Got my .25 avenge x sighted in this afternoon. Just used a tune off this forum for 25.3's. Haven't fine tuned it yet so I'm sure it will tighten up some. I didn't set up my ProChrono today. I'll work on that tomorrow. That's at 35 yds. Not bad for not being fine tuned. I'm going to enjthis gun and dialing in my pert tune. Thanks for the info shared with me on this site.
