.458 Hornady bullets.

[Axis II]

Just incase anyone is wondering I got some good info back from Hornady regarding the velocity and performance of these bullets.

I had issues on two whitetail deer where the bullet didnt exit or didnt cause the kind of damage one would expect from a 300gr Hornady HP. I was only pushing them at 1500-1600fps per the book. It got me wondering so I emailed Hornady last week and asked what the minimum muzzle velocity should be for their .458 300gr XTP? Hornady responded within a day and stated the minimum velocity for the bullet to perform as expected would be 1600fps but they recommend more velocity to obtain consistent performance. I heard rumors about .430 240gr XTP not working well on deer so last year I worked up a load to near max of IMR 4227, mag primer and 240gr XTP. My buddy shot a nice size whitetail a hair over 50yards with it and the exit hole was about 2-3'' in diameter and sent the heart into tiny pieces. He claims to have seen the impact because it did hit bone but it drilled all the way through and out the other side. I guess these Hornady bullets need to be pushed fast to do good.

What are you loading them for, .45-70 or 458 SoCom.

Did you Chrony the loads?

Seems slow for a 300gr. What barrel length?

24” that was per my specs to hornady. If using the guide gun I’d maybe go faster than 1600fps

So, it made a 45 caliber hole in, and out, at an impact speed lower than recommended, and it failed?

No, I get what you’re saying. But, I don’t think I want a three inch hole going out.
We’re these the XTP Mags? They are made quite a bit sturdier then the XTP. I forget which weight they make both in. The Bushmaster is at the threshold between the two and I waffled a bit but went with Speer because they were cheaper!
But, I was thinking at the time, if it doesn’t open because it isn’t going fast enough, at least it’s a 45. It won’t need to.

Normal 300gr HP but I do think they are bonded.
