Hey up Andras,
As im a bit thick about these things and whilst were on about velocity with heavy pellets does shooting these pellets use more air?? As i have noticed you have to exchange your cylinder half way around a gp coarse.
If you switched to 8.4 grain pellets would you still have to do this?
