[QUOTE="Perkules, post: 29541, member: 945"] Hello Stugotz, I played around with a program for a while, adjusting the velocity only. Velocity can often be the guesswork after all. I was able to duplicate your path quite well with the MV being 3450 and zeroed at 290 yds, everything else being equal. I would trust the BC -based trajectory with the shooting you have done rather than tweak the BC. Close enough to get an idea,I hope. 0 3450 3675 0,000 -1,82 25 3389 3546 0,021 -0,54 50 3330 3423 0,044 0,55 75 3272 3305 0,066 1,45 100 3214 3189 0,09 2,15 125 3158 3079 0,113 2,63 150 3103 2973 0,137 2,90 175 3049 2870 0,161 2,94 200 2995 2769 0,186 2,75 225 2943 2674 0,212 2,32 250 2892 2582 0,237 1,63 275 2841 2492 0,263 0,69 300 2791 2405 0,29 -0,52 325 2743 2323 0,317 -2,01 350 2695 2242 0,345 -3,79 375 2647 2163 0,373 -5,87 400 2601 2089 0,401 -8,26 425 2556 2017 0,43 -10,97 450 2511 1947 0,46 -14,01 475 2467 1879 0,49 -17,39 500 2424 1814 0,521 -21,14 525 2382 1752 0,552 -25,24 550 2340 1690 0,584 -29,74 575 2299 1632 0,616 -34,63 600 2259 1575 0,649 -39,93 Man,I hope this shows properly.
