[QUOTE="NesikaChad, post: 218107, member: 7449"] [b]6X47 Swiss Match[/b] I built my first rifle on this cartridge in 2002. It was an NRA course gun for a customer in CA. Back then, I couldn't get brass for it so a friend was actually picking them up off the rifle ranges after the Swiss National Rifle team finished practicing, and then mailing them to me. These were original RUAG pieces. I also started forming my own from 260 Rem brass much later. Velocity. RUAG advertises a velocity of right around 2850fps when loaded with a 105 grain Hornady A Max bullet. I could never get that velocity. Try as I did, I never was able to duplicate it without seeing signs of pressure. I used Varget (old lots), 4831Sc, Win 748, N-140, and good old IMR 4895. As soon as I got much over 2750 I'd start seeing ejector marks and flat primers. Guns always shot well, (I've made four guns in this caliber) regardless of how the bullet lumbered along. I think if you squish this down to 6mm and stoke it up with a light bullet, you'll really have something. Sounds like a neat idea to me. I'll stick my neck out and guess that with a bullet in the 60 grain range you'll be in the mid to upper 3000's for velocity. I think the combination of the lighter bullet weight and smaller caliber will keep the powder selection right in the same ballpark as if it were a standard 6.5X47 shooting 140's. Lets see how full of ca ca I am. I guess either a 7.5 rem SR primer or CCI BR with the case filled to the neck with 4831SC or N-140 and the bullet just off the lands will make this a screamer. Approach this load gradually is my obvious safety net here. Don't want anyone blowing themselves up. Good luck. [/QUOTE]
