Lucky I'm only 30 miles south of the 49th. Retail powder is $30+ so it's rare I buy it. I usually buy in bulk from Powder Valley and split it with friends.
I have no need or desire for the big boomers. The most hot rod cartridge I shoot is a 300 Win Mag, and its in a 15lb target rifle with a nice suppressor on it so it doesn't kick or make much noise.
I have several ARs and several different optic arrangements on them. My favorite setup is very similar to Guy Miner. I have a Leupold VXR 3-9 in the Leupold mount.
Short of dangerous game in Africa, I wouldn't hesitate to use a Nosler Partition on any animal.
Bullet expansion is energy transfer, energy transfer is hydro-static shock, that is what kills animals.
I got my Timney for the Predator and it is a really easy install and excellent results. I ordered it with a 2lb pull and that is what they sent me. I never cared much for the blade triggers anyway.
