The bullet they are using is not their standard ELD match or X bullet. The new bullets are longer than a conventional bullet of the same weight. They do this by using a different type of lead, and by moving the lead inside the copper sheathing towards the back of the bullet on the initial muzzle velocity using the same weight bullet, a 22–250 will have a higher velocity; but by the time you get to 250-300 yards it has shed that velocity and the newer bullets will maintain that velocity, and have less wind drift. Additionally, you cannot shoot these new bullets and traditional twist rates for example, my 22 to 50 AI has a 1:9 twist rate. it does great with 55 up to 69 grain bullets but I could not put the new ELDVT bullet in that twist rate , and expect top stability, as it requires a one and 7 1/2 or faster.
Likewise, you cannot put these bullets in a 223 AR15 because it will not fit in the magazine length.
it's hard to argue with the success of Hornady in the last 10 years. The 6.5 Creedmoor is a better all-around cartridge design and performer compared to the 260 Remington the 6.5 PRC is probably on par with the 6.5 x 284 but it is an a short action, so that to some is an advantage. The new 300 PRC and 7 mm PRC surpass the 300WINMAG and 7 mm Remington mag when using traditional twist rates… not by much however. The 6 mm arc is a fantastic light deer antelope coyote round, and it will only be better with these new longer lighter bullets. The 22 arc is not just a necked down 6 mm arc …they did have to lengthen it slightly.
