Speaking of cleaning barrels, yesterday I had a real experience. One of my rifles shooting a popular 6mm silhouette round was just not shooting as well as it could. So, I gave it a cleaning. Used Hoppes, followed by oil, followed by three dry patches. First noted, the barrel, despite have over 200 rounds through it, showed virtually zero carbon or soot or copper fouling. I thought that very strange. (Cleaned by 6.5CM next and it had the usual amount of fouling, some light carbon that came right out.
Here is the strange part. First shot, it smoked like a cast bullet gun shooting bullets lubed with an alox style lube. Lots of smoke. Second shot showed a fairly heavy bolt lift. Third shot on was normal. Accuracy seemed to be spot on at ranges under 400 yards, but with that load (Varget and a Berger bullet) never could connect with targets700 yards and beyond. Switched to my Sierra bullet load and managed hits on both 700 and 800 yard silhouettes. This rifle is somewhat of a problem child anyway. I am going to discuss it with the builder, that’s why I am not naming names or actual cartridges. It is a great place to do business, and I don’t want to down them in public.
Just so you will know, the 6.5 Creedmoor was spot on all day. And the 6mm load was well below maximum and has been shot in this rifle for approximately 500 rounds with no issues previously. (Including 60 of the rounds in that 100 round box).
All this all but makes me want to go back to 6.5 Creedmoor. I was in the process of converting everything to 6mm.
