I got my Bullberry 7.62x39 barrel Friday. It has a .308 bore which allows for a lot of flexibility in bullet choice. So far it's a fantastic shooter with the loads that I have available. I think that this little cartridge is a great cartridge for handloading in a good firearm, and is very overlooked as a serious cartridge because you mostly see it in AK-47's and SKS's. In those firearms, it's performance is much less than stellar.
However, most of the reloading tables that I have for this cartridge are for .310 bullets, which is very limited. Bullberry does not recommend using the .310-.311 diameter bullets in their barrel, and especially recommends staying away from the cheap imported ammo.
Does anyone know of any good reloading tables for this cartridge that use exclusively .308 diameter bullets? I've managed to round up a few loads, and they all work great, but I would like to know if there has been any testing done with this cartridge, especially with cast lead bullets. I would like to have some load data on heavy lead bullets like 150 grain and up.
Any information would be appreciated.
