[QUOTE="Darryl Cassel, post: 22745, member: 34"] Texas Questions. 3900 FPS with a 250 gr 30 cal bullet???? A 20mm cannon neck down? 110 grs of what? If it's powder you were talking about, that amount will not give the velocity you mentioned. Brand of 250 gr bullet? What BC? I would think it would be a 240 gr MK. unless it is a special custom bullet of Warrens. Then again 110 grs of powder will not give that velocity unless it's rocket fuel with boosters added. Case used to achieve that velocity? It would have to be in the 150 to 175 gr powder volume size, at least and probably MUCH more. Something like that would be a lot more overbore then the 30/378 is. More info needed on it like, who made the claim and who did the testing. The 408 is legal for competitions. Rules state that it must be no larger then a 40 cal. ---A .408 diameter IS a 40 cal. It ceases to be 40 cal when a bullet reaches 41 caliber or .410 diameter. Just like the 308 is a 30 caliber. I think at 3200 FPS with the Tomahawk and 240 gr bullets that's about right for the 30 Cal bore and factory mag actions. You could neck the 505 Gibbs case down to 30 cal and give more powder volume. I would rather neck that case down to 338 and shoot the 300 gr MK in it. Then again, you will need big custom actions to use it. For the regular hunter and shooter who wants a big 30 cal that will certainly do everything needed in a 30 cal. on a factory action, the Tomahawk fills that nitch.
