I decided to practice a bit yesterday shooting first at my metal swinging targets and later at a target. I was on my back porch making the targets about 25 yards away. I was surprised when I was missing the biggest swinging target which is 2 inches in diameter. I sat down on a bucket and used a bipod rest which is not attached to the gun and was still missing. I found I had to aim high and then I consistently hit. So I shot at a target and the gun was shooting quite low. So I resighted from the bucket and sticks and then tried that offhand using a porch column for support. The supported off hand hit at the same point as the bucket and sticks.
Today I tried again from a bipod attached to the gun from a bench, again at 25 yards. I hit high by about 5/8 inch with two shots. Then I tried a front rest instead of the bipod and I was back impacting like I did from the bucket and sticks yesterday. I might need to give it a couple clicks right but it is now sighted in for hunting. It really was not before.
I attach the bipod on my P35s using a printed piece that slips over the air tube and is clamped in position when you tighten the clamp of the bipod. I modified the adapter slightly by epoxying a couple shims of toothpicks to minimize cant adjustment of the bipod. So now the adapter touches the shroud of the rifle. It does not push hard on the shroud but it is apparently transmitting hard enough to shift POI a bit. The shroud is supported by the air stripper which has an O-ring to link it to the shroud. So there is a load path.
I was surprised. Maybe I need to take my toothpick shims off and try it that way. But what I really needed to do was check my zero at a more field typical support than my benchrest. I've hunted with the gun this way a couple times but the squirrels were hiding so I've taken no shots at game this way.
The two high shots on the attached picture are with the attached bipod. The three lower ones are with the gun on a unattached front rest.
