I know this topic has been discussed before, but I'd rather not go and buy more cartridges if I don't have to.
When I'm out with my shotgun, I'd like to stick a couple of charlie cartridges on my belt (just in case).
In among my stuff I have a box of 36g 3's (looks like an old box) and a box of 36g SG from a time when I used them for target shotgun.
Which, if either would be suitable or do I have to go and buy something else?
Cheers.
