yeah they look like home loads, as I doubt proof loads would use keith SWC but there are stranger things. there were around 20 of this 2nd bullet type, which looks a lot like a 455 webley bullet scaled down. I got given about 300 of these SWCs in norma that are all knurled.
the rest, is a few hundred of geco branded ammo in geco boxes, which all looks to be factory. all is in RN, the primers are different to the norma loads, and the cases are slightly tarnished, not bright like the norma cases.
I'm going to pull a sample of all and see what's what.
If I can recognise the powder in the norma cases I'll see what sort of load it is. if not, I guess it is all for the bin.
