.300 Win Magnum vs. .458 Lott

17 June 2006, 03:07

In Rifle Magazine July 2006, there is an article entitled .300s and .338s . The article asserts that at 500 yards, the .300 Win Mag with 200 gr bullets has 1884 ft lbs of retained energy and drops 37 inches with a 200 yard zero. The comparable figures for the .338 Win 210 gr is 1736 ft lbs and 41 inches.

500 yds.

The difference is even less sitting in your pocket....only a few grains difference. Velocities and energies are the same there as well.

Seems like if you are going to compare calibers and choose a heavy-for-caliber like the 200 gr bullet in the 300 win mag then you should compare it to the heavy-for-caliber 250 gr 338 win mag bullet.

I love my 338 win mag and would choose it to Elk hunt, but I have always been able to get more theoretical energy and a flatter trajectory withe the 300 win mag rather than the 338 win mag.

Example of my hunting loads which in my guns are close to max:

caliber / bullet weight type / powder weight type / MV / BC / 500 yd energy /500 yd drop / 500 yd wind drift / sectional density

300 win mag / 180 gr TSX / 76.5 gr RL22 / 3123 fps / .552 / 2166 fpe / 31.9" / 13.37" / .271
338 win mag / 225 gr TSX / 75.5 gr RL19 / 2835 fps / .482 / 1977 fpe / 42.8" / 18.23" / .281

300 win mag / 200 gr Accubond / 79 gr H1000 / 2950 fps / .588 / 2202 fpe / 36.5" / 13.6" / .301
338 win mag / 250 gr TSX / 75.5 gr RL22 / 2760 fps / .521 / 2186 fpe / 44.3" / 17.3" / .313

If I were going to compare a bullet in the 300 win mag to the 210 gr 338 win mag bullet, it would be the 168 gr TSX. Unfortunately, I haven't shot enough 210 gr 338 bullets to form an opinion. This is my load in the 300 win mag 168 gr:

300 win mag / 168 gr TSX / 75 gr IMR4831 / 3282 fps / .478 / 2052 fpe / 30.7" / 14.8" / .253

All that being said, I would choose to shoot an Elk or Moose with my 338 win mag over the 300 win mag.

Guess I'm a member of the H B M (heavy bullet mafia)

The only somewhat accurate BC number in the above is the AccuBond number. See Barnes' updated (and finally accurate) BC's HERE.

That said, I agree with you:

I've got a small truckload of 250 grain .30 calibers on order as we speak....
