I love mine as well. I had been shooting a CVA buckhorn for the last 2 years. It did the job, but was not my favorite gun.
The pulled the Impact out of the box, cleaned the mfg oils out and the first shot went right through the 10-ring. Group opened up to 3 inches, but I haven't worked up loads yet.
I was shooting Hornady SST's (250gr) with 100gr Pyrodex pellets. This close to the season I won't bother working up other loads, but plan on 777/Pyrodex, with SST/FPB/Barnes/and possibly PowerBelt come spring.
