Thanks for taking the time to read this, and i look forward to reading any comments.

I would keep the 2 Holland's and shoot the rest. Do ENSURE that you keep the 2 20 bores AWAY from your 12 bore stuff and your shooting clothing (unless you have a 20 bore gun, of course).

None of them are 20b...? but your not the first to say this... I post on FB and someone said the same thing ..

Thanks for the concern though, appreciate it.

As westley said with the 2 holland and holland the tracer and the one with the faded oliver name on maybe of interest to cartridge collectors

No problem, I just presumed that the 'Rio 20' was a 20 bore.

they'll be going on my shelf I think.. Thanks.

I’m strangely drawn to old cartridges 

Shoot em all except the rare ones, no point in keeping them have some fun!

If I am ever given the chance to go game shooting, I certainly shall. 

But most these loads are too large for the clay ground..
