I started developing loads and ended up with 2 bullets that worked well.  The 160gr Nosler Partition and the 162gr Hornady ELD-X. Time was short, so I ended up going this the ELD-X.  I was able to get the rifle with the suppressor to shoot sub ½” groups.  Basically a one hole group.  That was what I was looking for. So I went to Colorado and on the 3^rd day we spotted a bull elk in the oak brush.  He was about 350 yards from my previous ranging of the area.  Shot was from a prone position and was easy knowing I had great confidence in my rifle.  Being that I was using a suppressor, you could really hear the impact of the bullet.  The shot went through his left shoulder and both lungs.  He dropped and rolled 15 yards down the hill. Having a rifle that shoots with great accuracy gave me the confidence I was looking for.  It all starts with good products and someone that knows how to put together a rifle.  Tim did it with this one and can do it with yours.
