Description

Sierra 7mm 140gr HP Boat Tail #1912

Sierra GameKing Bullets are designed for long-range hunting, where the extra margin of performance can make all the difference. GameKing bullets have a boat tail design that provides hunters with the ballistic advantage found in match target bullets. The boat tail's streamlined tapered base reduces drag significantly, resulting in higher retained velocity, greater striking energy, a flatter trajectory, and less wind drift than comparable flat base bullets.

Best Suited For

This bullet is ideal for:

  • Medium game hunting (deer, goats, pigs)
  • Hunters wanting accuracy + reliable terminal performance
  • Reloaders seeking a modern hunting bullet with better aerodynamics
  • Use in cartridges like 7mm-08, .280 Remington, 7mm Remington Magnum, 7mm SAUM

When To Use It

Use the #1912 HPBT when:

  • Hunting at short to long ranges where trajectory matters
  • You want better BC and wind performance than flat-base soft points
  • You need consistent expansion without tip damage (no exposed soft lead tip)
  • Developing loads for modern 7mm hunting rifles

It’s especially effective in open terrain where wind drift and drop control become important.

FAQs

Q: Is this a match bullet?
No. Although it has a hollow point, it is a GameKing hunting bullet, not a MatchKing.

Q: Is it suitable for large game?
Yes for medium game; for larger animals (e.g., elk/red deer), heavier bullets (150–175gr) are usually preferred.

Q: Does the hollow point improve accuracy?
Accuracy is excellent, but the HP design is mainly for controlled expansion and consistency, not purely match precision.

Q: Real-world performance?
Field testing reported clean pass-throughs and strong expansion, even on angled shots.
