This is a fun thread, and there is no right or wrong choices, its about what you would choose. But it has to go beyond just the "Cartridge", there has to be more to it than just that one component. How about the platform/Rifle? How about the most important component, the bullet? I think you have to consider these two components to come up with a proper decision.
Cartridge for Dangerous Game............
Well, this narrows the selection well...... not a cartridge that is capable of doing other jobs, not an all around cartridge, one that is barely or not adequate for dangerous game, but good for impala and white tail deer too....... No, Dangerous Game only cartridge, no other considerations involved.
Dangerous game will have at the top end buffalo, hippo, and elephant. At the bottom end a 125 lb leopard....... in between lion/bear and throw in the odd crocodile I think as well.....
You have to plan for the biggest of this category, not the smallest. What might be perfect for the 125 lb leopard, probably won't be for the elephant. What is perfect for the elephant, can be made do for the 125 lb leopard with proper choice of bullets........
When considering elephant, buffalo and hippo, Caliber of the cartridge is important. For me, that starts at .458 Caliber and I think optimum at .500-.510 caliber. Rifles that come in larger calibers are just more than I want to carry around all day long, and I think are more cumbersome for me to put to work quickly if required. I love .458 caliber, it is more versatile overall than the larger .500-.510s....... Any of the 458s would be a dandy choice............ 458 hits harder than .416.......... and in the same view .500 hits harder than .458. I have not seen any difference in this between .458 and .474, but have seen differences in 458 to .500.
For caliber, I am going to go to .500 caliber to hit the biggest, the hardest. I can make some bullet choices down from there to sort out the lesser size DG.
Now, What 500 caliber Cartridge?
What rifles do I have personally that would meet my requirements?
I have in hand a giant 12lb Ruger Magnum in 510 Wells..... .510 caliber, can easy shoot 570 #13s at 2400 fps +, long musket barrel of 24 inches.............. No, not this one, it is just way more weight, length than I am going to carry around in the field. It is cumbersome, it is not handy, it is not fast. No, it is out.........
I have 500 MDM, rifles come in with 20 inch barrels, from 8.25-8.5 lbs depending on the wood. Cartridge is capable of sending 500 gr CEB #13 Solids down range at 2400 fps, these will end to end buffalo, easy, capable of 525 gr CEB #13 Solids at 2300 fps, more than capable of slamming all the heavies. Of course in the case of buffalo there are many capable trauma inflicting bullets to start the buffalo dance, followed by the solids....... and these just slam buffalo to the extreme. And while I have put many days in the field with this cartridge/rifle, It only comes in Second on my List.
I have lesser .500 caliber cartridges, 50 B&M capable of 500 Solids at 2150 fps, 18 inch barrel, 7.5-8 lbs, light, and short, very fast, very handy, very easy to work with, and also would not be a bad choice at all for this mission, but for the purposes of this thread, I think I want something in between the bigger 500 MDM and the 50 B&M..............
That in between cartridge comes in with a 18 inch barrel as well, same contour as the smaller 50 B&M. It uses a Winchester RUM long action, utilizes a 2.5 inch RUM case, dead in between the other two .500s........ Standard weight is around 8 lbs. It is only 1/2 inch longer than the 50 B&M and a full 2 inches shorter than the bigger 500 MDM. It is capable of 500 CEB #13 Solids at 2250 fps, 525 CEB #13 Solids at 2170 fps, various 450 gr North Fork and CEB solids at 2400 fps, all of these more than capable of the heavies and hit them hard. Trauma inflicting bullets from 410 gr to 450 gr, 2400 fps to 2500 fps...... rips and slams buffalo into submission. One of the great advantages of using this cartridge, it can utilize Talon Tips in the Raptors and work through the magazine, this Talon Tip adds 125-150 fps impact at 50 yards, substantial with these type bullets.
Rifle is extremely handy, fast, easy to carry all day, handles incredibly well. It is short enough not to be cumbersome, and if needed quickly at very close range, it is a fighter for sure.
I think for ME, I choose what is designated as the 500 B&M, 2.5 inch RUM to .500 caliber. It is not a popular rifle/cartridge, reason is, I never turned it loose like the other cartridges, it was more of an experiment for me personally. There are only two of these in existence, I have both. One is stocked with an Accurate Innovations Bastogne Stock, and the other is an Accurate Innovations Myrtle Stock......... Let me show you my Choice for this Thread;
