Question On .30-30 And .30-06 Rounds

[ThatZX14Fella]

You're shooting down towards the ground, it looks pretty thickly wooded also so trees should help stop it, and according to the first picture, you have plenty if distance to work with. I believe you're good.

Roger, since I know you to be a detail oriented guy, a bullet doesn't technically begin to fall the moment it loses support from the barrel.

 

All bullets rise, to some degree, before falling to zero and then to its final impact.

 

Wayne, what force on a spinning bullet would cause it to defy gravity?

 

I have a hunch you might be confusing bullet drop with 'point blank' range.

The axis of the bore is intentionally angled upward from the axis of the scope, which crisscross (X) at 'point blank' range.

If you fire the rifle upside-down (scope on bottom), the bullet will now be angled downward toward the ground.

But in both cases, the bullet begins to drop the instant it loses support of the barrel.

I stand corrected. Thanks Roger.

>> "How far will both of these rounds travel before they start to drop?"

No matter how big or how small the cartridge, the bullet begins to fall the instant it loses support of the barrel.

Furthermore, ALL bullets drop at the same rate-of-speed, regardless of their forward velocity.

A loose bullet that rolls out of your hand will hit the ground at the same instant as the bullet shot from a horizontal rifle.

 

The bullet from a 30-06 has a flatter trajectory and greater range than a 30-30,

but the 30-30 is a better "brush-bucker" and has a shorter range.

However, the bullet from any rifle will be deflected by brush, so accuracy is as important as range.

The answer to the question is to rephrase the question; How far will the bullet travel before it hits the ground?

 

Roger's answer is spot on, they both will hit the ground at the same time.

 

Without getting persnickity about theories of gravity, fluid dynamics, coefficients of friction, atmospheric conditions, drag, blah, blah, blah...Let's assume a few things

 

Both bullets are fired level from a should height of 60",  both bullets will be in the air for 1 second. (yes, I realize that it is more like .71 sec but work with me here)

 

The 180 grain 30-06 has a muzzle velocity of about 2900 fps, dropping to 2300 fps at 200 yards and finally hitting the ground around 600 yds

 

The 150 grain 30/30 hollow point has a muzzle velocity of 2400 fps dropping to 1700 fps at 200 yards and finally hitting the ground around 390 yds

 

The 30/30 flat nose slows down even faster and will hit the ground around 300 yards.

Mc496,

 

Look at  exterior ballistics this way:

 

Generally speaking Gravity pulls all objects down at the rate of about 16 ' per second, therefore bullet velocity is the major factor in effecting a bullets trajectory

A 150 grain 30-30 has a muzzel velocity of 2400 f.p.s. the 30-06 150 grain bullet goes out at 2900 f.p.s.

 

The 30-06 is by far the best long range performance.

The 30-30 is further compromised because its poor ballistic coefficient with the flat nose required to keep it safe in the 30-30 tube magazine.

 

Google the mid range trajectory specs for each and you can see the specific amount of drop at specific yardage for each.

 

The 30-30 however is arguably the best selling deer rifle ever made because many great qualities you didn't consider.
