In mu never ending quest to do something stupid I bought a reamer for the 6-300 WSM. I have 96 lbs. powder that shoule be an excellant choice for this round and just could not past up the reamer. So, does anyone have any data on this round? If not I`ll just wing it. I have 2 6-284`s but neather of them will shoot the 105 or 107 gr. bullets well and I prefer to shoot the heavy bullets for long range.
