Then use only RWS Hobby or Basic.

My only comment is I have found cheap pellets were NOT very CLEAN.

Agreed. Cheaper pellets (including RWS Hobby) have visible pieces of swarf that can fall down the transfer port in my rifle. They also jam under the loading probe.
If you have a FAS 604 it's not a problem

It's no biggie, put the pellets in a plastic strainer, wash them out, dry them and add a couple drops of oil. They come out spanking clean...

As we say in UK, I can't be arsed to wash pellets!!

As we say in the U.S., "Damn straight!"

As we say in NZ, "He taonga rongonui te aroha ki te tangata, and RWS Basics are pretty nice too."
