...since S&W convinced SAMMI to water down the VOLUNTARY pressure standards for the .357 Magnum in order to usher in the era of the small (J) frame .357, only smaller ammo companies truly cater to the L Frame and larger handgun hunting market with top velocity ammunition.
It is time for a full power +P standard to be adopted by the Sporting Arms and Manufacturers Institute for full size .357 Magnum revolvers.
The primary reason for the .357's poor reputation on deer size game is the use of JHP ammunition designed to limit penetration for LE/self defense use. This is also why the WFNLGC hard cast bullet has developed such a following in this caliber. A .270" to .300" meplat (flat nose) in hard cast bullets in the 175 to 200 grain weight range driven at speeds from 1200 to 1400 fps (4" to 6" barrels) are superb deer rounds at moderate (up to 100 yard) ranges. Heavier WFNLGC also have the advantage of reduced muzzle blast.
Interestingly, two of the most popular lever action deer rounds of the late 19th and early 20th centuries, the .38-40 and .44-40, drove similar weight/meplat size bullets at the same velocity as todays full power .357 hunting revolvers.
Final point, the recoil level of the .357 even with heavier bullets is easily controled by the average handgunner. This makes for better bullet placement under field conditions with this extremely popular round.
