Re: Which bullet for big game (300. win mag)

IMO you are doing a great disservice to your 300 mag when you settle for using less than a .630 BC bullet, especially at long range. The 300 Win. has the capability to fire heavier bullets fast enough to get the full benefit of the high BC of the heavies. The average 180-190 grain bullet carries around a .500-.550 BC, which at one time wasn't bad, but you have many more options to utilize the the cartridge for what it was intended for and that is to carry energy to greater distances than cartridges like the 30/06.

Although you can be effective with the 168-190 grain loads at higher velocity, in most cases the average hunting bullet pales in comparison to high BC bullets in the 300 mags due to two extremely important benefits #1 wind resistance and #2 energy delivery.

For long range shooting BC is king for several reasons. Although, your muzzle velocity will be lower with most high BC bullets because of the heavier weight associated with them your downrange energy, and wind bucking ability will more than make up for the lack of velocity.

For instance, let's look at the average 180 .505 BC fired at a velocity of 3100 fps, elevation 5000 ft, at 700 yards distance, retained velocity = 2115 fps, and energy at 1788 ft lbs, wind drift with 10 mph full value wind = 3.50 MOA or 26.2 inches

Now take a look at a high BC Berger 215 hybrid, .696 BC at 2850 fps, 5000 ft, 700 yards, retained velocity= 2133 fps, and energy of 2172 ft/lbs, wind drift with 10 mph full value wind = 2.75 MOA or 20.3 inches

And this is only at 700 yards, the numbers and benefits only get better the further out you get.

What was the problem with your Kreiger?

Just started using the 210 Bergers out to 1000, and gun is sighted in for them, but will probably have a few Barnes 180's in my pocket for close shots.

It shot 1 1/2 moa even after 100 rounds of wasted time and compoenents. The Broughton shot 1/2 moa with ease and a load was found quickyl. I have Keigers that shoot very good, but I believe I simply got a bad barrel.

Re: Which bullet for big game (300. win mag)

Accuracy loads out of my 300 winchesters at sea level 100 yard zero.


180 Cutting Edge C21 at 1000 yards. drop 218", windage 57", 1791 fps, 1282 ft pounds.

210 Berger same parameters. Drop 273", windage 62", 1619 fps, 1222 ft. pounds.

What disservice?

The primary difference would be the energy with the CE 180 bullet would be very close since it retains around 95% of it's weight as a premium hunting bullet. The lead core bullet, of whichever manufacturer, depending on what velocity you hit the animal could lose quite a bit of weight therefore making energy figures with it useless.

This is a hunting forum and not a target forum so one thing hunters with limited experience need to look at is not using a bullet that exceeds the capability of your cartridge where range is concerned. Shooting targets at extreme long range well beyond 1000 yards a shooter would benefit by shooting a much heavier and greater BC bullet since killing performance is not a concern. A heavy for caliber bullet such as the Hornady Amax, Sierra matchking or Berger VLD for instance. But with hunting you must look at other parameters such as what is the top range my cartridge would be acceptable on big game performance. Then look at the best bullet for big game performance within that range. Also a bullet that performs well on game at 50 yards at high velocity and then at 1000 yards at slow velocity. 1000 yards is about where a guy should limit the 300 winchester and maybe closer on elk size game. At that point he should look at a cartridge with more performance.

Killing animals at long range is far more than just picking a bullet that looks good on a ballistics program.

I just wanted to come in here and add another important factor. I use my 300 winchester as a light backpack style rifle good to somewhere between 800-1000 yards. With the 180 grain bullet it is a pleasure to shoot and I can easily hold steady on long range targets with it. With heavy bullets it will knock the living crap out of me. I do not want a muzzle brake on this type of rifle. If I use a muzzle brake or heavier rifle it is in a cartridge with far greater capability for long range hunting than a 300 winchester. The set up I use with the 300 winchester is excellent for a light rifle to 800-1000 yards. Scoped out it weighs 7 1/4 pounds. If I went with the heavier bullet that knocked the crap out of me then I am defeating the purpose to begin with and am going larger cartridge. If I shoot a heavy rifle I may as well shoot it in something with 1500+ yard capability. No difference in weight or hiking with it. My equipment is highly refined for a particular purpose when I pick that particular rifle up to go hunting.

Re: Which bullet for big game (300. win mag)

So, you call a lathe turned copper bullet, with a hole drilled in it, a premium hunting bullet? They've only got 2 pictures (that I could find) on their website of bullets recovered from animals. One banana peeled and the other didn't do much besides flatten the nose. I'm not saying they don't work well, but to call them a premium hunting bullet might be a stretch.

My brother-in-law shot a mulie last year at 1400yd with the 252 CE bullet. The deer not got out of its bed. One shot and flop went its head. As far as I am concerned, they work.
