[QUOTE="Dirtrax, post: 2495712, member: 78945"] As I recall, Nathan had extensive knowledge of a “straight” 7-300 being on the shelf due to a lengthy conversation with Broz on this site. Nathan chose the 30* shoulder for whatever reason and spec’ed it in 2-3 generations if reamers. Were it me I’d have gone 35-40* but he wanted the necks to grow. Reamer specs are .299” to allow this. If you have had conversations with him personally I won’t dispute your claims. The Practical is a fine cartridge and I own a rifle chambered in it. Forming is easy. Dedicated dies are needed. I did in fact have the throat cut .050” forward to accommodate bullet seating as well as having Shawn and Bob at DE give it the +P treatment. The throat has moved about .0015”/hundred rounds of slow, controlled fire (for the most part). IMO the 7-300 in any of its forms is a winner. It gives up little to the bigger 7’s with less wear and tear on equipment. Next time around I’m considering a 7-300 PRC to take advantage of the more modern brass/case profile. I may even AI the darn thing as I single feed regularly, but that’s another story. [/QUOTE]
