I've had a 300 wby on a sako and a 300 rum on a sendero. Both were fast and accurate but that sendero had a super nasty fast kick with 200 nabs at almost 3200fps. I don't have either now anymore. If you can't do it with a 150gr mono out of a 30/06 at ~3000fps you need a bigger bullet imo. Not a faster one. I have now skipped the 30 cals all together (other than the 30-30) and use a 7mm rm for smaller stuff and a 338 wm for bigger stuff. The 338 wm btw weighs ~7.5lbs ready to hunt and is much nicer to shoot than either of my fast 30's.
