Ive no idea why i thought it, but i always assumed you were shooting much faster than that. Like 2500+. Looking at this, that bullet doesn't lose as much speed as i thought it would in 1k yards.

The load is the maximum allowable of BH in the matches. I can get to 2500fps
I see the surgeon on Wednesday and my first question to him will be: Can I shoot?

Looks like that bullet goes subsonic between 700 and 800 yds.
It's kind of funny that my black powder ctg. bullets go subsonic at about 200 yds. +-
The speed of sound is dependant on the temperature but is approximately 1125 FPS at 68 degrees F.
Encore.......what is the approximate wind deflection of your bullet for a 5 and 10 MPH full value wind?
Will your program figure that out? I'm curious. X

Yes, the program will give you an approximate.

Zero wind at 1,000yds. Note spin drift.




5mph wind



10mph wind

Am I reading your chart correctly? 7.6 MOA deflection at 5 MPH and 14.1 MOA at 10 MPH at 1000 yards. I didn't expect so much. Believe it or not, the general wind deflection formula [for BP CTG ] I use from 800 to 1000 yards for a full value wind is a "mile a minute" which doesn't seem that far off from your chart. A really funny thing is my BPC bullets start out at around 1300 FPS muzzle velocity. Yours have just SLOWED DOWN to that at 600 yds! Interesting. X

You're reading it correctly. When we shot at Atterbury in June, the "fish tailing" winds created 12moa changes.

Very interesting information thanks for posting.
