[QUOTE="johnnyk, post: 167238, member: 307"] I had the first generation Sendero in 7 Mag and got between 1500-2000 rds through the barrel before I noticied anything funny. Accuracy was still sub-.5" when I traded it for the 700P (same caliber) that I have now. Accuracy was great, most of the time, but it started "throwing" a shot every now and then. I could have lived with that at the range but not on a animal. Seemed like the barrel started loosing compression. If that's possible! Over time, velocity started dropping, even when known loads were used. The first 12-14" of the barrel were really rough and it became increasingly harder to clean. I assumed it was heat cracks. Tried JB Bore products but didn't help any that I saw. Through all that it still shot better than some of the newer rifles I was shooting/sighting in/reloading for at the time. What powder/primer/brass are you using with that 168gr Berger? Haven't found anything other that the 140gr TSX that mine likes so far. I really had hopes of finding an accurate load with a heavier match bullet for LR targets/an-e-mules. [/QUOTE]
