You've got it backwards: The moly coating on Supreme Balistic Silvertips may reduce COPPER fouling a LITTLE, but in it's place it leaves a LOT of MOLY fouling...it cleans out pretty easily though.

Personally, 1.25" groups at 100yrds is nothing to complain about from a light weight rifle. I'd at least try them out, but you're not getting hurt by your groups right now.

In most of my rifles, the BST's shoot INCREDIBLY well, MUCH better than any of the Super-X line...really, I think it's the Supreme line that they like, as the Supreme Power Point plus's are pretty accurate from my guns as well.
