From what I understand, the military FMJ's are "generally" long for their mass & only just stable when shot from their correct "parent" rifle. Once the Hague convention outlawed hollow points for other humans in military conflicts, the military had to come up with another way of causing a big wound channel in "other humans". When a projectile is "spin stablised" as from a normal rifle, the projectile is generally spinning on it's axis very fast.
If used for hunting at close quarters they tend to go straight through but given some distance, maybe 200 - 300m, they should tumble (also the given is, they strike a body similar to a human).
Some (back in the 1950's & 60's) did 'cut the tip off mil. issue FMJ .303's & go hunting but this could then blow the aluminum & lead core through the CuNi jacket, leaving the jacket in the bore.
For this to happen I suspect you would have to have a tight, fouled barrel & be using the full Mk7 load. Others have pulled the projectile & removed 2 or 3 strands of the cordite, to lower the velocity & pressure, then reseat the projectile & claim this stops the 'blow through' of the guts of the pil.
I have not witnessed a 'guts blown out of jacket' by cutting off the tip - yet but did see the results of a blocked barrel - not nice.
Think about it, the projectiles are designed to do a particular job & while FMJ's can be used for hunting, just be careful with shot placement & animal choise.
Experimental:
Another way is to pull the pil on the mil issue stuff & substutite a lighter HP pil, shouldn't be an over load - maybe measure the powder & remove 3-5% & test, as with all reloading, work up from a starting point.
From here on it's up to you.
