The bautte my good friend was running seemed to like most 150gr choices. We were launching SST’s and the 150gr BTSP very well, right at about 2700fPS. Mostly Varget around here, 42.1-43.2 grains for those.
Those were loads that I had spun up for my Sako black bear, they were .4,.6 in that rifle and They hung in around .8-.9 for the Bautte rifle.
It shot the 150gr Nosler Ballistic tip well too. It was sitting at 1.1” @ 2650fps for good results.
Trying the 150FMJBT Hornady it was at 1.5” or so on both rifles. Roughly 2700fps there too.
Being the tikka was so close to the Sako, I’d venture to say the 150gr Federal blue box or non typical would have shot well in that tikka , as it is .5-.8 in my Sako.
