Mitch,
I have had no experience with Barnes bullets. i don't know that much about them. I have had some
excellent results with a number of different Sierra bulltes (SPTs, Blitzkings, and Blitzs) out of the Handis though. You know how it goes- once you find something you like, you tend to stick with what you know.
FYI- TNTs in a 243 is like serving your varmint some nitro also!! Crows=POOF, G-HOGs= SPLAT, feral cats= EXPLOSION, and Coons=INTESTINAL STREAMERS!!!
If a person wants to turn there .243 into a mass carnage weapon, get some TNTs.
