For those wanting/needing a lead-free, HEAVY 357 Magnum load, generating full power plus, here it is.
Due to the long-for-weight all copper bullet, the 357 does not have the case capacity to use a bulky flash retarded powder and thus there is a noticeable muzzle flash with this load in all the test revolvers;Â however, the rifle shows no flash at all due to its longer barrel.
This load is the typical barn-burning, turbo-charged, Buffalo Bore type Heavy 357 Mag. load and as such, should only be used in revolvers made of all steel. It should not be fired in lightweight, alloy framed or cylindered revolvers. Feel free to use it in ANY/ALL 357 mag. chambered rifles and all steel revolvers/handguns.
