I don't know about the WSM but can relate a tale about the 340 B and 2 boxes of carefully crafted hand loads with 210-gr TSXs--I left them at home. I had no ammo with the exception of three rounds that were in a leather cartridge carrier.
Not until I got to camp in northern CO did I discover it. The nearest "big" town was 45 min away, it was nighttime and I had serious concerns as to finding any as the only sporting goods store I noticed on the way in was a "Bobs".
They had
[/i] one [i] box of 340s with 210-gr NP which I bought but knew would fly differently than mine but hoped I could get by with the three. I killed a killed a bull across a small canyon at about 475 yds with a single shot.
I even make lists but did some content and bag switching at the last minute and that's how it happened; stuff does happen--to me at least. I usually leave stuff at the hunt site rather than at home though
.
