I was wondering very new to the fx impact, and was wondering if the 34gr pellet, and the 34gr slug would shoot equally at same tune, I'm shooting 25 cal.
different speeds meaning different power strokes. that will be your homework to learn each. I would suggest master the pellets first and next year you can go shoot slugs if still that is your interest.
Thanks to everyone, very helpful, had opportunity to shoot with someone knowledgable with this airgun a little windy but off to a great start, omitting slugs for now, tuned for 34gr heavies, then 25gr, pleased with results.
