These loads actually have a bit of the tip still exposed. So I guess its not a FULL metal jacket. But it is jacketed to an extent. Thanks for the heads up moose about the hunting regulations. Never even took it into consideration it being a jacket round. Do fish and game wardens ask to see your ammo alot of the time?
Sounds like you could be confusing these bullets...
FMJ bullets as previously described are covered in a jacket many leaving the base of exposed lead. (NOT ALL BTW) another name for these when used in semi auto firearms is "BALL" the jacket is very thick on the order of 5-10 times as thick... A TMJ is a newer term again as mentioned with the advent of "lead free" loadings. It may in some cases also have a very thick lacket BUT in others its simply thinly covered to contain the lead within.
A SP, HJSP or HP bullet is also jacketed, but the jacket of quite thin, basically serves to stop the lead from staying in the barrel. It also allows the manufacturer to use soft lead that will expand.
Do not confuse these pistol bullets with rifle bullets. Rifle bullets operate under higher pressures and higher velocities. There jackets are tapered, thicker at the base and thinner at the tip to allow expansion. These again have FMJ bullets also these bullets utilize very thick jackets.
If you knew and understood these things, I mean no disrespect, your comment in your last post, made me think you may not know these things.
