    New GAP Extreme Hunter in 6.5 SAUM

    There are tests out there on the internet with the temp stability of ramshot. They tested from -40 to +140 and saw a 2 or 3% swing in velocities over those temp ranges. Assuming 3080 and 3% that's 92 fps over a 180 degree temp swing. 2% is 62. Scale it down to practical conditions and it is...

    New GAP Extreme Hunter in 6.5 SAUM

    That load is 62 grains of magnum. Velocity is 3030 w 140 JLK. Pressures according to quick load is around 55k. This group is 64.7 grains of magnum at 3180 fps. I believe pressure was around 61k. Yes both are 3 round groups. The 3180 load shoots under half moa at 1050.

    New GAP Extreme Hunter in 6.5 SAUM

    I've shot Ramshot magnum in both the bbls I have chambered in the SAUM. One with an 8 twist with a .109" freebore and one with an 8.5 twist and your reamer design with the .081" freebore. Both have shot extremely well. The 8 twist I was getting 3180 with 64.7 grains of powder and a 140 JLk in a...

    No mine were not built by GAP. Cloud peak Gunworks did the smith work on mine. One is built off GAP's reamer design

    New GAP Extreme Hunter in 6.5 SAUM

    I know you were addressing George but I found the same thing on QL. I have used Ramshot magnum almost exclusively with both of mine. Ramshot line of powders are also surprisingly temp stable.

    New GAP Extreme Hunter in 6.5 SAUM

    I shot them out of my 8 twist bbl and they shot well at 3000 fps. I have an 8.5 twist bbl as well and shot one group so far. First two were touching and the third landed about 3/4" low. I am guessing that it was me. I am trying to get out to shoot again if the wind would quit blowing. We've had...
