Hi, I've been lurking, reading, and learning for a long time. I've only posted a couple other times. Recently I began putting together a Savage 110 in .260 Rem. with a Pac-Nor 28" barrel Sendero contour. It has the Bell and Carlson Duramaxx stock and has not been bedded. My first couple trips out to the range were successful while also giving me some headaches. So here is my first headache: I was using factory ammo to break the barrel in because I was unable to find 260 brass and didn't wan't to start off by resizing. I was breaking the barrel in by shooting one shot and cleaning in it. It was grouping right around an inch. I was very happy with that. I did this for the first 12 shots. I then switched to shooting three and cleaning. The groups opened up dramatically, 3-4 inches. I was not frustrated at first, assuming that they were going to get better with break in, but after a total of 28 shots like this, the groups were still the same. Is this a problem that bedding would solve, or should I continue the break in. The shots were not in rapid succession. Also, I have read that a great benefit of a long action in short action caliber is the flexibility in seating depth. Knowing this, I wanted to try some 130 Berger VLDs. Does anybody have pet loads for these? I have about 6 lbs of IMR 4350 for other guns so if anybody has a pet load with this powder that would be great too.
