Is Barnes TTSX G1 or G7?

Is Barnes TTSX G1 or G7?

Barnes lists the . 392 BC for the 130gr ttsx. It is a G1 BC and requires that you use the G1 drag function. The G7 BC will be closer to 0.19 or so.

What is G7 form factor?

In particular, form factor is a number that relates the drag of a bullet to the drag of a standard such as G1 or G7. G7 form factors for long range bullets are from 0.95 (low drag) down to 0.88 (very low drag) for most typical long range bullets.

Do you want a high or low ballistic coefficient?

A bullet with a high BC will travel farther than one with a low BC since it will keep its speed better, resist the wind better, and “shoot flatter” (see external ballistics). When hunting with a rifle, a higher BC is good for several reasons. A higher BC results in a flatter flight.

What does G1 ballistic coefficient mean?

Typically, the higher the number, the lower the drag of the projectile (low negative acceleration), and the better the bullet will cut through the air. G1 – also known as Ingalls, G1 projectiles are flatbase bullets with 2 caliber nose ogive and are the most common type of bullet.

What is the difference between G1 and G7?

5 days ago
G1 – also known as Ingalls, G1 projectiles are flatbase bullets with 2 caliber nose ogive and are the most common type of bullet. G7 – Bullets with the G7 BC are long 7.5 degree boat-tails, with 10 caliber tangent ogive, and are very popular with manufacturers for extremely low-drag bullets.

What ballistic coefficient does Barnes use?

Ballistic Coefficient: . 499 (. 300 Win. Mag.) Muzzle Velocity (advertised fps): 2825 (6.5 Creedmoor), 3140 (.

What caliber has the best ballistic coefficient?

Originally Answered: What cartridge has the highest known ballistic coefficient? The 7mm Remington mag and the 6.5 creedmore are two of the most currently used long range cartridges at this time in competition shooting.

Which is better G1 or G7?

G1 and G7 both measure the aerodynamic qualities of a bullet but use different models to do so. It is argued that the G7 drag function is more accurate when calculating bullet drop of longer, sleeker bullets while the G1 drag function is more accurate when calculating old fashioned, flat base bullets.

What’s the difference between G1 and G7?

G1 – also known as Ingalls, G1 projectiles are flatbase bullets with 2 caliber nose ogive and are the most common type of bullet. G7 – Bullets with the G7 BC are long 7.5 degree boat-tails, with 10 caliber tangent ogive, and are very popular with manufacturers for extremely low-drag bullets.

What is the difference between a G1 and G7 bullet?

The G7 standard projectile more closely represents today’s boat tail bullets and assigns them a more realistic BC than does the G1. Most importantly, the G7 also renders an accurate BC at all velocities for a boat tail rifle bullet. Thus, bullet makers are beginning to offer us G7-based BCs.

What is the difference between the G1 and G7 drag functions?

The G1 model is based off of a stocky, flat base bullet template while the G7 model is based around a match style, boat-tail bullet template. It is argued that the G7 drag function is more accurate when calculating bullet drop of longer, sleeker bullets while the G1 drag function is more accurate when calculating old fashioned, flat base bullets.

Is the G1 or G7 BC better for supersonic flight?

The page includes a chart that shows how the G1 and G7 BC change based on the velocity of the bullet, and it also quantifies the variance of each type of BC over supersonic flight. Clearly the G7 BC is a better fit for this bullet, and 99% of the other bullets covered in the book.

What is the G1 standard projectile?

The G1 standard projectile is adequate for describing the BCs of (l. to r.) short, blunt bullets, pistol bullets and many jacketed rifle bullets, but produces misleading BCs for boat tail and secant ogive rifle bullets. The latter two BCs should be based on the G7 standard projectile.
