300HAMR BARREL TWIST

[bobcat93]

It honestly doesn't matter ive seen what this cartridge can do on Willson Combat and Banana Ballistics videos..
Its nasty !
Being on a strict gun budget of (no more) one more isnt gonna hurt anyone
brass, dies powder its all over..when did this happen? Factory ammo is available.
I feel an important need for semi auto 30. As i dont have anything like that
Enough im willing to take a new Kreiger varmatch barrel off
Whats that say-n
Hell i could probably sell the barrel and completely fund this endeavor.
Not sure if i could part with it.
Those barrels take so looooong to get and worth the exercise in patient's

Unfortunately, neither the 223 or 221 Fireball sizing dies will help (case lengths, shoulder length/angle are different). The neck & shoulder of 300BO and 300HAM’R are almost identical with minor difference in length of neck (.266” 300BO / .234” 300HAM’R). The primary difference is the length of their case bodies (1.071” 300BO / 1.341” 300HAM’R)

That lineup looks even better with a .222 included

You'll enjoy the cartridge. Keep it simple and buy Starline brass, set of dies and maybe a Redding 300BO Tapered Crimp Die, CFEBlack powder, CCI 450 primers, and whichever bullet that fits within your magazine and rifle's chamber.

Oso, Don't forget the pics of the 222 rem mag and 6x45.
