I'm probably not with the crowd. I went 35 Whelen. For one thing I too shoot cast bullets a lot. I own several 35 caliber rifles. 358 Win, 350 Rem Mag's, and a Whelen.

The heaviest bucket I use is 250 grain Nosler Partition and 250 grain Hornady Interlock. The detractors will say the twist rate is too slow for heavier bullets. Yet others will say that a 338 Win Mag best bullets are 200 - 210 grain.

I suppose it will depend on if you're going to Africa, if you shoot cast bullets, if 250 grain premium bullets are too puny for your needs.

I prefer classic.
