Shootall, Didn't know they made target bullets in 40 and 45 calibers.
Now, I am and have been a Nosler Partition lover for many years, and think they and the Swift are A-OK.
However, one thing the current crop of Professional African Guides are a bit short on is experience with good cast bullets - HEAVY w/WFN.
One of the writers went to Africa a number of years back, and the guides had all kinds of reservations about his use of a 45/70 w/cast bullets until they saw the results first hand.
No more questions, just awestruck at the results from a cartridge first used well over a hundred years ago.
Newer and better bullet designs/profiles/alloys make this into something other then a 1873 discussion.
If you folks will go to Garrett Cartridges Inc. and read some of Randy Garrett's info as per big bears and a 45/70 w/ WFN cast bullets, you can see conformation of what I've been trying to get across.
Randy will greatly enlighten you as per velocity and quality cast bullets.
Note that Randy also makes comments as to bullet profile and the problems with bolt actions as per feeding bullets with the most effective profile.
As per an earlier posts about needing to break down a nasty critter, NO QUESTION THERE, but if you can't believe my comments about a heavy hard cast WFN bullet being up to the task, you need to do a bit of research into the subject.
A properly cast WFN of the proper alloy is up to the task of breaking down any bear at any time and from any angle.
Check out the results on the big African buffalo. Do a search on Marlin Owner Forum or Cast Boolits Forum.
I didn't really believe some of the info myself, until I tried it for myself. It just seemed to good to be true to this old jacketed bullet loader/shooter/hunter. However, everything I have read about good WFN cast bullets in a good cast bullet caliber - bigger is better - is 100% true in spades!
You may never buy into using and casting your own bullets, but you own it to yourself to do a bit of research. It very likely will surprise you if not make you a convert.
