200+ Grain Bullets in 1:10 Twist .30 cal

[WisBorn]

As we discuss the barrel twist and the physics around velocity and delivered RPM. The opening post mentioned a specific bullet design in a specific cartridge at a expected velocity.

So - I'm going to ask the obvious question! What barrel twist does Hornady recommend for the 212 ELD-X at the expected velocity of the 22" barrel? I would hope that rhe customer service at Hornady could provide that.

No velocity on the box, but id assume 1-10s plenty for most.

Round nose and short ogive bullets are not the equal of long ogive VLD type bullets. It’s pretty easy to add a quarter inch of length to a 30 cal bullet in this weight class, the longer of which obviously requires greater spin stabilization than the shorter.

Understood, but I doubt that automatically means every pointy .30 caliber bullet over 200 grs. is going to require a fast faster than 1-10".

The op asked specifically about a long ogive 212 ELD-x…

Pontificating about hundred year old round point bullets doesn’t aptly answer the question.

It's a discussion and no one is pontificating, so you can run along now. (Round point? Oxymoron much?)
