I think that unless you are shooting in the 95% or better category, that the pellets at 10m will really not make too much of a difference to your scores.

Even at longer ranges (25 yards) the low cost pellets such as the Geco's and Hobbies group surprisingly well.

You will get more benefit from shooting 4 tins of Geco's to one tin of premium match pellets, just think of how much more practice you can afford.
