Ok, Now that I got another laugh at those pics of my G-Kids work, I have a small rant and I may need some straightening out, here goes..
6.8 SPC & 6.5 Grendel on Elk and Moose.
Now then, my side of the fence comes as a PH for well more than 25years and I've been a Ballistics Engineer for well most of that, wherein Terminal Ballistics is my Game. I'd didn't want to chase wounded critters over the next range, trying to recover them. Meaning the 270 Winchester can kill, but the reason it's all but a dead cartridge is because if you do shoot a Muley or bigger, and it runs for 3 minutes before succumbing to the effects of the bullet (an all too recurring problem with the 270 win), it may take two days before you see that animal again. And by that time it may have rotted (prolly).
Now then, if the 270 win (made by necking down an -06 to ,270) is all but dead, because it won't readily kill anything, why is the 6.8 SPC better? the 6.8SPC is a 270 Win-very Short.
As for the 6.5 Grendel on the bigger critters. Take the bigger case (6.5x55 Swedish Mauser, which is a kinda-sorta, re-necked 308win) and hands-down, very much more capable than the 6.5 Grendal. I own a 6.5 Swede and have a great story that Illustrates the problem I'm trying to talk about.
So, My Dad and Baby Brother are on a moose hunt. They have a Moose hemmed up, at 300 yds, using a well known moose killer bullet, in the 6.5x55, in a marsh. My brother is shooting the Moose, for 11 hits on the shoulder, where-in they can see chunks of hide blowing off the shoulder, and on final inspection, all shots were in the Kill-Zone. The moose, when hit, would take a step and then resume eating. It wasn't until my Dad, with one shot from his Garand, using 220gr-RN bullets, ended the situation.
Now, don't get me wrong, the 22lr can and does kill everything on the planet. I myself, in my more crazy younger years as a kid, have killed a fully grown moose with the 22lr and dozens of whitetails. But, I'm NOT recommending the 22lr for moose or anything else. Just that under the right conditions the puny 22lr can get the job done.
But, If I'm not recommending the 22lr for big dangerous game. What makes the 6.8SPC and or the 6.5 Grendel any better to recommend, under the circumstances I just outlined??
What am I not seeing? And don't answer with.."They are better than your finger".. That's a given and the fact that they are tack-drivers, kinda-sorta, is also a given. Ballistically Speaking what am I missing?? Right now I think the 6.8SPC and 6.5 Grendel are Irresponsible for Elk/Moose, even though some, on the other Channels declare 300yd kills. What say you?
Again, in a full-blown survival situation, use your 22, or 6.5 or 6.8. But if you've got to worry about animal recovery, over the next range or that the critter might just stomp a Mud-Hole in you..you might want to use something else??
