[QUOTE="Guest, post: 572"] Mr Jones, In all of the Mod 70 300 Win Mag's we buy, we always remove the magazine box spacer, trim the bolt stop back and then install a 300 Weatherby follower and spring. This, coupled with Winchester's long throats found in their Mod 70's, allows us to increase the 300 Win's COL to 3.540" with both the Nosler 180 and 200 grain partitions. This gains back some of the volume lost in the 300 Win with the standard COL of 3.340". Stated "book" velocities and better, are easier to achieve in 24" barrels without excessive pressure signs by doing this. If you reload you can have the gunsmith throat your Mod 700 barrel to any COL length 300 Win (or the 30-338) that will fit into the magazine box. This will eliminate the deep seating problem associated with the 300 Win. I don't have any real world experience with a 30-338 but I think both calibers are essentially equal from a ballistic standpoint. That is what seems to be the trend in reloading manuals. So the fact that you could get factory ammo in a pinch for the 300 Win, may be the only advantage of one over the other in a Mod 700 action. Both are excellent calibers for elk. [/QUOTE]
