The reasons you describe are the reasons Federal brass goes straight to the scrap brass bin. When I was trying to use it...I would have to use a drill bit to break off the burrs....broke one tool already on Federal brass.Lapua, Norma and Nosler, you get what you pay for just like everything else in life. Ever notice how the flash holes are perfectly centered in those brands and usually no flash hole burrs either,
I assume some who use Federal brass don't clean the burrs off the flash hole. When I've tried to use Federal brass I end up with a huge pile of chips. That includes several calibers too!
Hornady has very clean flash holes...the only Lapua brass I own was 6.5X284. It was about the same as I have experienced with multiple calibers of Hornady.
I started with 100 pieces of 6.5x284 Lapua bras and have already lost 5 cases...I'm at 4 firing on those cases...which is about what I see with Hornady brass.
But I did use Hornady 25-06 brass to make my 6.5-06 brass. On the 8th firing lost about 20 cases on that firing, but none before that. I scrapped the whole lot on that firing
