You're killing me Brad, ha! Those are some super fine bulls! I had a chance to try R17/168 TTSX in the WSM. It worked out great as I wanted to see if R17 "behaved" over 80 deg. In two rifles of mine, R26 "did not, went wonky" over 80! Our weather turned off hot ( for us) 83 deg the PM I shot the trial loads. 64gr/R17/Win prepped new brass/Fed 215M gave easy extraction and 3 shots ( I always start out with 3, go up to 5-6 later if a load shows promise.) anyhow, 64gr went into .40" and 65gr/went into a nice, rounded .75". 66gr jumped to 1.5". I will chrono both 64/65 and just see how fast they are going. I am fine if the 64gr is between 3000-3100fps. I would almost bet, right now, since this rifle has a tight chamber, I have plenty of speed! I was really impressed with R17 as I have used it in several cartridges in cold temps where it also proved very good. R26 does for me too, in the cold. But, I am settling on the 168 TTSX. I will try out the 150 TTSX later in a 30-06. Thanks for the input guys! And Brad...you are one bull elk killing devil! ha
