I have 3 also. A 1-B 280, a 1-B 270 WBY and a 1-V Stainless 204. The 204 has a Kepplinger single set, but the other 2 are basically untouched.
The 280 is my everyday Deer rifle, I can't remember the last time it's missed, probably at least 12 or 15 Deer back. Killed a 10 pointer with it last month at a lasered 310 yds with a handloaded 120 TSX. The 270 WBY I just basically look at, LOL. The 204 has taken groundhogs out to 400 with factory Hornady ammo. It shoots factory stuff so good that, even though I have the dies and a good stockpile of components, I haven't bothered handloading for it yet. Not much room for improvement.
I love all 3 rifles.
Surprisingly enough the triggers on both 1-Bs are pretty good. Plenty good for Deer hunting. I've never messed with either. I have a trigger scale and the 280 measures at 3 1/4 lbs, a nice crisp 3 1/4 lbs. Good enough in my book.
