I have a box of sierra 175gr .277 tipped game king. The only published data I can find for 6.8 western is on hodgdon load data.
, but it only has data for 170gr bullet.
So how can I safely use that 170gr data to reload 175gr?

the 175 TGK has a lot longer bearing surface than the berger. start 1-1.5 gr under min and do a quick pressure test. just one shot at each powder charge and check velocity

I started low with 48 gr IMR 4350. Went up slowly until I reached 2,760 fps. Factory browning ammo in TGK clocked in at 2,710 fps with a COAL of 2.90”
I measured my chamber and it is 2.977”. Due to magazine length you can only go to 2.965” with 56gr of IMR 4350 will average 2,789 fps and shooting clovers at 100yds. I hope this helps all you out there needing info for 175 gr bullets.
