My Rifle was NIB bought by my Dad in 1954, & handed down to me, As he never fired it at all, I try loading in 4 rounds of 30-30 but have trouble inserting them into the Mag tube, I am going to order a new Mag tube spring, As I feel that the Original one in it may be week, or worn, I will let my gunsmith do it , As I am not a Gunsmith type of a person, I hope this will solve the loading of the cartridges much more easier etc.
