First a thanks to mstreddy and Bugster for the 8mm Berdan primer brass!
I now have an assortment of brass (deprimed) from the '40s to the '70s. I will be loading some 190 gr. gas checked lead with IMR 4198 and some 170 gr. jacketed RN using IMR 4350.
Visually inspecting the brass, some of the flash holes look considerably smaller. I think the NNY brass has flash holes measuring about .038" (just under 1mm). Using a paperclip that measures .031", I can't fit it in several of the holes.
I don't think it should be a problem with the faster burning 4198. But can anyone see it being a problem with the slower burning 4350?
The berdan primers are from Tula KV7.62N.
Thanks!
