[QUOTE="yorke-1, post: 1678503, member: 11960"] I actually had the same thing happen with the 6.5 Badger and US869. I had a go to load that was giving 3430 fps with the 160gr Matrix and had been for almost 200 rounds. I loaded up another batch of 50 with all the same components and ended up with a sticky bolt. I had to back it down 1.0gr to get back to the old velocity. Some of these overbore rounds are a never ending project! I kind of consider it a success just because it easily hit the performance numbers I was looking for. I might come back to it later and try again just because I have a PILE of different 270 bullets sitting on my shelf now. LOL I got a chance yesterday to swing by a local gun smith and cash in some lathe time that he owed me so that I could finish up a 7mm SAUM barrel that I've been stalling on for a while. I just had to set it back a couple threads and re-thread and chamber the barrel because the original chamber had a bad chip ring in it. I took it out to test fire today and it did well enough that I won't have any trouble forgetting all about the 270 project. This was with a load I just threw together to get the scope zeroed (168gr Berger VLD and H4350). This wasn't a one off group either, the largest one I got was .380" on centers and that was with the Magneto hanging off the end. [IMG]https://i.imgur.com/5HEOWUC.jpg?1[/IMG] [/QUOTE]
