carbine Semi-Automatic Rifle.

I had a 1972 .44mag carbine and I could only get 3 in the mag + one in chamber, It was a bear to thumb them rounds in the mag
