G'day everyone, Can someone tell me where they seat these bullets in their 458WM. At the cannulure closest to the base or the one at the front of the bullet? And what velocity do you load these up for pigs, big and small? Cheers, Mark. | ||

The 300HP .458 I bought only have one cannulure. Due to these bullets being so short I turned my seating die all the way down. Velocity was around 2400fps. | |||

You figure out where the rifling starts in your chamber. Then you set the bullet off the rifling. I'd expect in a .458 WM, you'd seat the bullet longer rather than shorter insofar as most loads for this caliber use a longer, heavier bullet. The short OAL is likely intended for 45/70 Govt. | |||

I understand to seat bullets to just miss the rifling or to fit mag box but these bullets have, as I stated, two cannulure grooves. The one which would seat the bullets out the furthermost will only have about 3mm (1/8") of the bullet in the case mouth..... Cheers, Mark. | |||

The only Hornady .458 bullet I know of that has 2 crimping grooves is the 325 gr lever evolution bullet. I would seat and crimp it in the foward most crimp groove, ie closest to the tip of the bullet. DOUBLE RIFLE SHOOTERS SOCIETY | |||

Mark we used the 300gr hornady hp in the 450 marlin... at 2150 or so, the bullet failed, catastrophically .. some might say it over expanded or some other bs, the truth is the bullet detonated ... fragments, nil weight retension.. these had a single groove ... and in no event could that bullet have been loaded to touching the grooves in a 458winmag.. but that's NOT important in a bigbore .. seriously.... iirc, hornady recommends NOT exceeding their max vels in the 458winmang with these bullets opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

I tried these in my .458 Lott, seated in the cannulure and loaded to 2760 fps....they shot straight without much recoil but were worthless for anything but shooting snakes in a stock tank...they EXPLODED on contact with just about anything...they would not completely penetrate a one gallon paint can filled with water, would just turn the can into a flat piece of tin with an entrance hole, but the lid and bottom would fly waaaay up into the air.

Sounds like the PERFECT projectile for use against dangerous mellons, pumpkins and charging water buckets! My nephews will ahve a blast with these in my 450NE!
