That was the general idea. Dont forget that at the time BSA Pylarm pellets were identical to Eley Wasp made in Witton Birmingham and supplied to BSA to rebrand. They were a large stiff pellet although power levels were checked with BSA Huntsman which were not available to the public. It was made exclusively for BSA as a pointed pellet and unusually was quite accurate. JB told the fanpage that during development he used several one gallon paint tins full of them. It worked well and gave good power in the springers too even the magazine fed ones despite weighing 16.3 grains.
