Loaded Wagglers

[peakoverload]

This is probably a dumb question but I've used loaded wagglers in the past which have said something like 2BB + 4 No. 4 i.e. it's loaded with 2BB and it'll take another 4 No. 4 to cock it.

I have recently been given a bunch of Preston Innovations Loaded Wagglers (some of which are HUGE and I'll probably never use) which say things like 6g 1g. Okay so I know that it means that it's loaded with 6g and it'll take 1g to cock it but what the hell is a gram equal to in shot?

Ahh just noticed that 'modern' shot dispensers also show the weight as the size. Hmm all my shot dispensers are around 15 years old and only show the size.

Maybe it's time I bought some new shot!

So it looks like 1g = 5x No.4
