This is way off topic because I am asking for advice on J-bullets! Whats more, advice about factory ammo! But since most of the shooting knowledge in the known world resides here this is the best place to ask!
A friend of mine has a semi-auto Ruger 44 carbine he bought back around 1980. He is not a shooter and hasn't shot it in years. He wants to start shooting it again and is looking for ammo advice. He tells me this carbine would not reliably cycle with factory 44 Mag ammo and that these carbines were notorious for that. He first asked me to load some ammo for him that would cycle the action. I know nothing about Ruger carbines and ultimately we determined he would be happier to just be able to buy off the shelf ammo for it. I told him there is a much better selection of factory ammo available now than there was in 1980 so here is the question:
Is there a current factory 44 Mag load that will make his 1980 Ruger carbine work?
