I thought a bad scale was the problem but I guess not. Today I still could not get consistency with once fired, neck sized brass, 57.5 Retumbo set .075 off the lans. 2 shots 1/2" apart one flyer 1-1/2 away. I am wondering if my barrel is copper fouled. This is why. I am about 100 shots in and I used hopped #9 to clean every 3 shots for the first 40 rounds then every 10 since. I was told this was not a strong enough copper remover for breakin. Could this be?? Need some help here.
In my experience Hoppes is not an effective copper cleaner, particularly with the rough bore that the Savage has. I would go with a copper solvent like Boretech CU+2. With the muzzle break on the Savage it's hard to see in the bore to check copper fouling. With the Boretech you can tell that the copper is gone when the patches come out white. You will likely have to re-do your break in if the copper was built up in the bore. The way you describe your groups, this may not be your problem. Are the flyers consistent, meaning that they occur on the the first shot, second, or third. Or are they random? An inch and a half off, after a half inch pair tends to be caused by bedding, mounts, loose brake. I would check the bedding as the Savage is sensitive to torque settings, 35-40#. Make sure the screws aren't too tight and that the barrel is making no contact with the stock cannel, particularly the end of the stock forearm. I had random flyers with my Savage 338 FCP. Turned out to be a bedding issue caused by too much torque on rear bedding screw. The design of the Savage bedding system, in my view, is very finicky.
