So I was mistaken. The bullets I have are 80’s.
They’re loooooooong. Probably not a good fit for this rig.
they will work just fine.... it can still push 80s from a bolt action in the 2700 to 2800 fps MV
without being over SAAMI specs...and they will stabilize just fine with a one in 9 twist.
Make a dummy round, and see how far into the case body you have to seat it to clear the throat limitation of your rreceiver...
i have a single shot Savage BVSS in 223 with a one in 9.... its a very accurate target rifle with those longer bullets...
