[QUOTE="yawn, post: 419846, member: 13540"] I have around 700 rounds through my cooper 280ai using nosler brass.New brass has been trouble free(I heard it was made by Norma?) 2 issues Iv had, firstly the nosler brass gives me internal donuts after the second or third firing.Using the 162 amax and the 168vld the throat lenght means I have to remove the donut as the bullet is seated deep enough to be a problem,not to much of a hardship realy.Second, the chamber in the cooper is tight and the redding match die was a touch on the large side( actually it was the same size as the chamber so after the 4th firing extracion became dificult.I got a small base body die which helped but not quite enough so Iv had a thou taken out of the rear of chamber now all is well. at present using norma .280 brass and so far after 4 fireings I have no donut, Also have some lapua 30-06 to try. And you will love the cooper:) [/QUOTE]
