No question, it's a little bitty booger...but efficient and inherently accurate...but you know that already. The only complaints I've heard on the Norma brass is the rims seem to be thicker on some and the shell holders aren't quite working. I hadn't heard about the large primers
However, you don't have to use the special reamer but it will cause you to have to shave off a fair amount of the neck if you don't. To me that would be an advantage enough to swap reamers...if my accuracy didn't go away long before I need more neck, but you don't need quite the accuracy I do.
I'm like you, I like my Lapua brass and fortunately...I've burned at least one brx and dasher barrel so I have one to fireform either with now.
Thanks for the link, I'd been waiting on the TL-3 because I believe my next build will be a short barreled brx or dasher just to see what it will do in that game with a suppressor.
