I thought this question would trash the BDC. On you-tube, as you might suspect the prostaff guys really over sell the product like some slicer dicer at the state fair. Like you-for shells my first thoughts are core lokts in 180. On those videos they use a .308 at 2700 in 180 so they should be the same-or very close-to the drop of a 180gr in .06. As I recall at 2700fps the .308 and .06 with the same shell and speed should drop the same. On the plus side, your eye goes to the crosshairs. You need to carry a rangefinder for long shots anyhow. The only question on a long shot, is it closer to 200yds or 300yrds. I'm not going to shoot 180 grains 400yrds. They have shells for that but I'm a core lokt type myself. If I'm shooting at something that's way out there and I have the correct load sighted in, you can take a 400+and aim knowing your going to kill quickly. You can't say that if you have to Kentucky hold--although you still have to guess windage. I feel more shots are missed by drift anyhow. But, I could have returned it, but now I see that in a couple years it will come real natural. It already does: just looking at mailboxs down my road the extra power over a 3x9 is useful. I can read the names two blocks away. I got more power for sighting-in perfect. Now my shots will be dead center at 100yrds. That way at two hundred it should be close to perfect left to right. The drop is well known. At three hundred-that critcal range-if it's still on it will also be at greater ranges. Like I said, the drop is well known and starting to drop faster. The real question is the wind. If you put the slug inside the circle it should be in the kill zone. Anyway you cut it, it is still easier to find the correct ring on your scope to find the kill zone than having to guess both drop and windage. Like I said, it wont be tomorrow, but in a year it should feel pretty good. In the mean time it will be good-old core lokts in 180 and shooting at a reasonable distance with the crosshairs. Thanks for the comment Carolina, good luck with your Tikka. One final observation-that scope is well made and very nice looking. It appears plenty sturdy, possibly their best effort to date, and remember I could have returned it no questions asked. But I can see myself getting better and can't wait to have some real fun learning to master the new more powerful BDC prostaff 4x12, first at the range than the field. Thanks for hearing me out.
