I am new to this forum but old to reloading. I bought the Browning Hells Canyon in 6.8 Western. As stated, no published data for the 175 TGK. With an educated guess, I started low and worked up to an average of 2,789 fps. Using 56 gr of IMR 4350. Factory Browning ammo in 175 only clocked at 2,710 fps. I measured my chamber at 2.977".magazine limits COAL to 2.965. Shooting cloverleafs. Hope it helps everyone out there
