Do you understand WHY we generally recommend using a Patched Round Ball( PRB)???
Generally, MLers are shot using open sight. The limitation of such sights, and the ability of the shooters to shoot small groups using open sights is such that 100 yds. is a long distance for shooting at game.
The Whitetail deer is by far the most common big game animal hunted using MLers. It is a thin skinned animal, with relatively small, thin bones.
A PRB will complete penetrate the body of a whitetail deer on any kind of broadside shot out to 100 yards and further, assuming you are using a .50 cal. or large diameter gun. PRB can be shot accurately out of any ROT barrel, while conicals generally require a faster ROT, and usually, shallower grooves than are cut in a RB barrel. If your NE MLer is .50 caliber, but has deep grooves, ( .010"-.012" deep), and a ROT rifling of at least 1:48", then it is really intended to shoot the PRB. If the grooves are cut shallow- .005 approx.--- then its intended to be used with a properly sized conical bullet. Some short conicals like the LEE R.E.A.L. bullet are specifically designed to use in these "slow" twist barrels( 1:48 or slower) Sometimes they get great accuracy using these conicals. You will feel more recoil using the heavy slugs.
Most of us feel its more important to accurately place your ball or bullet in the game for a clean, quick kill, than to miss it, or hit it in the wrong part of the body with a monster bullet. For most shooters, you are more likely to practice shooting your gun before the season opens, every year, if you are shooting PRB, which are lighter in weight, and also cheaper to shoot, than if you are shooting conicals( bullets) out of the gun. Practice is required for accurate shooting when hunting.
FINALLY, the main reason re recommend the PRB for hunting, is because a PURE LEAD BALL will expand even at very low velocities. Compared to a modern deer rifle caliber, such as the .308 Winchester cartridge, instead of beginning with a .30 caliber hole in the der, you begin with a .50 caliber hole! That .30 caliber bullet won't expand to .50 caliber in that deer. The .50 caliber ball, going much slower, however, will expand to approx. .75 caliber, or larger going through the deer, leaving a HUGE PRIMARY WOUND channel, compared to what is left by that .30 caliber bullet.
Now comparing that conical bullet to a PRB, you rarely get any expansion at all with conicals, unless they hit a very solid bone. Until you get to the Old Mule Deer, or Elk, Caribou, and Moose species of the deer family, you won't find bones heavy enough to expand those conicals. So, you are left with a .50 caliber hole. NEXT, some conicals have a terrible reputation for diverting from the POA( point of aim) and veering off in another direction as soon as they hit flesh. The Round Ball, having no edges, keeps going straight in line with the POA, with notorious regularity.
If you put your sights on a deer, where vital organs are behind your POA, those will be the organs damaged by your PRB. All you need to do is bone up on deer anatomy and make that one shot count, and you take home meat.
The bottom line is that a conical is expensive, gives more recoil, and is just not necessary, or desirable to use when hunting Whitetail deer. Hunt Wild Boar, and now the conical comes into its own, and is superior to the RB, unless brain shots are taken by both. Hunt Black Bear, and shoot any bear over 250 lbs., and the conical is probably the better choice.
Its your choice, of course. I personally believe that you will shoot your gun more, and enjoy shooting it more if you shoot a PRB instead of the conicals. :thumbsup:
