You're top of the list to send the action back to when I figure out what I'm doing.Have not done a 24" YET!!
I have done a pile of them in 26" 9.4 tw and they rip
With my 338 reaper (338 lapua improved) design it will run respectively mid 2900's fps w/300 gr bullets and 225 gr stuff will run 3400fps
I would love to do one but until my 26 gives up the ghost it wont be getting a new barrel anytime soon!
