The HW35 was introduced in 1955. Today's Weihrauch catalogue lists HW35 velocities as 240 m/s @ .177 cal / 175 m/s @ .22 cal. That works out to close to 12 fpe in the bigger caliber.Were the early HW35's of the 50's already this powerful, or have they been "powered up" somewhere along the 65-year production?

Had an older 1982 version, with leather seal which shot much nicer than the modern ones, especially if choosing .177It was sublimely accurate using Hobby pellets but never got past 750 fps. Quite mid powered for such a big gun due to the swept volume being all wrong for making big power, even its massive cylinder suggested otherwise....but it did not bother me. At that time it was described in HWs literature as being a long range air rifle?...I presumed incorrectly because of its power, but a BSA Mercury I had...the later S version could hit 870 fps.However, in “long range”, i think they meant accuracy, as the gun out shot any BSA I owned.I always found the fore end grooves on it a real boon in the field...never understood why this superb feature was dropped in favour of the poor chequering on the more modern stocked 99/95 etc. with much plainer grain to the wood.....almost dull in comparison..Progress i suppose. In fact so wan is the woodwork on newer models, i wish i had kept it..
Good to know, Steve and Mick!So, Mick, when you say the 35's provide many power levels, incl. above the U.K. limit, do you mean that there are aftermarket kits that can get you there? It is news to me if Weihrauch offers over-12 fpe models.

It is news to me if Weihrauch offers over-12 fpe models.I had not heard of this myself, but no great argument. The way I understand it, the HW35 had a long 4mm TP which worked ok with the soft Cycle leather seal.It then went to Synthetic seals, which saw the gun turn nasty to shoot but pick up a bit in velocity.Finally, they reduced the TP to 3mm which made the Synthetic seal shoot more like its leather sealed former self.Never heard of them happily exceeding 12 though...The swept volume and TP length working against it a bit.

If there is info out there that discloses "How Too" extract 12 fpe, sure love to read it !
