Holes smaller than .25" exhibit capillarity, so calibers smaller than .25" in military use *will* inevitably have obstructions. Ergo, the smallest caliber that should be considered is .25" [and independently verified by the Brits in an ammunition study they conducted back in the '70s, using altogether unrelated criteria!] Enjoying your articles very much, esp. the one lambasting the 6.8SPC, which was developed a few years after my proposal to base a new cartridge on the .30Rem case using a bobo of ~100gr in .25 or 6.5mm hit the Usenet rec.guns forum. How did they get it so wrong, when I'd given them everything except the final case length? ;-D ]Anonymoushttps://www.blogger.com/profile/07610851658311411621noreply@blogger.comtag:blogger.com,1999:blog-5557913977913148366.post-26674479670353757062015-10-31T21:52:08.189-07:002015-10-31T21:52:08.189-07:00Mr Fitch, thank you for this great piece of read!

Even if you have a powerful round, i.e .308 or 8mm Mauser, the round will over penetrate; None of the expansion will occur in the torso.

My studies on projectile trajectory show that with conventional technology the ideal muzzle velocity is 2,700-3,400 ft/s. Above that threshold, the exponential increase in drag begins to eliminate the gains from the greater starting energy, and weight begins to increase. Below that threshold, the ballistic coefficient needed to retain a trajectory comparable to the M4's becomes unrealistic.<br /><br />However, for a varmint round something like a 2.26" long necked down .224" 7.62x45 wildcat would probably be tits.<br /><br />You're absolutely right about the lack of evidence for the reputed poor effectiveness of 5.56mm. That's one of the frustrating things about taking this discussion into the public - often I find myself talking with others who accept essentially on faith the idea that larger calibers will be more effective. While the performance of M855 has certainly left a lot to be desired, virtually all of its replacements have exploited superior bullet design in conjunction with offering more energy and larger caliber bullets. The importance of the former has been proven by the very small gap now existent between high performance 5.56mm rounds like MK. 318 and calibers like 6.8mm SPC.Nathaniel Fitchhttps://www.blogger.com/profile/15011387972300996469noreply@blogger.comtag:blogger.com,1999:blog-5557913977913148366.post-88191818809249855742015-03-04T22:56:05.823-08:002015-03-04T22:56:05.823-08:00Hello Mr. Fitch,

Assuming ammo cost is the same between the two, would it be a superior choice in ballistics?<br /><br />On a side note: Your articles helped me realize that the 5.56 bashing articles were based on not a whole lot of evidence. I now consider the 5.56 a smart choice as a rifle caliber.Anonymoushttps://www.blogger.com/profile/06013611748898798360noreply@blogger.com
