Update: New bases
First off, I want to thank all of you again for steering me in the right direction with respect to the bases on this gun. I got out to shoot it today, and I had some interesting results.
The last time I shot from 115 yards, but the position was kind of uncomfortable, as it put me on a slight decline. The only way to fix this was to pull back to 125 yards, where there was a little plateau to shoot from.
The wind was nil last time, but this time there was a 4-8 mph wind.
The last time, the Hornady 30g V-Max ammo grouped a little better than the Remington 33g Accutip-V. With the new bases, that is reversed. Not only did the Remington seem to buck the wind better, but it grouped better too.
I won't bother posting pictures of the 125 yard shooting, as they are nothing special. In truth, I did learn that my absolute limit with this gun is around 125. I would probably feel more comfortable self imposing a 100 yard limit, just to be sure.
Anyway, seeing that my groups were not fantastic at 125, I moved forward to 115 to shoot a couple of groups at the end of the day. This is what it looked like:
Hornady 30g V-Max
It's a crappy group, at just under three inches. Fortunately, the Remington ammo made up for it:
That one is 1 1/8 inches, and it could have been better. I called the leftmost one - it was definitely my fault. Not sure about the lowest one.
At any rate, I will be keeping this gun.
One other thing, if I thought things were tight with the low rings before, they are certainly tighter now. The bases are a bit shorter than the old ones. Fortunately I can still pull the bolt out of the gun, so all is well.
