Hello all, I have over 1,000 rounds in my HS Precision HTR in 308 and today I noticed with my Hornady Overall Length Gauge that the bullet appears to be .020 longer in order to engage the lands than when new. Throat erosion of .020 basically. It is only six months old and again 1,000 rounds shot through. I have ridden this thing hard in only six months but my question is, is this rate of erosion normal? It seems to be retaining its accuracy but will I need to ditch the barrel soon? Ive heard some say these 308 barrels can go for 10,000 rounds. I am beginning to doubt that. At least while retaining the 1/2 moa accuracy it currently has. Thoughts?
