[QUOTE="remingtonman_25_06, post: 150350, member: 1403"] Welcome to the wonderful world of ballistics, ha ha. Yah I've had pretty much the same thing happen from my 7 RM and 140g NBT's. I was 3-4 MOA low at 800 yards. I had it crono'ed at 3250fps, entered .485 BC, and came up with however many MOA"s at 800. Well I was really low. I figured 1 of 3 things from help on this board. Either my MV was not 3250fps as the crony stated, (probly closer to 3100) the BC was not .485, actually closer to .350, or my scope was not giving true 1/4" MOA clicks. Well I worked everything out, backwards, yadda yadda, I just figure that you write down how many actual clicks it takes and shoot and be happy. Otherwise you'll find yourself frustrated and trying to figure things out that really cant be explained. Computer ballistics are only a guideline, I now know that for sure. [/QUOTE]
