[QUOTE="Fiftydriver, post: 1634310, member: 10"] Steve and Brian basically met my dreams with this bullet design. It was a design to work in my chamber and throat specs so if they were designing a bullet for the market, I am sure there would be differences so I must say up front that they went above and beyond with this project and the results were amazing. Also, this bullet was designed specifically for this 458 Maximus which is not to say it will not work equally well in any other large 458 caliber rifle with appropriate twist rate. It WILL NOT work in a repeating rifle, it WILL NOT work in a rifle where you have to seat the bullet very deeply into the case capacity. This is a hybrid bullet design meaning that the front drive band is a few thou over bore diameter which means that the rifling WILL engrave the front drive band but not very deeply. Simply to provide the function of centering the projo in the bore and giving it some front end rotational stability. The body of the bullet is very reduced for no contact with the lands in any way. Then there is a relatively short rear drive band of full groove diameter for proper gas seal. Had the bullet been designed first then the rifle built after, I am sure there would have been some changes to this design but for the purpose of this rifle, its nearly perfect in my opinion. Give the advantages of a conventional projo being able to be seated to the lands for fine accuracy and instant bullet rotation as it starts down the bore. Also gives some of the advantages of a bore rider as its pretty slippery to push down the bore because of the limited contact with the bore. In my testing, with the 458 Maximus, the neck tension was PLENTY to securely hold these projos with no worries of bullets being moved out of alignment with the bore. However remember this is a SINGLE SHOT RIFLE and these bullets in the 458 were designed specifically for this purpose and use. [/QUOTE]
