[QUOTE="Fiftydriver, post: 252002, member: 10"] Just to get back on topic. I believe the question was what is the fastest 338 out there. Well, to compare all the different chamberings, we need to use a standard which would be the same bullet in all with the same length barrels so lets do that. Lets say 30" barrel length in all, even the 408 CT based wildcats. This does put the really large 338s at a disadvantage but all things will be equal. These are velocity tests from rifles I have built in each chambering, all using #8 contour Lilja 1-10 twist, SS fluted barrels. Velocity is an average of 5 shot string in 50-60 degree temps 338 RUM............................2745 fps 338 Edge...........................2865 fps 338 Lapua.........................2870 fps 338 Ultra Maxx...................2945 fps 338 Kahn............................3004 fps 338 Allen Xpress................3010 fps 338 Allen Magnum..............3315 fps ** ** Just wanted to make the point to make this clear that these velocities are from a 30" barrel, not my standard 33-35" lengths. Just so we do not get confused that 3315 fps is the max velocity in a 338 AM. Would also like to add that these are examples of one rifle per caliber using Lilja barrels and they tend to run a bit lower in velocity because the bore diameters tend to be a bit tighter then average. But with same bullets and same barrel lengths, you at least have some idea the difference in velocity. Maybe some day I will be able to do this list with the new Wildcat bullets but not yet. No hints yet on the new owners as its not solidly set in stone that the sell will go through so out of respect for the potential owners and Richard, I will not say anything until its a done deal. I will however say it would be a US based company if the current interested group gets it and in my opinion, they would do a very good job making bullets. Hopefully for both parties and all of us, it goes through soon. [/QUOTE]
