A reprint on some swedish moose hunting data from 2007. I suspect a lot of you have previously seen this. It should be noted that most swedish factory 6.5 x55 140 grain ammo is only loaded to 2550/2600 fps - less than the 140 grain 6.5 creedmoor.

I am sorry that the posted data does not line up all nice and neat like it did when I posted it. What, if any, conclusions can be drawn from this information? I believe there are several things that stand out.
The first is how little difference there really is in the effectiveness of all the cartridges listed. Where is the big bore advantage so often toted for the 30 caliber we have been promised by so many as compared to the lesser bores? Surprisingly the lowly 308 did better than its big brother the 3006 did, and even the much speedier 7mm Remington Magnum had much longer travel distances than the 308 did. Many here and else where have argued against using the 270 on moose as being totally inadequate, and yet the 460 WBY shot moose traveled 70 meters as compared with the 270's 64 meters before they went down. The mild 6.5 x 55 (or 260 Remington for that matter) shot moose only traveled 41 meters on average. We don't see any real large caliber advantage until we get up to the 416 Taylor, which again is another low velocity round relatively speaking.
The second thing that stands out is the fact that moose traveled farther on average than when struck with high velocity rounds than they did when struck with the slower velocity rounds. The 458 Winchester magnum is the slowest velocity round on the above chart, and yet it recorded the second lowest number of rounds required to take moose and it clocked the shortest travel distances traveled, only 18 meters. The 460 WBY would be shooting the same bullet weights much faster, and the moose hit with those bullets traveled almost 4 times as far as the 458 Win hit moose did. Where is the high velocity advantage so often touted other than for flat trajectory and less flight time?
The higher recoiling rounds also contributed to longer travel distances traveled before the moose gave up the effort, probably because of poorer shot placement that comes as a result of more recoil.
The 338 Winchester Magnum and the 358 Norma Magnums were essentially a wash in spite of what the 35 fans maintain. The Norma required .3 less rounds to put down its moose, but the 338 shot moose traveled 5 less meters on average. The 300 Winchester Magnum required more rounds to put its moose down than any of the other cartridges listed, but they traveled less meters than the 308 and 3006 shot moose did. The 308 shot moose traveled 5 less meters than the 3006 shot moose traveled on average. So where is the 3006's advantage commonly touted by many American hunters?
The 9.3s present an interesting contrast as well, but for different reasons. The 9.3 x 62 has about a necked-up 3006 case capacity. The 9.3 x 64 is closer to 300 Winchester magnum class cartridges in case capacity. The 9.3 x 74 R is about the longest case there is around other than the 50 BMG. It is used in double rifles, drilling and combination guns. Hence the "R" indicating that it is a rimmed case. Out of necessity the 74 R case is loaded to lower chamber pressure levels because it is used in break action firearms, so its velocities are at least 100 fps behind those of the 9.3 x 62. The bullets made for 9.3 firearms are made to perform at the 9.3 x 74's velocity levels. That's why the 9.3 x 62 and x 64 shot moose traveled 4 and 8 meters respectively farther on average than the 9.3 x 74R shoot moose did. This is another case where less velocity actually helped on the bigger animals. Penetration actually is degraded because of over expansion at 9.3 x 64 case velocities. Apparently there really is something to the Hang Time Theory of lower velocity rounds being more effective killers on the bigger big animals...Rusty.
