I shot my 209x50 all season last year using 120gr TripleSeven loose powder under a 245gr Powerbelt aerotip bullet. What a great combo!
I got consistent groups under 1.7 inches and every cold shot (first of the day) went within one inch of point-of-aim on a 100-yard target -that was a 1-inch dot pasted exactly 3.5 inches above the bullseye).
Using 110 gr loose T7 I got under 2" groups on the same setup.
Now they have brought out the pellets, and I either have to settle for two pellets or the full boat of 150 grains, and I realy don't see the point. I don't need a magnum load for whitetails, and the recoil is prohibitive for my 1xx-pounds and a pinned shoulder.
Dontcha wish TripleSeven came in 30- or 60 gr pellets???
