Just bought a tin of these to try out in my BSA Spitfire (apparently same barrel as many othe BSA rifles). 1) They are very hard to push flush into the barrel 2) In the sun through the scope at 9x I could see the pellet "corkscrewing" towards the target - which incidentally it did not hit. The hollow point seems to make these unstable in flight - for my gun at least. They're not even useful for plinking - I'll throw them away.
