I think you are talking about loading a magazine. I have to buy a magazine loader for the 22 so I don't rip my thumb. My hands are also not strong, so I have to get a loader. I had forgotten about that, but must do it. I have read about them, know how they work and had settled on one and think I saved that page in favorites. I'll do that tomorrow. Hopefully, those aren't sold out. I've got all the gun company pages in favorites. I always check CheaperThanDirt first, since it is the closest to me. If I lived where you do, I'd probably camp at their store. I've been there once.
It's not like loading an external magazine which is later inserted into the firearm.
I manage to knock a little bit of bark off my thumb every time I use a stripper clip with an SKS, so generally, I shoot one round, reload one round with that rifle for my main use for it (ferals).
Of course, if stuff hits the fan, the blood just lubes the action, and I'll take notes on the whining after the action is over.
