Wll I guess I am going against the grain here...
I shoot 3 pyro pellets with a 250gr "Dead Center" sabot and shoot 1 hole groups out of my T/C Encore.
I really like the fact that the pellets have uniform compression, which lends itself to more uniform grroups. Try dumping an even 90gr of powder down a bbl on a windy day; maybe you'll get 85gr,87gr, who knows? Then try doing it on a follow up shot when you're adreneline is pumping. You may end up with even less powder than that down the tube.
Sure, there are lots of folks that can do it perfect every time, but I think this is more the exception than the rule.
I also like the simplicity that pellets offer, no measure to carry, no funnel to deal with, just 3 pellets and a bullet.
This year I am even going to look at that new offering by Hornady which allows the pellets to be snapped on the the end of the sabot...even less fumbling around!
Often time getting accuracy with 3 pellets means trying different bullet/sabot combinations to see what works. Since you do not have the adjustment in the powder you have to make adjustments with your bullet weight and sabot.
