I have a 458 win mag I've been playing with. I'm not totally pleased with the accuracy, and I'm sure that is the barrel.
If light bullets could be pressed fast, and still be accurate, then I could justify a good barrel.
If it is just not in the nature of the 458 to shoot light bullets accurately, then I'll just leave the rifle as is.
Thanks.

I shoot 400 gr Woodleighs from my 458 - and I can get 2" groups at 50m with open sights.

I like that.

Now, how to adjust the frikkin' sights ....

I've shot Speer 350 grain Hot Core bullets out of my 458 Lott with good results. They work well on rabbits.

I shoot 300 gr Sierra and 350grain Speer out of my .458 Lott at over 2800 fps with pretty good accuracy. Also shoot Berry plated bullets a little slower with really good accuracy.

Frank,

I have a 20" barrel 458 MK X. It loves the old 350 GR original X bullets and shoots them as accurately as the 500 Hornady. I get 2550 fps and 1" 3 shot groups. I used that load when I lived in AK for moose and caribou. It flat hammers soft skin game. To answer your question in my experience the 458 WM shoots the lighter bullets very well.

Mark

Try some 350gr Hornady Round Nosed bullets over IMR 3031.

They shot accurate in both of the 458,s I had, and in both the 45/70's as well as several friends 45/70's.

They also shoot great in my 450 No2 double rifle.

They work great on deer and pigs from 1800fps to 2350fps.

Another vote for 400 grain woodleighs, not just being an aussie myself I have found they are the most accurate bullet in calibres 458+. The 400 grain was designed by geoff for aussies using bigbores to flatten medium-big game in similar vein to the 340gn woodleigh 416 bullet and 270grain 375 bullet. That is they are used on everything from pigs, camels, horses,goats but still able to take scrub bulls(feral cattle). The only proviso is the philosphophy is more of the bullet 'stays inside the animal and expends its energy' rather than the super penetration trend of today. Generally for volume hunting or amateur culling conventional sopftpoint expansion is preferable as quick kills and especially being able to flatten small/medium game with less than perfect (or to be frank gutshots) is what allows putting large numbers of running game down at one sitting. The protected points expand a bit slower than the woodleigh roundnoses by the way.

At the other end of the scale are all the mono/Super hard premium lead bullets that penetrate from all angles and are more aligned with the US/african style which places a lot more emphasis on taking a single animal.

Apologies for the lengthy post but I am a fan of light fast bullets in bigbores

It seems CEB has a 250gr intended for the 458socom. I imagine you could make it scream in other 458 rifles too.

Drew...... Nahhh.... I designed the 250 #13 NonCon as a double duty bullet. Bands forward to work in all .458 caliber lever guns, and also to seat deep, use the tip, and fit and function in bolt guns. This little light for caliber bullet is extremely accurate, and performs way beyond its weight. I am running it at 2900 fps in an 18 inch 458 B&M, and will be taking it to Africa in July to try out on plains game, target zebra/wildebeast, to see how it does. According to the test work done here, it will be a hammer of a bullet. It was also tested in 45/70 lever guns, and in 18 inches was just under 2400 fps, and terminals were extremely good, better than most any conventional far heavier. I must play with this bullet some in 458 Lott for some of you guys, since I won't ever be taking a lott to the field again I have just been dragging my feet on that.

Right behind the 250 #13 HP I did a 225 #13 HP in .416, and it too is performing far more than its weight might suggest............. I have a friend with 416 B&M running the 225 at over 2900 fps as well and will be using it on brown bear on Kodiak in September......

As to the accuracy of light .458s..... I can't imagine there being issues there, I have been shooting 458s for over 20 years, and it is common to have 3 rounds in a hole with most any good conventional light bullet, and not uncommon at all to shoot 1 inch or less groups at 100 yards, I don't know what more you would want????

Michael

I haven't been keeping up with all the developmental processes. I did "like" CEB's Facebook page and saw they were testing a new bullet for the 458Socom. It happened to be a 250gr.


If we can have a 250gr .458/.457.......Can we have a 450gr .620?

Couldn't resist. Sorry.

I have not seen the facebook page so I don't know.....????? That little 250 is an amazing little bullet and like I said, I think its going to out perform its weight by leaps and bounds... We will find out!

Now, a 450 .620 is kinda heavy... Maybe a 400 will do? All you have to do is call Dan and have them made? LOL..... I would, but I don't have a .620, or we would have already had them by the 1000s.....
HEH...

A low recoiling-fast moving 400+- .620 does sound like fun Maybe try it on a big pig. I bet I could even un-screw the beer can from the front of my 600's

That 250 .458 Safari Raptor would be great in single shots for the 45-70 at say 2,350 FPS for hogs to groundhogs. Seems to group well in the 458 SOCOM. Those bullets will be good to 4k fps in a big 458 like the Lott or Wby.

HEH.... This is going to screw you up Drew.... Spoke with Ken this morning at CEB... They just finished a bunch of .620s in aluminum. Same bullet as the 900 gr BBW#13 Solid.. .Only Aluminum, weighs in at 280 grs. A fellow is running them at 3500 fps in 600 Nitro. HEH HEH..... Don't know the exact story, but I heard something to the effect that he is shooting steel plates, and the bullet vaporizes into a big white cloud...........

I have some news on the .458 250 #13 NonCon HP... Tested yesterday in Ballistic Gel at 100 yards in 458 Socom. Starting at 2100 fps, it was down to 1721 fps at 100 yards.. It did NOT SHEAR, tip blew, and it became a solid and gave 100% straight line penetration through the gel block, and lost in the berm. No photography or video available on that.

They are making a run this week and having slits cut in the nose profile to get LVSP down to lower velocity, 1300 or so. This should be interesting, they are going to test again, and I have some on the way that I will test here as well.

Seems that at 2100 fps in the Socom, this should make a hell of a bullet for that cartridge/rifle, especially if you can get LVSP down some.

I was shooting my 458 B&M today, 250 #13 NoNCon tipped, lower velocity at 2800 fps. If I do my part its all in a hole at 50 yards. Trapper was shooting the Socom, and getting 3/4 " groups at 100 yds yesterday. Nothing wrong with these bullets and accuracy........

Michael

And everyone thought I was crazy for pushing aluminum

I think adding some weight say 300 grains would be preferable to adding slits for lower shear velocity performance.

Nothing has changed my mind about you being crazy?

LOL...................

HEH.....

Boomy.... Smoking again.. Already have a 295... That should be close enough to work as 300???

Problem is, with a case as small as the 458 Socom, you can't get the velocity up, it would be starting at 1800 or so... 295 is much longer.......

250 is perfect, slits or cuts won't hurt the bullet at all, even at much higher velocity.....

I had the 295.... I did the 250, there was a reason for that.................

M

Guilty lol
Never liked my sanity anyway.
Yup forgot about the 295. Slits it is!
Maybe copper for a bit more weight and possible lower sheer?
As a high BC solid with a smaller cavity that is a cool niche. Engine block hammer.

I'm taking some 250gr tipped NonCons with my .458B&M to Namibia in 8 days. Testing them for Michael and myself. Hope to use them on some PG after the Eles are down. Michael can provide load and velocity info. Will report after I return.
