Dougy Posted June 16, 2015 Report Share Posted June 16, 2015 I always was of the understanding that if a bullet started off supersonic then the problem arises once it reaches the transonic zone it will then start to become unstable as the gyroscopic spin decreases. Not all will as you no doubt know being into long range shooting. If a bullet starts off subsonic then it doesn't have the same problem, yet it will tumble eventually as it slows. But what has the transonic stage got to do with a bullet that is all ready subsonic Quote Link to comment Share on other sites More sharing options...

On the subject of spin a lot of study reveals a lot of evidence to suggest a bullet will stop going forward before it ever ceases to spin!

Bewsher500 Posted June 17, 2015 Report Share Posted June 17, 2015 I watched Magpul video on the Art of the Precision Rifle shots at 1200yds and a mile with a .308 (that is well past transonic and into sub sonic) 18" plate - multiple hits comes down to bullet choice most of the time Quote Link to comment Share on other sites More sharing options...

Many a long range target event is conducted with them and they only just start off just above sound! Quote Link to comment Share on other sites More sharing options...
Bewsher500 Posted June 17, 2015 Report Share Posted June 17, 2015 true know a few 100yd boys who shoot black powder 45-.50cal muzzle loaders! Quote Link to comment Share on other sites More sharing options...
Underdog Posted June 17, 2015 Report Share Posted June 17, 2015 Patched ball rifles will exceed sound by a good amount but soon fall back under. The heavy slug guns rarely start over 1300 fps. Quote Link to comment Share on other sites More sharing options...
Dekers Posted June 17, 2015 Report Share Posted June 17, 2015 true know a few 100yd boys who shoot black powder 45-.50cal muzzle loaders! I know not what they were shooting but it was Black powder, and plenty of them on 1000 yards at Bisley last time I shot that distance.

Bewsher500 Posted June 17, 2015 Report Share Posted June 17, 2015 ha, just re-read my post its a 1000yd obviously!! Quote Link to comment Share on other sites More sharing options...
kent Posted June 18, 2015 Report Share Posted June 18, 2015 I always was of the understanding that if a bullet started off supersonic then the problem arises once it reaches the transonic zone it will then start to become unstable as the gyroscopic spin decreases. Not all will as you no doubt know being into long range shooting. If a bullet starts off subsonic then it doesn't have the same problem, yet it will tumble eventually as it slows. But what has the transonic stage got to do with a bullet that is all ready subsonic Nothing at all it will remain stable this in the case of a .22 sub. Stingers or WMR will enter a transonic zone though. It doesn't always effect accuracy the same way when a bullet slows and enters the transonic zone, its dependant on factors like air pressure and other stuff we cant easily predict. Actually shooting, well one swallow don't make a summer and only repeatability is relevant. The less predictability the lower the accuracy. Its like shooting a five shot screamer with a gun that's a reliable 1/2 MOA gun one day (it hasn't suddenly improved) or shooting a group outside the 1/2MOA (the likely hood is it aint busted). Accuracy is repeatability! Any who have actually competed at 1000 yards more than once with a .308 will get this to others I accept its goboldy gook. One day it goes great another unbelievably bad, depends on those unpredictable factors (I have BTW) but its just as relevant at far lesser range with any rim fire round that leaves the muzzle above the speed of sound, under and you will have no issue with transonic.
