How does the 470 mbogo compare to the 458 lott in recoil and stopping power.

like a one-ton Dodge Cummins Turbo-Diesel to a half-ton gasburner ford.

JMHO from data available from Mbogo

Rich

both are 500 gr bullets
both can be loaded to 2300
both can be in 9.5# rifles

and both are fine to shoot at 2300...

and 2500, wel, the lott is steel rain and the mbogo can be shot 3 times in 5 seconds at a running eland from 180yards, hitting it every time...

ask Dave and Chis!!

Hi Capebuf
The 470 Mbogo is designed to shoot a 500 grain bullet at 2500 fps with moderate pressures. RIP has loaded his uo to 2690 fps but that is not the idea behind the cartridge but it does show that it's breathing pretty easy at the 2500 fps velocity. The 458 Lott is designed to reach a velocity of 2300 fps. Keep in mind that a 500 grain bullet at 2300 fps is a very powerful cartridge. Everyone is always talking about the magic 2400 fps but my idea was 2400 fps at impact not the muzzle. With a starting velocity and the ranges most dangerous game is shot at the initial shot would fall into this impact velocity. Starting off at 2500 fps with modern bullets you would gain in trajectory, impact energy and bullet surface area over the Lott. A 470 Mbogo should be built to 10 or 10.5 lbs. with a straight inline stock and a good recoil pad such as the Pachmayer F990 to be comfortable to shoot. You should also with your Lott or the Mbogo install a second recoil lug as well as a good cross bolts to ensure your stock structure is sound.

As far as stopping power the 470 Mbogo generates close to 7000 ft lbs of muzzle energy and if you put the bullet where it's supposed to go it will do the job. I shot a Cape Buffalo facing straight on half way up the chest and recovered the bullet back at the pelvic bone. The bullet was a 500 grain Swift A-Frame and was mushroomed out to .850. I'm sure if it was a solid it would have exited.
Take care,
Dave

I have a 458 Lott and I have shot Dave's 470 Mbogo this last Nov.

On recoil, my 458 Lott 9lbs 12oz, 500gr/2300= 73lbs recoil. Dave's Mbogo, 10lbs (I think)500gr/2500= 90lbs recoil +/-. If you can take the love tap and put your shot where and when it needs to be, then get one.

The biggest advantage for the Lott, is that it is much cheaper to feed; bullets, brass, dies, powder, etc. Factory brass is avalible, the selection of bullets is greater, and if you do not handload factory ammo.

Dave's Mbogo is a great round for those who can handle it and are willing to go the extra steps to feed it.

That's right Dave.
One more grain of RL-15 would have gotten me 2700 fps with 500 grain Barnes Original RNSP bombs.

I backed off to 2500-ish fps MV with the Barnes XLC and GSC FN's.

I SWAG a 2500 fps load is in the 50 K PSI ballpark right where you want to be.

An interesting fact about the .470 Mbogo is that it has case capacity almost identical to the .470 NE, and tougher brass.

One could use the George Hoffman Memorial .470 NE load in the .470 Mbogo:

110 grains of H4831SC with 500 grainers ought to get you about 2150 fps, and a very gentle, accurate and effective load.

No fillers needed.

Thanks for the suggestion RIP. I think I'll try that as a practice load.
