Does anyone know of companies that work up loads for your specific rifle (BLR in this case) and sell them over the Internet? Does anyone offer anything like that? Ideally, it would be great if we got a few different loads so we could choose the one that suits us well. Does anyone offer something like that?
Check the gun shows in your area. Gun shows in my area usually have a couple of custom reloaders selling ammo. You could try their loads or see if they could load some up for you.
