Pretty much... Sounds like one bad bastage, huh?
Oh yea! That thing will be close to a .300 RUM but is so unique, very cool cartridge. Looks to be a real winner!gun)

Wish I could take claim, but you can thank ole P.O. for that stroke of genious. Can't wait to get it built.
I bet it's gonna sling 210's like a house of fire...
Haha Ackley had it right with most of his stuff back in the day. That .300 Ackley would most likely launch those 210s close to 3100fps depending on barrel length. Very impressive!

It'll be a 26" 1:10 twist Sendero SF .300 Wby barrel that's been rechambered to .300 Ackley.
Yea you will definitely be looking around 3050ish with those 210s! That is some serious horsepower!
