m_liebst, why would you not be able to put shorts in the magazine? It is tube fed.
My tube fed Marlin 39a is rated for short/long/long rifle. Same magazine design.
Now, round lifter I can see being a more significant issue. As would recoil spring weight/strength.
But, it isn't a verticle magazine like the 10/22 or the Marlin 795: it is a tube-fed magazine.
