[QUOTE="Guest, post: 85259"] Had some interesting results these past 2 weeks. It basically solidified my feelings that target knobs just don't work or won't work in all conditions. a few of us had to re-evaluate our dope on some of the rifles. Even my beloved 7wsm was a 1/2" low at 100 yards. now that doesn't seem all that much until you go to 500 yards. This could be an easy miss. After some of us missed easy shots. We set up a steel gong and re-evaluated our dopes. After that it was back to business as usuall. As best we could tell the changes were from Alt. and Temp. We had a cold front move through and the temps dipped into the upper 20's and low 30's . Most of us had dope for 60*-70* + This isn't a slam on the guys who make the BDC knobs. Just some real word data that contradicts what the computers and ballistics programs might say. Truth of the matter is. I wouldn't trust the knobs or my drop charts until I confirm the data at the place and alt. I am hunting! take it FWIW [/QUOTE]
