snipers eye Posted March 21, 2014 Report Share Posted March 21, 2014 hi all,are all 223 bullets affected by wind,or is there one i can use out to 200 yards in a 20-30 mph crosswind,?reason for asking is its bloody windy a lot of the time during winter,my hmr is stuck in the safe most of the time,thinking of changing it for 223,thats of course if there is a bullet not affected by wind,thanks Quote Link to comment Share on other sites More sharing options...
Albert 888 Posted March 21, 2014 Report Share Posted March 21, 2014 All bullets are affected by wind. A 223 bullet will be better at 100-300m though. If you have a look on Google you should be able to find a wind chart for target shooting and see how much the wind really does affect the path of the bullet. Im currently fighting against the wind only practice and good wind reading skills will sort me out though. Good luck. Quote Link to comment Share on other sites More sharing options...
Bewsher500 Posted March 21, 2014 Report Share Posted March 21, 2014 (edited) The heavier the bullet the less it moves in the wind at any given speed Only practice and skill at reading wind ALL the way to the target can help you there I am afraid, no amount of BC studying and digital apps will help you read a wind and work out drift at a particular speed or angle get a .270! saves reading most winds inside 200yds!

casts_by_fly Posted March 21, 2014 Report Share Posted March 21, 2014 As above, all bullets are affected. Heavy bullets are affected less. Fast bullets are affected less. High BC bullets are affected less. Are you limited to 223? A 25 mph crosswind is a lot. For S&G I did a few calculations. The 40 gr Vmax from a 223 (3600 fps) will drift 14" at 200 yards. A 52 gr Amax (3400 fps) will drift 12". The 80 gr Amax (2700 fps) will still move 8". Even if you push the 80 gr Amax at 3000 fps (22 BR maybe?) you're still at 7". So with a 223 you need to consider the wind. If you want less drift, you need a bigger gun. Sticking to bullets i know at speeds I know are possible, the 165 gr Ballistic tip at 30-06 speeds (2850fps) is still 7". The 150 gr version (at 2950) is 8". Taking it to the extreme, the best case I can find is pushing a .338", 300 gr match king at 2850 fps which is 338 Lapua territory. You can get the drift down to 4.5", so still not minute of fox or rabbit if you don't read the wind. Long story short, if you're shooting in that kind of wind, get a wind meter and set out some permanenet flags. thanks, rick Quote Link to comment Share on other sites More sharing options...
snipers eye Posted March 21, 2014 Author Report Share Posted March 21, 2014 thanks alot lads for the info,im thinking ill just have to wait for calm days,or invest in a shottie and dog Quote Link to comment Share on other sites More sharing options...
casts_by_fly Posted March 21, 2014 Report Share Posted March 21, 2014 or learn to read the wind. If the wind is semi constant then you can know what your bullet is drifting. If you know that your bullet is drifting 12" with a 25 mph cross wind at 200 yards and you can estimate that the wind is 25 mph, then hold off 12" (or dial it in) and take the shot. As long as you are within a couple mph and 20 yards in your estimations, you should be pretty close. If you get a range finder and a wind meter, then you can know right there and have either a lookup table printed out or carry an app on a smart phone. It isn't rocket science, but it takes a little prep work. rick Quote Link to comment Share on other sites More sharing options...
kent Posted March 21, 2014 Report Share Posted March 21, 2014 It don't matter much what you shoot everything drifts in the wind. The neatest trick is face directly into the wind, as long as the wind doent react with contours you can quite effectively shoot directly into it with nil value. To qualify everything drifting a .243 shooting an 87 grain BT with a far higher BC at a full 3300 fps is going to drift near enough 6 1/2"- 7 " in a full value 25 mph wind at 200 yards Quote Link to comment Share on other sites More sharing options...
Dougy Posted March 22, 2014 Report Share Posted March 22, 2014 Me personally would stop in if the wind was over 15 mph. For live quarry anyway. Nothing can be that desperate. Targets a different matter, get out and get some experience and log you finding. Me personally would stop in if the wind was over 15 mph. For live quarry anyway. Nothing can be that desperate.
