Chuck,
This is a great story and wonderful ending to your hard and diligent work. Congrats! To clarify your statement "I recently got one of the new STX Superior Liners – (.30/700mm *FX Hybrid Slug Liner) ", this is to mean you have the newer twist rate of 1:26 specifically for the .30 ? I am so happy to hear your comments on the Athlon G2 Helos 2-12, I have one on order specifically for my .30 MK3 Sniper.
Patrick
