Winchester Model 70 long range rifle.
A few years back I glommed a 1965 Winchester M70 target model with a Hart barrel in 308. It came with a set of RPA "Trakker" sights and Earle scope mounting blocks. I got busy and kinda left the rifle in the back of the closet. Anyway, I've given up on trying to use the external adjustable scope mounts and went ahead and put a one-piece scope base on it. I also mouned an old Bausch and Lomb 6-24 x 40 scope that I had lying around.
I took it to the range for a test firing. After getting it on paper with some cheap .308 ammo, I switched to 168 FGMM at 100 yards
Moved back to 200 yards and switched to 175 gr FGMM
Moved the target to 300 yards
Finally tried some handloads at 300 yards...the Winchester liked 41.7 grs of 4064 best. (I was going to try a three shot group, but threw the third shot out at about 11 o'clock, so I turned it into a 5 shot group). I noticed that the point of impact shifted to the right when I switched to my reloads.
