Another .358 caliber fan here. I've owned several whelens and Norma mags over the years, as well as a couple of 350 rem mags.

Sadly down to one now. Remington classic 350 Rem mag, had the barrel cut to 20" and sights reinstalled. Wears a Leupold Ultralight 2-7. And likes 225 SGK's over a stiff charge of RL15. Killed a handful of deer and 4 elk with it so far. Everything I shoot hits the ground right now, even lung shots. Closest kill was a 5 point bull at 30 feet in a brush hole.

The 350 gets taken out once in a while, but I grab my JES rebored 338-06 shooting 210 Partitions more often than not.
