Districorp has been out of 6.5X55 Swede for a while
The Igman 6.5x55 I got from Districorp was so-so. I bought 500 rounds of it, and have been using it up quite slowly since it has some problems. I still have about 100 left.
The flash hole in the brass is very small, making the powder ignition quite poor. It is worse in cold conditions, so if it is less than 10C I do not even take it out.
What happens is that the charge seems under-loaded, likely due to the minuscule flash hole, and the resulting ignition does not seal the chamber properly. There are powder marks and residue all the way back to the case head, even inside the rim. And the bolt face gets smeared in crap.
As well, the powder is very sooty, not so much a problem until one of the above scenarios happens, then you are cleaning the bolt for a long while afterwards.
As for reloading this brass, my mileage also has not been so great. You have to drill out the flash hole to make it standard size, de-crimp the primer pockets, and anneal it like crazy almost to the point of cooking the brass because it is so hard it has a "springback" memory condition that I find causes the bullets to be too loose without intensive annealing.
I find it is as cheap to reload as it is to get the Igman. And my reloads are superior.
Maybe I hit a bad lot, but the above I describe was seen by others on a US forum, and the small flash hole is widely known in 6.5x55 and other calibers too.
