I have been trying 140 ttsx with rl 17 after 100 loads fired I am starting over. I first went from 45 to 47gr in .25 jumps. good reports from 45.75 to 46.5 problem is I have been unable to repeat those results consistently. I have been shooting off sand bags from a bench and prone. Prone seems to have more consistent recoil and thus better reports. I keep thinking that it is just a very unforgiving rifle or a combo of that and pretty iffy load. I am going to run a set of tests next from 44 back up to 46.25. maybe the node is a little further down? If no success I plan to change bullets first then powder. Im thinking a 140 nosler, I might be crushing powder with the long ttsx. Who here has loaded this rifle and caliber? Interested in where in the load density started seeing improvement or lack of.
