Back to bullets… I’d never read this guy’s stuff, but he’s clearly seen a lot of game shot, his stuff’s not theoretical. He neatly illustrates why not to go to the heavy for caliber end of the bullet weight thinking it means harder hits.
I have found the work outlined in Terminal Ballistics Research really helpful.. I have hunted coastal grizzly once, back when LEH hunting was still a thing. I took an 8'2" boar with a 338WinMag , Swift A Frame bullet. Bear was not charging and 1 shot did the trick at just over 100yds. I usually load 250gr Barnes original loads in my Win 71 if I am hunting deer/elk/moose in thick timber where grizzly are known to be around.
Later in the article you quoted the author observed:
"The use of core bonded bullets in the 348 deserves careful consideration as these tend to work best at impact velocities above 2400fps. Having said this,the flat point bullet designs used in 348 help(regain) terminal performance at lower impact velocities. The net result is that providing ranges are kept short and animals are of a relatively large or stout build,it is possible to obtain a mixture of good trauma (fast bleeding) and relatively deep penetration with core bonded bullets."
That sounds like large bear medicine to me. Breaking large bones in these situations always has seemed to be a good idea to me.I think big bullets break shoulders better than smaller bulletrs no matter how fast they are going. I have acquired some Swift A Frame, Woodleigh and NorthFork 348 bullets to try along these lines. I still feel more comfortable with my 348Win over a high velocity smaller caliber round.
I favor the lever action over my second choice ,a Remington 350 Magnum bolt action carbine, because of relative rapidity of fire I can get with the lever action. I can't work any of my bolt action that quickly. I sure some other folks can, but not me.
Cheers!
