I hadn't checked a .20 Practical A/R rifle on paper in several years of fairly heavy round count varmint shooting on it. Before going to the range, I bore-scoped it and the throat was just plain gone. Smooth rifling for a few inches. Yikes! So went to range to see what it was doing on paper, as I had already loaded up another 1,500 rounds for the upcoming spring shooting. I was thinking that was not such a great idea. I use two bullets, mainly - the 32 V-Max and 40 V-Max in that rig. The 32 V-Max shot .318" and the 40 V-Max .285" 5-shot groups @ 100 yards in 5-10 MPH wind conditions. I find it fascinating that the bore and throat could change so drastically and the barrel shoots as good as it did 6,000 rounds back. I never altered the bullet seating depth or changed the powder charge through three lots of powder (Accurate LT32). It just keeps ticking.... Makes me wonder how many of you out there have rifles that keep shooting - and how many rounds you were able to get on them before they took a dive.
