Going to the range can be entertaining, educational, and often cathartic for folks for various reasons. In the case of a recent trip with a friend who wanted to learn more about firearms, the education proved to be reciprocal.

A brief explanation of the term “rimlock” for those unfamiliar with rimmed rifle rounds, first.

It could be safe to assume that, since one doesn’t merely “happen” on a blog devoted to milsurps by complete accident, that the reader understands that rimmed ammunition, like the .22LR, .303 British, and 7.62x54R all have that distinctive rim at the base of the cartridge. Since the latter example is what I frequently fire and the topic of the following post, “rimlock” (or “rim lock”, depending on your source) occurs when the rounds are loaded into the magazine in such a way that the rim of the topmost round in the magazine is behind the rim of the round beneath it. Operating the bolt forward in such a condition is almost impossible due to the firm conflict between the rounds and generally has been resolved by rubbing the exposed round forward with a thumb until the rims separate. I emphasize “generally” only because there seems to be other methods of fixing the problem quicker, like tapping the bolt a bit; however, since I have yet to experiment with any other alternatives, I can only write from experience.

Also, consider this a warning about following the link describing an out of battery discharge – the pictures are somewhat graphic.

Inspecting the setup of the ammo.

I’m not yelling. I’m emphasizing a vital point of safety…
Remember that post floating around about the out of battery discharge a while ago? Yeah, almost happened to me today.
I cycled a new shooter through the collection ending up with “Kukushka” with the normal routine of safety, familiarization, dry runs with snap caps, and then onto live ammo for all the weapons out there.
She was doing well, but then the complacency of comfort set in for her. She had a slight case of rimlock, rubbed the first round forward (and into the chamber) and started to cycle the bolt, stripping the second round off into the (occupied) chamber. Luckily, I was sitting over her and stopped her before the inevitable primer/nose interaction. Ejected and extracted the rounds, explained the possible outcomes of that situation, and carried on for a good rest of the day.
….Which reminds me, I need to refine my range first-aid kit to include for that situation.
