Lt Dan, and Wildebees:
Nice to have South Africa residents around the forum.
So, here is my ongoing battle: I have a CZ 550 that I'm going to have rebored. My gunsmith, who just bought the barrel machine, argues for the .458 Lott. I am with Chuckscap, and what to have it opened up to what is really 475 Ackley, the 375 case blown out to .475. Out of a longer barrel, it's supposed to move a 500 grain bullet at 416 Rigby
2400 fps, and, give you a full magazine, of 5-6 rounds, vs. the Rigbys usual 3. The big plus, if you can call it that, is you can move 600 grain solids at over 2150 fps, as well.
Here are my pluses for the .475. Most rounds possible in a serious stopping rifle.
Can move heavier bullets, faster then the 458 Lott. Moves 600 grain bullets at .500 Nitro Express velocities, with better Sectional Density.
I've got about 600 flat point 325 grain 475 bullets laying around. I can push these at 2750, and have my own version of Saeeds' 404/375, but, with a bigger hole, and more rounds.
The bigger caliber would limit penetration, if you want to, with a soft point.
While not the flat out stopper the .500 Nitro Express, or, .510 Wells are, it's pretty near the limit of recoil, and, gives you high velocity with heavy bullets. In otherwords, you have a .475 caliber bullet, heavier, yet with the velocity of the .416 Rigby. A 500 grain soft point at 2400 fps should be the ultimate lion load.
You can neck up 375 brass, cheap everywhere.
Now, the downside is, it's not a .510 Wells, and, the argument for the .510 caliber bullets being the best stoppers is well established. They penetrate better then the larger calibers, and, stop better then the .470's, or 458's. Still, I've never really heard someone say the buffalo ran away with a proper shot from a .470 Nitro Express...
Ammo is much harder to find then a 458 Lott, and, bullets are a bit more expensive.
It recoils more then a 416 Rigby, but, it gives you more shots, and, heavier bullets.
I could go on, but, I just went through this on the phone with Jack Huntington. Everytime I let someone talk me into a lesser caliber, I end up wishing I'd followed my own counsel.
Finally, the 475 can be easily loaded with less pressure, yet give you the same bullet weights, and velocity, as the 458 Lott, without the excessive pressure.
Wildebees: Enjoyed your comments about the buffalo cows. Don't elephant cows act in much the same manner?
Black Mamba's scare the living daylights out of me. Deadly, huge, and fast. NOT my favorite snake combination, and, I forgot the aggressive part.
Don't you find Africa has a LOT of ways to keep the population down???
Lt dan: I thought Ganyana did a write up on PH tests, and, since most of em aren't rich, the most common, and best rifle was a Brno, or CZ, in 458 Lott?
I'd also argue that the BEST caliber for Africa is really the 9.3 X 74R, or, 9.3 x 62. Something about that 286 grain bullet that, if placed right, will kill Dukier to Elephant, with NO recoil to speak of.
Here's me shooting this beautiful little double rifle that feels like a 22, both in weight, maybe 7 pounds, and recoil, yet, it will kill an elephant...
