I own the 458 American Safari Lott and I have shot the 550 bullet at 2210 Fps with it.

With 200 more grs I could probably get it up to 1900 or maybe 2000.

jro45,

Have you taken game with 550 grain hardcast bullets?

If you have any interest in hunting with some 720's, let me know. I'll provide the bullets.

The only game I've taken with a 550gr. .458 bullet is a single wolf and large 6'4" black bear. The wolf collapsed on the spot, shot through both lungs, and as the black bear was drilled through the side of it's head, it did likewise, only much more dramatically. The head hit first, then the butt came down from 3' in the air and slammed the ground behind. The smack in the head with that flat nosed 550gr. Kinda flipped him sideways with his butt going up then smalling down. I know the bullet didn't do that but that's how it looked. Wierd muscle reaction, I presume.
; My 550gr. load was travelling only 1,850fps. muzzle vel. and the bear was 40 yards distance, wolf about 75 yards.
: Cast bullets are fun - especially big ones.

Were do you get those bullets? How hard are they? I would like to try them in my 460 Weatherby.

Thanks
Mark

Hi Mark,

I've tried them in the 458 Win Mag, and like them, as much as I can like that sort of recoil. Will you please post your results and thoughts after you shoot some? Thanks.

I would be glad too. I just need to get some. I have no trouble getting the 600gr Barnes original to 2450fps. I believe we could get this 720 cast to 2000fps!

Mark,

In the 458 Win Mag I was able to get 1600 fps pretty easily, but 1700 fps got me into excess pressure. At these levels recoil was brutal in the Ruger #1. I'll be interested in your notes.

Mark,

Kevin Mazza (kevinm@knmentertainment.com) is the only source for them. If he won't help you, I have a few left that I will send you. Send me a PM with your mailing address after you try to contact Kevin.

Bramble, is 1.3" so bad for a "stopping" cartridge with iron sights at 50 yds ?? Apols if I
am either ignorant or just a crap shot. Why would I have interest in what a .458 WM can do at 200
yds either ? If you want to shoot something big at 200 yds wouldn't a .375 be a much better choice ?I don't get this thread at all..why shoot a 720 grain bullet in a .458 ?? baffling to me. regards, Mike

I did it because the fellow who made them asked for a volunteer. I'm not sure there is a practical reason for it. Certainly 500 gr bullets work well on large game, but it was an interesting experiment. Recoil was brutal, and I have no doubt it affected my accuracy.

Well mike,

I butted out of this thread early on because I could see it becoming one of those 45-70 things but as you asked me a direct question I think you deserve an answer.

For 50 yds I imagine off a rest I don't think it is so hot. I don't think I own a rifle that will not go hole touching hole at that range off a rest. Of course I have no way of knowing what that particular rifle will do with a normal load, or how good the shooter is, so to be absolutly fair I should not have criticised the load without that information. But I believe without going back that it was shot by a regular contributer who is a good shot.

That's 50 rounds in 5 30 second strings one after the other, off hand, open sights at the same distence sorry about the fliers but that was me and not the rifle or load.
I have never shot off a rest at that distence apart from regulation and I have no rested pics at that range.
It is not a stopping rifle, but I don't see that as an issue, if, the cartridge is balanced with the weight of the gun. That is one of the reasons that I so dislike way out of the envelope loads, because the punishment the firer recieves prevents good shooting.


That is a 9.3 off hand at the same distence


Why would you want a .458 good for 200 yds.? IMO because if that is what you happen to be carrying when something pops up then it has to be able to do the business or you must pass. I have shot pigs at 100 ish in the company of another forum member whilst carrying a 450#2 double and use the 9.3 on plains game 100-150 with open sights again with a forum witness.

Look at it this way, if the best that one can do personaly, is hold the sights to within a 4" circle at 100 yards, then if the rifle shoots 1"@ 100 then at worst you will be 3" from point of aim. However if that rifle shoots 3" groups at 100 yds then at worst you will be 5" from where you want to hit that beast. To me that makes a difference.
I have just doubled the group sises from 50-100. IIRC Daryl suggested that a 1.3 50 yard load will shoot much larger groups than 3" @ 100.

There is no such thing as a "crap shot" IMO. If a person is not the greatest shot in the world but works within his boundaries he may be a fantastic hunter. I'm a crap golfer (22 Hdcp') but you wouldent want to have a fiver with me coming down the 18th The only "crap shots" IMHO are those who will not accept either their limitations or the limitations of the rifle that they are carrying and wound game as a consiquence.

Regards

Bramble,

Just when you though this thread was dead and buried, up it comes form the sweetwater to haunt you.

Oh hell Bonanza, I am just a grumpy old sod I have come to the conclusion.

People do not shoot overpowered for weight rifles well.

I am not the "cartridge police" and people can shoot whatever the heck they like I guess. I just dont get making something like this and giving it to your friends to test based on some extrapolated data. Some of the guys making this stuff are very talented. I don't understand why they dont build a universal reciever (they are so easy) and get a couple of piezos hooked up to a laptop and do the job properly.

I love experimenting with stuff. I just spent 2 days hooking a reduction gearbox and drive cogs up to my Bridgeport so I can cut spiral octagonal barrels, for no better reason than I figured out a way to do it. (Heaven help whoever has to stock them)
I've got 2 98 Mauser 318WR nearly finished on the bench without a customer for them just because I like the cartridge. Heavens knows when somebody in London last did that, because the proof house had to order in cartridges especially for them.
I bought a box of 40 pairs of back action hammer locks just because they were there and now have to build some rotery underlever actions to suit them, how arse about face is that

So I really do see the bug for doing something different, but the lead slug thing has been done to death for no benifit I can see and this one was so under tested that it riled me.

I butted out because I dident want to offend anyone, I still do not think that I am wrong.

So make that grumpy arrogant old sod.

Best Regards

: Bigger/heavier has always been better.
: Overall cartidge length numbers are pretty much imaterial to someone who is an ackomplished handloader. That length is good only for one rifle, anyway, the one that load was developed in. Rifles have different throat lengths and even throat angles, different leade lengths, and some have a freebore condition, allowing even longer overall lengths and therefore all require different load data to develop identical pressure. Mine were all cut with my own reamers - someones else's data is merely data I can reduce a safe amount, to develop my own data from. Published data is a starting point only for the devlopment of one's own data.





Daryl;

Your last paragraph should be published in every handloading manual!

I write on these things and essentially that's what I have to say. One thing I know from experience, after a half-century of hunting with a variety of rifles from .223 to .458, is that big-bore rifles work best FOR ME! And, hardcast heavy bullets in .458" (yes, Mr. Bramble, FROM A 45-70 as well as a .458 Win Mag)will flatten anything on this continent! And, from what I read... in Africa to boot!
