A CCI BR4 primer is NOT a magnum primer. The correct one if the spec requires a magnum would be a CCI 250.
The BR4 are a better grade of the 200 for Bench Rest style reloading. CCI does a fussier sort of the parts/materials of the 200 grade primers to meet the reliability specs or so the story goes. Makes for more consistent ignition and commands a tad higher price (about $1-1.5 for the std packages).
Secondarily while the parent Cartridge might be the correct, a .357 mag case is 1.29" but wont stretch to the the .357 max length of 1.6".
If one reads the wiki link one finds out that its an older wildcat for LR pistol silhouette and the only brass available is either Remington or Starline. That puts it in the same genre as the .30 and .357 Herrett rounds with the Herretts being easier to get cuz they are formed from .30-30 cases...
More topically a bit of data for comparison;
Bullet Diameter: .357 inches (All 350 Legend)
Shell Case Length: 1.71 inches (All 350 Legend)
Bullet Size: 180 grain
Muzzle Velocity: 2,100 fps
Muzzle Energy: 1,762 foot-pounds
Velocity (200 yards): 1,466 fps
Energy (200 yards): 859 foot-pounds
Bullet Size: 158 grain
Muzzle Velocity: 1,830 fps
Muzzle Energy: 1,175 foot-pounds
Velocity (200 yards): 1,138 fps
Energy (200 yards): 454 foot-pounds
(Winchester Super-X, 158-grain jacketed soft-point)
Of interest to folks is that the 158 gr is not the classical FN geometry its actually a SP that Winchester developed for the cartridge which sort of changes things as far as ballistics and expansion are concerned. Something I might consider in my Herret loads as a sub for the FN Im currently using.
