    Range Report Spindrift Calculation??

    Re: Spindrift Calculation?? I think that we all or at least most agree that SD exist it is the amount of it out to 1K that is in great dispute. Brown Dog claims to use .36 Mills with his 308 and 155 grain Scenars. That's a lot of Spin Drift for 1K IMHO

    Range Report Spindrift Calculation??

    Re: Spindrift Calculation?? Maybe brown Dog will calculate the spindrift for the various bullets and calibers that we use. A very nice gesture indeed.

    Range Report Spindrift Calculation??

    Re: Spindrift Calculation?? That has been my contention from the start spin drift is not calculateable before hand if one is shooting a bullet that exhibits a noticable amount of spin drift, it must be shot to determine the amount that needs to be accounted for. Exbal has a spot for the...

    Range Report Spindrift Calculation??

    Re: Spindrift Calculation?? No it ain't rocket science and 3 tenths mill adjustment for sprin dirift at 1K is a miss on the 10 inch wide target that I shoot. If you get 10.75 inches of spin drift with a 155 bullet then you are an unlucky individual. I am solidly with LowLight on this one..

    Range Report Spindrift Calculation??

    Re: Spindrift Calculation?? Brown Dog, Lowlight ignores spin drift to 1K and that's ok because as you say it works for him. I ignore spin drift and hit what I am shooting at and you can my intelegence into question. I hope that one day we can continue this discussion in person eye...

    Re: Spindrift Calculation?? You are spot on IME. As you posted ealier your shooting buddy made a hit at 1997 yards with a 7 WSM with no SD correction and that says it all IMHO. If people can't deduct the facts from that then I am at a loss

    Re: Spindrift Calculation?? Yea I'm fairly certain that my scope is tracking properly. If my scope reticule was not level when adjusting elevation then the windage would not stay in the middle of the target at varying ranges How about this at 975 yards and again no spin drift...
