"Recommended" is hard to say. There are countless "knowing ones" posting on boards or writing in the rags about this that honestly have little real idea what they are talking about. I have had it said too often to count that the muzzleloaders in general are "short range only" guns or only "marginall effective" guns for deer. I have even had a woman come in to my store after sage-advice from her more knowledgeable brother to buy a .50" muzzleloader-kit (May have been a Bobcat for that matter) for her son so he could play with it in the off-season and he could shoot it at his friends playing without harming anyone.


Fact of the matter is of course that each load has different penetration characteristics in each gun and every shooter is different with every different load/gun. You need to work up the most reliably accurate load for the gun. Then, test that load at different ranges first to see what your maximum hunting-accurate range is and then test it on a good medium for reliable penetration. Personally, I like tying phone books together to make a dry stack that is about 4"-6" thick then soaking them overnight in a bucket of water. Stand it up and shoot it to see what sort of penetration you get. If you get 100% penetration you have a very lethal deer load at that range. You can stack multiple books behind each other and see just how deep it will penetrate and often times even catch the bullet to see what sort of deformation you get.

If the bullet will penetrate 4"+ of tied and wet phone book you have enough inertia/velocity to penetrate the 1"-2" of broadside hid, meat, rib to enter the near lung which is essentially hollow, then pass through to the off lung and probably pop out the off-side of the deer, or barely get stuck under the off hide. Either way, you have poked a .45" hole through both lungs and even an elephant won't go too far with its lungs collapsed like that. With a little ball pushed by "just" 60 grs of FFFg you ought to be able to get about 100 yds range and with a conical you can get about another 50 yds range to be reliable on deer with broadside hits. My own .50" Hawken with a "poky little ball" as is oft described by the "knowing ones" in the gun rags will give reliable full penetration with 70 grs of FFFg through the phone books at 200 yds. I have not shot a deer at that range to test it on meat but I have no doubt that at 200 yds that "poky little ball" will put meat on the ground regardless of what the writers touting the latest and greatest super-duper-ultra-magnum-disc-fired-electronic-ignition front-stuffer claim.
