>>All the vom Hofe Super Express cartridges are overrated paper tigers. Nobody ever measured the advertized velocities when factory loads were shot from real rifles over real chronographs. Apparently old Ernst – August vom Hofe shot his loads from absurdly long barrels over a typewriter to achieve the velocities he published. Remember, this was in the 1930s when nobody outside ammo factories and proofhouses had worthwhile equipment. At the same time American wildcatters too claimed wildly exaggerated velocities for their creations.
The advertized velocity of the 5.6x61 with the 77 gr bullet was 3700 fps. Factory loads rarely exceeded 3300 fps, more than 10 % less. The top velocities within max presssure listed by German handloading books are:
RWS: 70 gr at 3470 fps ( 52 gr R904)
DEVA: 70 gr at 3543 fps (41.5 gr IMR 4831), 77 gr at 3510 fps (61 gr H870 or 53.2 gr IMR 4831)<<

Most interesting comments by Axel E. on the Rimless version??? where he points to the possibility that only upper rung ammo factories were the only ones with Chronys and maybe even dial calipers??? Not sure what shooting over a typewrite has to do w/ the price of Strawberries in China, but I might shoot over an old Laptop to see the advantages??
