Whlst in USA I purchased a a box of new Hornady .204 brass. Now its advertised/marketed as being high quality brass that exceeds SAMMI specifications and alike so I expected it to be pretty damn good.
Anyway on Sat evening I was on .204 ruger .com and looking at loads. It seems the concencus is to use Remmington 7.5 primers, fortunately I have a large stock so I thought I might as well prime my cases.
Now I thought I should give them a quick check over not expecting them to require any prep at all. Well what a shock, close scrutiny of the new cases showed that the flash holes in some were not round but elipical and some even appeared to not be straight, but angeled. I thought I was going mad so got out some brand new .223 Lapua match cases. They were nigh on perfect. Central flash hole not requiring de burring and perfectly straight. Anyway I ended up deburring all 50 of my .204 cases and was very surprised that they took quite a bit of preping. I still think some of the flash holes are not parallel to the case walls.
Has anybody else found this to be an issue?
Its difficult to photograph/describe and unless you have a new Lapua case you cannot compare the two.
