bigcountry,
I have worked with .300 Win Mags and 180 grain bullets for about 13 years now. This past fall I found the best load I have ever tried in the guns I have loaded for. The load consists of:
New Winchester Brass
Federal 215M primer
76.0 grains of RL22
180 grain Nosler Accubond
Bullet is seated .015 from the lands
Average velocity for 5 shots in 70 degree weather - 3,184 fps.
Average velocity for 3 shots in 20 degree weather - 3,150 fps.
I am going to attempt to attach various targets from the day I worked up the load, and then a picture of my sight in verification target prior to my hunt this past fall.
Here is the sight in verification target. This was shot in rainy, breezy conditions and about 50 degrees.
