Take a .30-06 or .300 magnum as a for instance. The energy taken out might be no more than that of a .22 rimfire which is a tiny tiny bit of what it had when it hit. There are too many advantages and no disadvantages to an exit. Now that's NOT to say the bullet should not do damage on the path out as it definitely should. We're not taling FMJ here were're talking expanding softs.
Energy smenery as I always say. It is meaningless and just paper energy anyway not real world energy. If you'll forget it and just not mention it every again you'll be far far better off in understanding how bullets kill game.
Supposedly, there have been instances of people not seeing one deer behind another and killing both with one shot. My brother
has a friend in SW Colorado who claims to have done so with a .300 win mag. I now question the validity of such stories after
reading an article in Nov 09 issue of "Precision Shooting" magazine. Stephen Boxford was given an extensive tour of the Barnes
Bullets plant and got to be there during testing of a few of their bullets. One test was to check the speed of a bullet AFTER going
through a block of ballistic gel, which to appears to be 12" long. Results with a 180gr .308 TTSX were:
From a .30-06 impact speed of 2,526, exit speed 273fps.
From a .300 RUM impact speed of 3,003, exit speed 255fps.
No, the exit speeds are not mistakenly turned around.
Therefore, Bill, I digress. Even these bullets which retained all of their weight have exerted close to 90% of their speed, thereby
expending most of their energy, and you were correct in comparing an exiting premium bullet to having similar to a .22 LR.
Steve P - You totally, completely miss my point. Only a complete idiot would shoulder shoot a deer with two of the three bullets
you mentioned. I would not use the Nosler BT on a deer, even for a lung shot. Gimme the 85 grainer in .257 for use in my .25-06
and I would use THAT one for a lung shot (which may or may not exit), but there again, only an idiot would use it for a shoulder
shot. Wasted meat ya say? Probably would not get a chance to find out as it would more than likely result in a chase into the next
county or two. The 55 grainer especially would do little more than a sub-surface wound in the event of a shoulder shot. By the
way, WHERE is it legal to use FMJ's on deer??
Another "by the way": I now hunt (because of legality in Iowa) exclusively with ML's (can't stand the thought of using slugs).
I have used both frangible and all coppers, depending where I'm going to hunt. An XTP or even the SST in .451 is frangible
at a speed of 2600fps (Savage 10MLII), whereas Barnes Extremes are not. I can be at both ends of these bullet debates.
In spite of what one's beliefs are about bullet choices, there is one thing which is not debatable, especially for meat consumption.
No matter what bullet is used, nothing beats a well-placed, humane shot. And for that to happen, it takes a lot more practice
than far too many people actually do prior to the hunt.
