I don't know the dimensions of the target rings, but it would appear to be sub-MOA minus that "flyer."
I think I'm approaching the point where I am the limiting factor. The little white paster marking the center of the target is bouncing around the reticle of the scope. It is cold and my teeth are chattering
Next string using 37.2 gr of Win 748. Chronograph went out to lunch on two of the five shots, so I only got velocities of 2617, 2690, and 2625 fps for an average of 2644. I think I will go to 37.5gr next since I'm not seeing any problems with the primer and I am closing in on the desired 2650 fps target velocity. I did get a clean target this time around.
Had a visitor show up to test out the rifle I rebarreled a few weeks ago. A mid 1970's Remington 700 BDL LA. Changed it to a 270Win using a 2000 era Remington hammer forged barrel converted to Remage barrel nut. Started spitting snow so time to call it quits for the day.
