I have a wildcat 6mm-257 weatherby mag. It is built on a trued sleeved rem 700 action and fitted with a Maddco,Australian barrel)30 inch 1:8 twist. The rig is intended for 1000 yd B/R
Cases are weatherby 257 mag necked down to 6mm.
At this point I am loading 105 bergers with 67 grains of an australian powder,AR2214)it is a little slower than RE 22 and very close to hodgden H1000 but so far cant get a bullet to the 100yd target. They disintergrate at about 75 - 90 yds any ideas ???
