Light vs heavy for caliber bullets on game

[Jaegerr]

I didn’t find anything online in a quick search, but I had a question on bullet weight.

I’ve been down the reloading rabbit hole before buying anything and personally wanting to load copper mono’s into a 300WSM and the consensus on monos is light and fast, but in bullets like partitions, bonded bullets, ELD-X, Bergers, etc is heavy for the higher BC which is a pretty straight forward desire.

How much does bullet weight affect terminal performance on game? It’s apples and oranges comparing monos to lead core bullets but for something like a 168TTSX running faster compared to like a 190LRX as an example. Thanks!

If you need terminal performance at range, then you are going to want to go heavy. If you punch bullet info into a ballistic calculator, you will see that heavier bullets are going to retain velocity at range, but more importantly energy. If you are looking for a long range bullet, I'm not a believer in Barnes. Not because they are a bad bullet, but because they require more velocity to open up than a traditional bullet does. However, shooting a 300WSM, you should have enough speed with the 168 class bullet to get reliable opening at good range.

I'm a huge fan of the Accubond bullets, they have always worked exactly as advertised for me. I have used ELD-X and been happy. However, I have seen where they don't expand all that great at slower velocity (watched gel stuff at 700 yards, they penciled through).

I currently use Berger bullets, and for the first time using them, at 150 yards, they do more damage than I have ever seen (big doe whitetail). From watching online, they seem to do excellent long range performance, thus why I tried them.

I wanted to reduce the recoil on my 300wsm so my kids could shoot it. I picked up some Hammer 124 grain copper bullets and reloaded with the minimum charge weight powder. I can tell you that there has been more than a few elk that never noticed the light bullet. And the recoil is super fun now.

Now I will add that this set up is out of velocity at around 500yds. I know this because I killed a cow at 550 and the bullet didn't expand. She died but the bullet penciled through.

So pick a bullet and keep them fast. Weight will not matter in my opinion.

I was looking at the 168TTSX, trying to research load data out of 20" tubes seeing if I can get them above 3,000 fps

I'll let you research that one.

But I will just reiterate that you shouldn't be afraid of dropping to low weight copper. As long as you know your range limit/velocity limit.

I guarantee you can get over 3000fps if you go lighter weight bullet. Try it for fun if nothing else.

Any bullet than holds together more or less in one piece is going to benefit from well anbove minimum impact velocity to open up well. Short-ish to medium-ish distances often benefit from light to medium weight for more dramatic internal damage, but eventually the heavier bullet catches up.

Sometimes it almost doesn’t make a difference - my 300 mag can shoot a 180 gr Accubond faster than a 200 gr, but at 600 yards the velocities are essentially the same. Between the muzzle and 600 yards, there isn’t enough of a difference to matter in velocity, and there’s plenty of energy with either. I should like the 200 gr better, but the 180 has a long reputation that’s hard to argue with and any difference in penetration is minimal. In my mind it’s a toss up at my max distances.

Copper bullets penetrate so well, there’s no advantage to heavy weight unless there’s a velocity advantage at distances way out there.

Wow. What a question. Goid ?

I always felt it had to do w velocity and bullet design. Get a V in the magic expansion range of BD and everything works well. Too slow and less ecpansion (no such thing as penciling thru) and too much V and catstrophic expansion.

Far as i know coppers get loaded for length and not necessarily weight (lighter than lead). I found my guns and I, like okd stule cup & cores better.
