Arisaka charger clips

Here’s a question that’s been puzzling me for a while.

Lots of clips have holes in the springs, I presume for tooling purposes as they are too small to make any difference to the weight. Some Arisaka clips also have a hole in the base. This can range from the tiny;

to the slightly bigger;

Any ideas?


No hole means a 6.5x50sr clip.
Hole means it is a 7.7x58 clip.
But normally they are interchangable for use with either cartridge.

I am always interested in any British Arisaka chargers anyone has for trade.

Also British 7.62 x 54, 6.5 Mann or 7mm Mauser chargers.
