[QUOTE="AZShooter, post: 836536, member: 5219"] Based on today's shortage of brass the decision on which 7mm to make might be determined by availability. I solved that issue with the latest 7mm I built. I necked down 375 Ruger brass without relocating the shoulder as was done with the 7mm LRM. Haven't noticed any issues with the short neck. I decided neck it down with dies I had on hand. It took 8 steps and some neck turning but I got it done. PT&G sold me a reamer. The performance has been fantastic with two rifles I chambered myself. Both rifles showed a preference for 180s. The 162 or 168s had a slight velocity increase over the 7 rem mag. The 180s pulled away from 7 rem mag's velocities for a definite increase in performance. Sure it was a great deal of work, BUT I have an unlimited supply of brass! Every time I walk through Sportsmans I see 2-4 boxes. I have several hundred pieces now. Meantime the other bins have remained empty for months. I'd say buy the brass then go ahead and build the 7mm. It is stunning how rare some cases have become. Be sure to tell us what you ended up doing. Always enjoy reading what others are doing. [/QUOTE]
