308 - Big Game Effective Range

matching sd, construction, and impact velocities for game intended is a bit of voodoo magic it seems but 308 150's in rapid construction is about as good as you can get for all but the biggest game here, and in the typical 0-400, that blue box 150 psp is the lightning formula at those velocities, most of its work will be done over ~18" and nothing wasted, we didn't move up to the 165/180's by accident for larger game, the sd gain and velocity loss doubles down on increasing penetration as you retain more sd as you slow things down so you'll get those elk/moose penetration depths 20"+ as you move up, but likely won't notice near the lightning drt's as you do with the soft 150's on black bears/deer, still the 308 has velocity ranges that favour rapid construction bullets when going 165/180 but keep with lighter bullet construction formula to increase internal work, putting tough bullets in 308 will certainly up the penetrations but don't generally leave as much work through the good stuff, better tougher stuff moving faster like 30-06 and up

the same combo killed a moose but the operator is not on cgn and she s using what work for her ....

Whoa; might need to put up a heresy alarm. Are you seriously suggesting that one should use the light bullets on the light game and the heavy bullets on the heavy game? Thinking like that might even lead to belief in using the soft on the soft ones and the hard ones on the hard ones, I don’t know if thats heresy, madness or just not breaking any new ground. Probably never know, some mysteries will never be solved ;)

oh hey, don't have to tell me, I use the nearly same formula on 3/4 scale and have a moose too lol, she's got plenty for it, I only burn 30 grains of powder but otherwise identical formula on bullet and even less fps, I start at 2400 fps, by 420 yards I'm down to 1800 and blows through quartering deer no sweat with 6.5 123 gr eld-m's at 420, the 150 308 has I think .223 sd same construction and since I'm a few grains lighter and a bit slower I compensate with the higher .252 sd (same as a .308 168 gr .253) but overall nearly same formula and that's what makes it work so well, not the head stamp or the extra 11 grains of powder...the formula for game intended, 15 head big game, 5 seasons, me and the kids, 163 yard average shot distance, 13 yard average recovery distance, 10-420 yards...place em easy, fill them tags and break out the knife, walk right up to everything after shooting, she will never need anything else, neither will we, when you drive it and know its capabilities that's it...people can say it's not enough all they like, freezer and walls will argue back better ;)

well that's an even more subjective way of saying it lol, I try to objectify the formula as much as we can for people to explain what we learned by trial and error over the years lol, we can use at least a few more numbers in things to help get the perspectives more thoroughly understood, it's not hard to screw the formula up if you don't understand it, we will solve these mysteries, just a matter of time, it's one bite at a time with this elephant though, sure wish you could run that .257 bee cull back with the 6.5 cm and 140's one day, and also once we eat that elephant it will help explain more objectively why you observed such awesome performance from the certain 7 rem mag combo's you've seen on the northern bigger critters for the great drt ratios...never was about the head stamp or grains of powder burned which are just byproducts of getting the formula right for game intended ;)

did ya see that other thread with the article Ardent commented about around the 8.5x55 and how they were trying to get the sd down for shorter recoveries? bet that sort of comment hasn't made print very often, very interesting indeed...there's a formula in there somewhere, it's not what many think, most just get it right by accident due to what's on sale at the store and the typical 20th subjective recommendations on headstamps and calibers

You shoot factory ammunition in one cartridge. Try expanding your horizons a little. The formula speculation takes care of itself.
 
Most 308 winchester hunters are still dressed in blaze orange, with a pile of antlers hung in the rafters, have never concerned themselves with how far it is effective.

only the last 5 years, and if the kids were going to use it, so was I, before kids I shot a lot of other stuff, even things you would approve of, the .270 win with wsm with 140 ab's took lots for me, iron sights 30-06 what I started big game life with, but I am starting to get bored, just gonna throw and elk and antelope to get my species count up to 8 with it (bulk of Alberta's offerings), then I might play with a new Hawkeye hunter as I've got a boney for that rifle so it means I'm going to add a cartridge to the safe at some point...will see which way I go, should have the elk/antelope thing wrapped this season...6 seasons with one set up is a long time for me to be playing with the same thing, but works great and enjoyed the ribbing from those who think it's a squirrel cartridge, our grendels aren't going anywhere, they will be with us always and we can always lean back on them anytime, kids will run theirs until they get out and start buying whatever they want so quite awhile yet, and I'll never give mine up, too many good things happened for this dad, such a fun and effective set up

if 308 is mucho effective and you copy that formula with just a little less powder...stands to reason still effective, and it is, that's all the grendel is, 3/4 scale 308, my rafters, walls, freezer etc. look great but I only run a blaze orange toque when on public land ;)

back to the .308, with the 21st modern bullets you squeeze more distance out of it, fight wind better, so for those who want to smack 350-500 lb red stags at 530 yards with factory ammo 178 eld-x out of 22" barrel and watch them fall down on the spot...giver, .268 sd at 1820 fps with right construction is a strong formula for things even bigger than red stags, 550 yard elk/moose combo there and off the shelf rifle/ammo to boot, the 21st century is so much more fun when it comes to the gun stuff, not sure I'd be content to throw the 150 PowerPoints, when I look at 308 I start at 165 grains, can't help it, my min sd formula is ~.25, and, i need to be in the .5 bc range or my brain won't be happy either...anything less is too 20th century ;)
 
lol Dogleg, stick and string is pretty deadly, most of the antlers on my wall come from zero powder haha, all these powder burners are like cheating, even the wee grendel
 
Yep fer sure. Just checkout Jim Shockey's hunt records with muzzle loaders.

A well built modern muzzleloader is an extremely accurate and powerful firearm. Accuracy wise they will give most centerfire hunting guns a run for the money and with new bullets and powder can be reloaded rather quickly by someone skilled. Ive taken lots of game with mine and nothing has died any slower than those shot with a centerfire. Good shot placement with good bullets will anchor almost anything on this continent. One hole groups at 100 yards are actually easy.
