Anyone have problems with their Oehler 35P when it rains on the "skyscreens"? Mine seemed to have a disagreement between the main and proof MV of 30-90 fps the last time out that I never have seen before. I finally hooked my Oehler "43" up to another rail I have and got fine results in the rain, well, until the water droplets had to be wiped off the lenses here and there. The 35p started off working normal, 1,2 or 3 fps difference between proof and main MV, then it just went down hill from there. After carefully measuring the distance the screens were set apart, thinking one may have loosened and gotten moved from muzzle blast, I found all was perfect, tight, the whole 9 yards. No idea, but to check it again tomarrow while switching rails between the 35 and 43. Anyone made rain proof covers for em? Thanks for any input on this.
