[QUOTE="backwoods83, post: 537645, member: 29890"] My vote goes to the 300 roy, ( 300 wby mag ) have someone do a match chamber with only .060-.080" free bore. Yes it only hold 5grns more than the win mag, but typically has about 6 grns more usable powder space and a much better shoulder design than all the others mentioned. In the manuals it only shows a slight advantage over the win mag but they typically use test fire arms with no free bore and only 24" long. I know for a fact that a 300 wby will push a 208 amax over 3200fps with H1000 or retumbo in a 28" barrel, and I also disagree as for the wsm keeping up with the win mag because the wsm is designed to shoot much hotter powders than the win mag to get good velocity in shorter barrels, when you go with a long barrel and powders such as H1000 and Imr 7828 the win mag will hold 100fps+ advantage over the wsm.
