From his very thorough velocity, accuracy, and expansion tests of a number of bullets,
(See these amazing test results! Click here!)
we'll start this page with the excellent workup done by David White.

Note that:
cases used were Remington, and
primers used were Remington 7 1/2 benchrest rifle primers.

Other notes:
Maximum velocity for all 125 gr. bullets tested was 2,700 to 2,800 fps....

Maximum velocity for 180 gr. bullets tested was just over 2,400 fps....

With the Hornady 140 gr. FTX bullet, I safely got 2,700 fps....

Compare a 180 gr. bullet coming out of the Max. at 2400 fps (+) against a 180 gr. bullet coming out of the .308 Win. at 2400 to 2500 fps.

Both produce approximately 2400 foot pounds of energy at the muzzle!


The 180 gr. .30 cal. bullet has a much higher ballistic coefficient and will drop less at longer ranges than the 180 gr. .35 cal. bullet will.

The .30 cal. will also arrive at the longer ranges with more energy albeit making a smaller hole and potentially less than ideal bullet expansion.

On the other hand, most of the lighter .35 cal. bullets are much more lightly constructed and designed to expand at lower velocities.

What the .357 Maximum gives up in trajectory and energy at, say, 300 yards, it tends to make up for with a larger wound channel.

Perhaps we have been selling the .357 Maximum short by calling it a 200 yard rifle cartridge, and 300 yards may prove to be quite realistic for it. Time and your experiences in the field with the Max. are the factors that determine what its maximum effective range is, no pun intended.

Handloads.com .357 Max load data
Excellent listing of .357 Maximum loading data, some of which is pressure tested, along with some interesting comments about the effectiveness of the .357 Maximum.

Accuracy and expansion results examples:
Picture perfect expansion!
Energy at 200 yards, 803 ft. lbs., compares to 100 gr cahrges from .45 cal & .50 cal. muzzle loaders at this distance.

100 yd. zero / 8.1" low at 200 yds
Very Impressive 250 yard accuracy!
