Understanding Trajectory and Ballistic Efficiency
One of the vital elementary variations between these bullet weights lies of their ballistic efficiency, notably the trajectory. The trail a bullet takes from the muzzle to its goal is essential, and the bullet’s weight dramatically influences this path.
Flatter Trajectory of the 150-Grain Bullet
The lighter 150-grain bullet, sometimes launched at a better velocity, usually displays a flatter trajectory. Which means that the bullet drops much less over a given distance in comparison with its heavier counterpart. This flatter flight path interprets to simpler aiming and a extra forgiving zeroing course of, particularly at typical looking ranges of below 200 yards. A shooter can usually “maintain lifeless on” the goal while not having to compensate for important bullet drop.
Extra Curved Trajectory of the 170-Grain Bullet
The heavier 170-grain bullet, whereas touring at a considerably decrease muzzle velocity, experiences a extra curved trajectory. This is because of its larger mass, which implies it’s extra affected by gravity over time. Whereas the drop is a drawback, the elevated mass affords advantages on the level of impression. The shooter should take into account this curve and make changes to their level of goal at numerous distances, requiring a deeper understanding of the rifle’s ballistics. Understanding this arc of journey permits the shooter to compensate precisely.
For instance, take into account a state of affairs the place a shooter zeros their rifle at 100 yards. At 200 yards, the 150-grain bullet may drop, say, 4 inches.

The shooter must know the trajectory of their ammunition on the distances they hunt.
The extra curved trajectory of the 170-grain bullet necessitates a extra calculated strategy, however the rewards could be important.
Vitality Switch and Terminal Ballistics
Past the trajectory, one other important space of comparability is the way in which every bullet interacts with its goal. This facilities on power switch and the terminal ballistics, which affect how a bullet performs upon impression.
150-Grain Bullet Vitality Switch
The 150-grain bullet, resulting from its larger velocity, can expertise extra dramatic growth. The elevated velocity helps the bullet open up upon impression, creating a bigger wound channel. The speed of growth is affected by the bullet building, which we’ll come again to.
The lighter bullet can even expertise faster fragmentation relying on its building. This may end up in substantial power switch to the goal, resulting in a fast knockdown. Nevertheless, it additionally may end up in much less penetration, which means that the bullet may not attain the important organs of bigger sport if the shot placement is just not good or if the goal is angled.
170-Grain Bullet Penetration
The 170-grain bullet excels in penetration resulting from its larger mass and sectional density, which is the connection between the bullet’s weight and its cross-sectional space. A better sectional density means the bullet is much less more likely to deflect upon impression and is best in a position to drive by way of bone and muscle.
The 170-grain bullet, with its slower velocity, may develop much less drastically. Which means that it is extra more likely to maintain collectively and retain its weight, contributing to deeper penetration. This turns into essential when looking bigger sport or in conditions the place the goal is more likely to be closely muscled or shielded by brush.
The development of the bullet considerably impacts its terminal efficiency. Gentle-point bullets are designed to develop on impression. Hole-point bullets characteristic a cavity within the nostril that encourages fast growth. Managed growth bullets, like bonded bullets or these with strengthened jackets, are designed to carry their weight and penetrate deeply. The proper bullet kind for the looking state of affairs is likely one of the most vital issues.
Selecting the Proper Weight: Functions and Suggestions
The selection between 150 and 170 grain bullets finally depends upon your supposed use.
Looking Functions
For looking, the 150-grain bullet could be a wonderful alternative for whitetail deer at reasonable ranges, particularly in open environments.

The 170-grain bullet usually shines if you’re pursuing bigger sport. It is well-suited for heavier-bodied deer, corresponding to these discovered within the northern areas of the US. This bullet is a wonderful alternative for looking in dense cowl or in areas with brush, because it excels at penetrating foliage and sustaining momentum by way of bone and muscle. The added weight will increase your possibilities of an moral and efficient harvest, notably at barely longer ranges.
The terrain and capturing setting play a job in your choice. Hunters in brushy areas may profit from the larger penetration of the 170-grain bullet. Hunters in additional open fields might discover the flatter trajectory of the 150-grain bullet advantageous.
Goal Capturing and Plinking
For goal capturing or plinking, the 150-grain bullet could be advantageous resulting from its flatter trajectory and doubtlessly decrease recoil. This will result in quicker follow-up photographs and elevated accuracy at widespread ranges.
