I know its older but.
I have a TC Omega that I started shooting the 300 gr FPB / 100grs BH209, and the accuracy was OUTSTANDING...Took a 110# doe qtr on, thru shoulder bone (destoryed it) and passed on thru at about 30-40 yrds. Quarter size exit.
THEN I bought about 10 packs to be sure I had enough forEVER....Went to the range again after finding loose scope screws...and it was all over the place...figured it was the scope / mounts.....Nope. STILL haven't been able to get them right.
Will again try, but....WTH happened? I liked them ALOT !
