It will push the bullet development in .257 and for that it is worth it.
I don't shoot PRS/NRL or F-Class currently but I will again. I think it would be a great cartridge for all 3 disciplines with the new Hornady bullets.
This and the new 22 Creedmoor really for me spur a lot of interest in light kicking rifles that punch above their weight on smallish to medium game and predators.
I am hunting this year with a 243 for the first time in 20 years. The bullet development pushed by the precision rifle sports has given the smaller calibers bullet development interest that I never thought would be possible.
I am sitting on over 1000 rounds of RWS once fired 8x57 brass. I had planned to build a 6mm-Ackx57 when I get back to America. Because of all the bullet development on these smaller calibers and the new bullets for the 224, I am also going to build a 224-Ackx57. I have a 5,6x57 RWS, but because of its stupid neck thickness it's sucks to work with.
At some point I want to work with a 25-6.5 PRC, or 25-06 Ackley with a 1 in 8 twist.
I appreciate Hornady being the engineering king that it is. No other bullet company compares. RWS, Lapua and Norma may build better brass, but their ballistics engineers aren't producing what Hornady is.
Federal, Barnes, Nosler, Remington, Winchester aren't even showing up to the table.
I also appreciate how much Hornady pushes their marketing and engineering teams for customer engagement. I listen to a lot of podcast on shooting and hunting, and the content driven by Hornady is tops.
