Has anyone had a good experience with any of these?
Edit: All of this is for .177
I've been testing some in my guns and have yet to find any that reliably compare to lead.

Using my Steyr and Mk4 the results are appalling with only one exception; H&N FTT Green have both outperformed lead on one test and given average results on another.

I've tried these bench rested at 15M in calm conditions

Tested so far:
H&N FTT Green - Mixed results. Sample tube shot a single hole group but the tin i bought after that gave 1/2"
Skenco Golden Rod - 5"+(Mk4 Only, too long for Steyr)
Skenco Blue Arrow - 4"+
Coal PSP - 3" ish - (I think these are also sold as Skenco now)
Proton Zinc - Too few hit the target to get a grouping

I've picked up some RWS Hyperdome too but not had a chance to test.

I don't NEED lead free, I just like exploring whats out there. Would be interested to know if anyone has positive experiences with the leadfree & composite pellets.
