Tried Hawk Bullets?

[Murmur]

Yes it's good to have you on board Richard! All my whisper shooting to date had been with 240gr Matchkings at subsonic speeds so would love to get my hands on some similar weight bullets that EXPAND at that speed. That would simply be the ducks nuts and would get an order of 500 bullets straight away.
Thanks for taking up the challenge PMC - I will eagerly await results of your trials. Its good to see someone with your experience and back to basics testing to try these things out.
