Re: 6.5 Sin

Now hold on here.... I thought the SIN was based off the 375 Ruger case???

    Sorry, I meant the 300 would be easier to do the 6.5 so you don't have to go all the way down from 338. The Dakota is a little larger at the base and not smaller than the RUM.

    It is based off the shortenned RUM and not the Ruger.

    Dakota brass is .003" smaller at the web. Fact not fiction. That's a significant amount if you are going to use it in a chamber that was intended and designed for RUM based wildcats. --- RHB

    7mm, my point is the dakota has a .545" case rim diameter and the RUM a .539 case rim diameter so to use the Dakota brass the bolt face probably will need to be opened up a little. I recomend using the RUM brass when Devin gets dies for it. Because the RUM is slightly larger just in front of the case rim a slight bulge will develop there when using Dakota brass. That plus the short neck is why I do not recomend the dakota brass as a permanent solution. That was and still is my only option for now. I wanted to get all the data I could as quick as I could. The performance is the same with either brass for collecting data. I hope Devin gets some dies out soon to remedy this.

    Re: 6.5 Sin

    I haven't posted on here for a while but I have done some testing. so far I am getting 36-3700 fps with 140gr bullet and 3550fps with the 160gr Matrix bullet. I will get doing a lot more testing with the 160gr before I go back to the lighter stuff. my original test barrel is a 30", I am also testing a 24" too.
