pok told me they were exactly the same in coils / thickness / steel spec as venoms hence why i used them.
i had a rapid mk 1 as well but each week i took the hw77 to shoot against steyrs / mk 2 rapids and a mfr and beat them everytime.......it was then we realised it was over the limit by a long way.
if i didnt know the power it produced with premiers ( crosman premiers in the cardboard box were the pellets of choice in them days ) i could have kept it below 12ftlb with other pellets but the law says any pellet etc.
i just think the die 4 box was perfect for the hw barrel......the rifle didnt have any delrin buttons on the piston just the plain one.....it did have delrin piston guide though as my mate worked with delrin at the time.
he comes on here sometimes as he will remember it as he tried it out in his back garden and couldnt believe how smooth and accurate it was....
i do miss it though even though i dont have any air rifles now apart from my colchester game keeper.
it had been cocked so many times the bluing was worn away from the lever lol
