Ron should have been saying it was equivalent in case capacity to the .35 Whelen IMP.

Mine ran 2,519fps with 285gr. Speer.(4016fpe or there abouts)
It also did 2,670fps with 270's, but that Speer bullet is about useless.
These were using BLC2 only. I have a feeling it would have produced the same ballistics with H4895 powder, just as my .375/06IMP did.
