I don't think a 357 max will approximate a 35 Remington.

Spanky,
Tim likes his super 35 specifications and uploading older rounds like the 35rem to its true potential is a nice way to reinvent a grand old caliber like the 35 Remington or the 257 Roberts or the 32/20. These where created in a time when steel used in our firearms wasn't what it is today and the firearms designs wasn't up to the strength of today's actions.
BUT the statement was made that the 357maxi can approximate the 35 remington ballistics... Well I'll tell you that if you compare the 357 maximum loaded to SAAMI specs and shoot it in a rifle barrel of the same length as a SAAMI spec loaded 35 remington... the 357 maximum will slightly exceed the grand old 35 remington. My maxi with
under a max load of 1680 powder and a 180 hornady SST bullet will net me just over 2200 fps. This same bullet from a 35Remington moves along at just under 2200 fps. Now its not enough to crow about, but in the finite, finger pointing world we live in, the maxi exceeds the remington. Remember, the maxi is a pistol round, loaded to much higher pressures created in 1983, while the 35 remington was created over 100 years ago for a semi automatic rifle. So just putting a maxi into a longer tube gains you 400+ fps. Modern powders and careful loading gets you even a bit more.
SO, YES the 357maxi approximates the ballistics of the 35 remington... it even exceeds it!!
