I am confused as usual

[deadon]

I just left the Hornady site. They do not list a 45 cal 300 gr .458 XTP. Is the 300 gr .458 HP What everyone is shooting out of the 50 cal ml? also I read here somewhere about single and double canalur. Does the double replace the single or do we have 2 options? I have 12 of the single But do not want to shoot and love them if they are no longer available. Help please

I believe the XTP 's are the pistol bullets and they are .452 dia. they are available. in either the reg. or mag version, the mag having 2 canular rings at least the 300 grainers do.
The .458 dia bullets are used with much success also, don't know about the hornadys but the remington 300 JHP .458's are deadly both in accuracy and terminal performance.

hey bud, Mags have one cannuler, the regulars have two.

The .458's aren't the XTP, just listed as their regular rifle bullets.

I do belive onecard Chuck talked to Hornady, and the new 300gr .458's were two cannuler.

There have been many posts on this deadon.The XTP is .452 I believe. The .458 300 gr HP Hornada is #4500, and is not the XTP, but is supposedly a tougher rifle bullet, instead of the pistol bullet. According to most, .458 cal bullets shoot better out of the Savage than the .452. .458 Hornaday usually takes the orange MMP sabot (tighter barrel) or the black crush rib (looser barrel).

The newer .458 300gr JHPs do have two cannelures, the older ones do not. As far as being a tougher bullet then a XTP, sorry, the .458s have a very thin jacket compared even to a regular XTP which helps make them maybe more accurate.

All good informative posts here.

Al is correct I got on the phone with Hornady and all new runs of the .458 300 grn HP's called the 4500 are going to be double cannelure.

Rossman is also correct it should be a very accurate bullet( I am still working with it) due to the thinner jacket but not the toughest of the bunch. You can see this in the cutups post by Al, which by the way Al great job.

Hope this helps,

I'm usually confused with a capital K. ;-)

Does anyone know if the double cannelure shoot any different than the single?

[onecardchuck]

deadon,
My guess would be the double cannelure would be slightly more accurate than the single cannelure, because the double cannelure should weaken the jacket a bit more than the single cannelure. Therefore allowing it to objurate a little better. I am currently working with the double cannelure ones, but I do not have any of the single cannelure ones to compare side by side. Another thing is the way ammo and bullets are flyuing off the shelf I don't know if you can even get more of the single cannelure ones.

However, if you want to satisfy your curiosity or just test out the double cannelure ones I would be glad to send you some for comparison or just to try at your next range session.

Let me know,

Instead of the cannelures being up on the bullet the .458 300gr #4500 has one cannelure in the normal place and the other almost at the heel/base. I have no idea why unless it is to improve jacket retention and Hornady can call it a "Interlock". The number of traditional, classic or original bullets in Hornady's line up is dwindling fast much as it is with Barnes. Barnes is down to like 10 bullets in the original line that Fred started with.

There only a few of XTPs that have double cannelures, the .452 300gr and IIRC the .429 300gr and the .357 180gr. Basically big bullets and the extra cannelure allows more setback for the crimp when used in other shells. Like if you used the .429 300gr in a 44 Special you need it shorter then when loaded in a 44 Mag
