The BSF 80 was a rifle ahead of it's time -- a bold claim !

But it used the proven action of the 55/60/70 series coupled with a new design of stock and a barrel weight.

These things and hamsters were being used by experimenters at the time in the early days of FT and HFT (mid 1980's)

If you look at the Venom Vantage stocks that followed the inspiration was there IMHO . (Venom had collaborated with Herr Gayer of BSF who rescued the company prior to 1984 demise and it's purchase by H Weihrauch)

Most FT / HFT stocks since then have more depth in front of the trigger guard / or a hamster to this day, compared with previous sporter stocks .

The R&D budget therefore must have been small despite trying to update proven designs to live with the HW80 which had swept all before it ( Not least because of the power it had which blew all others out of the park)

Before that only BSF's could well exceed 12 ft /Lbs with a tune and export spring.

FWB sports would just make 13 ftlb in .22 with MAG Hornets ( 5.5mm Wasps )
