Home Forums Hunting & Shooting Custom Rifles & Wildcats .358 Win project question

Here's a little more detail:

95% of my hunting will be from the hill country west here in Texas. Shots range from >100 yards to over 600. Most of this hunting is from box blinds or taking a seat on the ground. The primary goal of this rifle is a solid 300 yd (or better with practice) rifle that will hold it's umph out to those ranges.
Game will primarily be whitetail and axis with a possibility of an Addax.
Out of state hunting will SE NM for mule deer and Idaho/Wyoming for elk and mule deer. Thinking of either the 220 grain or the 225 grain Sierra's or Nosler partitions
