Just did a little search and found a few different quoted BC's for the 10.3 - 0.023 being about the lowest over on the Yellow/Green forum - Chairgun quotes 0.031 which is quite a big difference.

Compare a 10.3 grain pellet with a BC of 0.023 against an 8.4 with a BC of 0.026 running at the same muzzle velocity and tell me which one has the better trajectory and takes less wind
