I am looking for some feedback regarding the .458 Win vs. the .450 Jeffries. I have a .458 in a Whitworth and I would like to get more bang for my buck so to speek.
Question: Will the action handle the new cartridge?
Question: What is the best choice to make in regard to caliber.
I have hunted Africa with the .375 H&H and am after lion this time. The .375 is more than adequate but I am interested in at least a .45 caliber. Thanks Marc

wait a minute!!!

there is no comparision between the two, other than bore.

458 win
.530 case head
2.5" brass
CHEAP brass like 30 cents each
will hold at least 3 down in a normal gun (read-mauser, winchester, etc)

450 rigby (or 460 weatherby, only difference is pressure, belt and shoulder, same root parent brass)
.620 case head
HUGE brass
$2 bucks each, at least
can only fit in a weatherby, cz, or magnum mauser, or other $$$$ actions
lowest pressure of all the 45 cal bolt guns


alternate.. run a 458 lott reamer into your 458 win chamer, open the bottom metal, and go shoot

What is a ".450 Jeffries"?

A .404 Jeffery necked up to .458?
A .460 G&A?
A .450 Vincent Short or Long?

Marc,

Do you mean the .450/.400 3" Jeffery or the .450 Nitro Express?

Thanks for the information. Maybe I should have done a little more homework before posting. I love to hunt but don't keep up on the cartridge and ballistics end of the business. I don't even reload. Yet........ What is a .458 Lott and what is the difference. Sounds like good lion medicine. Thanks for your comments. Marc

A .458 Lott is a full-length .375 case necked up to .450. It requires a .375 length action. If you have a Remington or Winchester, no sweat, but if yours is a Ruger, it's too short. It's a great anything rifle, fully equal to the old, great .450 NE that kills anything that walks. 500 gr. at 2200+ fps is all you need. Make it weight about 10.25-.5 lbs with a fat pad and go to town. If your action is suitable, it's an easy $250 rechamber job by a competent smith.

Now if you happen to have a old Brno .458 then you can do the .450 Rigby conversion like I did. In fact, if you have a .458 Ruger that's too short to convert, sell it and my .450 Rigby can be had for an easy grand. It's got all the bells and whistles anyone could want and I'll lose a bundle on the job but I still want Perry's Pedersoli.
