Mauser?
8mm, .303, 30-06, 7.63 and .223 will all take down a deer.
It is Against the law in all 50 state to use full metal jacket for big game. Praire Dogs and Coyotes can withstand the FMJ their tough!
Get some soft point bullets in your favorite caliber and keep your shots at close range 100 yards or less is good with iron sights.
5 shots is the limit for all auto loader and bolt action and pump action rifles in most states. Lever actions cal hold as many as they take. Plug your magizine.
I have never seen nor used more than 2 shots being needed to take down deer. If your blasting into the forest you need more time at the range.
Once your deer is down, cut its artery to bleed it out . If its not quite dead; wack it in the head with a piece of wood to knock it out or shoot it in the head if you really must.
MOOSE: Allways make sure thir Eyes are wide open. If they are closed thaey are not dead. Before gutting the moose. Rotate each leg fully to break any stored kinetic energy or it may hoof you to death even dead. Cut its spine at the neck to sever synops.
Just like shooting Sharks. Never bring one in the boat until you sever its spinal colume.
Know your target and know what you will kill if youu miss.
OK I Was temporaly confused by the facts. You CAN USE FMJ bulletts in some states on some game some of the time.
I dont know why you would want to?
Magizines must Permantly be changed to accept mo more than 5 rounds. and one in the tube. total of 6 shots.
Now Im regreting not buying the 2 nice 8mm Mausers from a friend that went through a divorce. He was only asking $50 each so his wife would not get them.
