Sierra 175 gr. TGK Load Data for 270

[980yds]

I just purchased an Xbolt 270 long range. It has a 7 1/2" twist and I would like to try the 175 TGK from Sierra. I called Sierra and they have not tested this bullet with 270, just the 6.8 western so they have no data. Does anyone have any recommendations?

Contact Berger's Tech Support for their 170 and use it as your baseline.

Here is what Berger sent me a while back when I asked about loading their 170 eol. I would work up loads from there. I would be interested to see how you like the sierra 175. I have been loading Nosler 165 ABLR in my Xbolt 270 LR

My .270 AI was built in 2012 primarily for the 165/175 Matrix VLDs. IIRC, I was using 58g H4831 SC, propelling the 175 at 2993 FPS out 30" Lilja 3G 1:8" barrel. I reached near 3100 FPS but group opened up and having pressure.
