If you order from Century by the pallet, they will send it in the crates. I need to install the new parts on my Maxim 08/15 and test to see how each type of 7.62x54r works in her. I think some will shoot faster than others, with some having extractions problems. This is how it was with 8mm. Who wants to go blast a few thousand rounds with me in the name of science?
You have a better chance of going with me if you are a woman between 30 and 40 with a knock out figure.
30,000 HB Bulgarian brass cased
90,000 LB Bulgarian brass cased
4,000 or so HB Hungarian I think brass cased
5,000 HB sold as Soviet, but I think it is Hungarian copper wash on PKM belts
8,000 Silver tip Czech steel cased
9,000 or so Albanian brass cased
Various odd case lots over the years plus some that I need to dig out from the bottom of the piles.
