While our 10-round magazine always fit & fed in the 96/44(Ruger’s Lever-action 44 Magnum), spent cartridges would commonly hang-up in the ejection port opening, preventing being able to load ‘the next round’. Well, we had the time to look-over where exactly the spent cartridges were hanging up, and took to a trial an error approach, and turned out successful on the 2nd try. There is a seemingly purpose-less half-round channel in the top of the receiver which is where the rim of the spent cartridge was catching as it would try to eject. Our second attempt amounted to a 5/16″ brass rod, reduced to a half-round shape and pressed into the receiver channel — bingo!!
Spent cartridges no longer hang up while shooting when using our 10-round magazine.
Above you can see our first trial and error bit, the milled out area off to the right, which did not solve a thing; and to the left, the half-round brass piece filling in the channel, which now allows spent cartridges to eject free and clear.
As stated in the video, any first-time buyer of a magazine for their 96/44(Lever gun) will receive a free ‘brass adapter-insert’ to make ejection possible.
