Best there is - Lapua .300 Winchester Magnum Unprimed Rifle Brass

In my opinion the Lapua brass in 300 Win Mag is the best there is. The brass is consistent, uniform and lasts many reloads. Yes, it is expensive but worth the extra $$. Primer pockets are clean and round and the flash hole is chamfered. No need to first clean up the brass. It lives up to its reputation.
