I imagine that you are learning a lot about bullets - and bullet making - at your new job. Hope you enjoy the work and that you and your family are well. There are a lot of super choices, including Warren's products, and we have probably never had it so good. Last year year I ran out of time and went with factories, fact is they did a good job.
We just did a fairly big test (over two cases of ammo) of the .300 WSM
and had five shot groups at or under 1/2" at 100 yards with one of George Gardner's superb rifles. That was with Winchester's Supreme ammo in both 180 grain Failsafe and 150 grain Ballistic Silvertip. That is hard to beat, and certainly more than adequate for most hunting. I have never seen Failsafes shoot as well as in the .300 WSM.
