Remingtonman It is on par w/my 243 with less powder.
My 243 runs at the same speed but uses 12g more powder at least if not more depending on load.
It has much less recoil, is more accurate than my stock pencil 22" bbl 243.
My coyote load of a 55g in the 6x6.8 runs at 3675 w/32g h335, in the 243 the 55g runs at 3888 w/49g h380
Its so close IMO that the 6x6.8 has replaced the 243 which is now just a backup rig.
