[QUOTE="hammertyme, post: 250896, member: 12863"] To my knowledge Kirby Allens 338 is the fastest. As stated it needs to be on a larger after market action. However I have two 338 X 378 Keith Thompson Improved. One is in a undesignated Savage Target action on a handgun platform and the other is in a Savage long Action. Just working on loads using the 245gr .9 BC Lehigh bullet and out of my handgun (17" barrel) I am getting well past 2900fps. I have done nothing yet in the rifle as I hunt with a handgun only. I do know a couple guys that are running this cartridge in rifles and are getting 150fps more velocity than the 338 Lapua Improved. Increase the barrel length from 26" to 32" and the velocity gain will probably increase another 150fps? Neal [/QUOTE]
