Nice shooting. You get to play with all the really neat toys.
Was the load you used subsonic? If not, any thoughts on how much quieter the suppressor was? How much more elevation?
Had a chance to do some LR shooting with my 300WBY and got it out to 1800m (Wild rangefinder). Using a 155gr molied Amax, I was impressed. Just got my 300RUM with 35" barrel back from the smith. Have to build a stock, then will get to launch some 240MK way out yonder.
Take care...
