After thinking it over we had just returned from a vacation trip and I had not done any shooting for two weeks. I normally shoot every other day or so with the air pistols. I shot the pistols in the order of HS, Sig, Ruger, 46M, FAS 604 and Crosman 2300S.
The scores improved the longer I shot and the 2300S was the last in the string. I was probably just recovering a bit from the two week lapse. I have noticed that as I have gotten older (68 now) that my shooting degrades rapidly without practice.
It was interesting though
