Thanks for the comparisons info. I went back out today and repeated my results with my 777 and the Sidekick. I also took my lady's Triumph and tried the American Pioneer in it. I got great groups with APP in the Triumph with the same Shockwaves and even Powerbelts. It seems that gun (The Triumph) shoots everything very nicely, which leads me to believe it may be the way the breach plug nests the 209 primer. My Sidekick has the plastic primer holders and may be less efficient in transferring the spark.

To answer Cayugad's questions, no I don't break up the powder pellets I just make sure they are seated prior to seating the projectile.

I would try BH209 ifI could find it locally but from the research I have done I do not think it will work very well in the Sidekick due to the type of breach plug/ Primer Holderit has. I am looking into a custom breach plug to hold the 209 primers like the TC has but have not found one yet. I really don't want to mess with the 25 acp cartriges and primers at this point. So I guess I will just stick with the 777 and swab. That's fine with me becauseI really place accuracy much higher than swabbing.
