bullet accuracy short/fat or long/skinny
 

Generally speaking, which bullet is more accurate?? 150 grain 30 caliber or 150 grain 7mm all other things being similiar?

With each fired in a high quality gun( rifled for the bullet in mind) in a handload worked up for that particular gun ,I doubt that you could tell the difference.

Theoretically speaking, a longer bullet with an ideal stability spiral would be more accurate, basically because it has a longer horizontal axis upon which it rotates, giving it a better aptitude towards stable travel.

HOWEVER, as with many theories, this one has been proven wrong time and time again...I'm assuming, going out on a limb, that you're comparing a .30-06 or .308 to any of the 7mm mags, in any circumstance, the inherent accuracy advantage going toward the 30 cals by far. As far as any hunting scenario is concerned, I agree with SJ, you'll never notice the difference, nor will your game. In most cases, with ideal spiral rates obtained and proper loads, bullets, and guns all matched for eachother, you'd have a difficult time telling the difference on the range even out to a half mile I'm betting.

Screw the 10 ring, keep them in the zero!!!

What Stubble said would be my guess also .

Thanks for the replies, and I probably shouldn't have stipulated the 30 cal and 7mm. I was just curious if in picking a gun for, say deer hunting, would one see an advantage in shooting a light for caliber bullet (short/fat) or heavy for caliber bullet (long/skinny) if targeting a bullet weight of say 150 grains.....I'll buy the horizontal axis theory, though I am certainly no physicist.....

Or another way to ask the same question, is there typically an accuracy advantage in shooting heavy or light bullets for caliber? ie 140 grains or 180 grains in a 30-06??

Let the gun tell you what it prefers.Some guns shoot better with lighter bullets and some with heavier bullets.The style of bullet can also be a big factor where accuracy is concerned.

Bullet length and rate of twist are very important, but bullt QUALITY is the most important factor. How concentric are the bullets? This is what determines how far each slug will deviate from rhe axis of the center of the rifle's bore, if rhe bullet is being spun properly.

Keep yore powder dry!!

For the most part, I see guns shoot heavier bullets better. Especially in the .308 bullets with a 1 in 10 or 9 twist. With a heavier bullet, you get better BC, better wind drift also.
