Description

Weatherby took its flagship cartridge and paired it with one of the best monolithic bullets going, and the result is this 195-grain Hammer Custom load in .300 Weatherby Magnum. It is a lead-free, all-copper offering tuned specifically for the big Weatherby case, so you get the flat trajectory and hammering energy the cartridge is famous for without giving anything up downrange.

What Makes the Hammer Custom Bullet Different

These aren't off-the-shelf projectiles. Hammer Custom Bullets are CNC lathe-turned from a solid copper blend, with each one weighed and micrometer measured as it's produced for consistency that really shows up on paper. The design uses a hollow point nose that sheds its petals on impact for an immediate wound channel, while the blunt copper shank keeps driving for deep, reliable penetration. The 195-grain weight is a non-standard pick on purpose, chosen through testing because it delivered the best mix of accuracy and velocity out of the .300 Weatherby's large-capacity case.

Real Ballistics From the 300 WBY Mag Hammer Custom

Numbers back up the reputation here. This load leaves the muzzle around 3,075 fps with roughly 4,094 ft-lbs of energy, still carrying about 2,567 fps and 2,854 ft-lbs out at 300 yards. With a G1 ballistic coefficient of .550 and a 195-grain projectile, you get high sectional density that holds energy well past 500 yards. That combination of speed and retained punch is what makes this a genuine long-range elk and big game setup rather than just a paper spec.

Why Hunters Reach for This Load

If you're running a .300 Weatherby Magnum and want a copper bullet that shoots flat, hits hard, and prints tight groups, this is a strong pick. It's equally at home on a mountain hunt where a single well-placed shot matters and on the bench confirming your dope before the season. For hunters who want or need a lead-free option without stepping down in terminal performance, the Hammer Custom checks every box.

Frequently Asked Questions

Is the Weatherby 195gr Hammer Custom a lead-free bullet?

Yes. The Hammer Custom is a solid copper projectile with no lead core, lathe-turned from a copper blend. That makes it a good fit for hunters who want or need a lead-free load without sacrificing terminal performance.

What game is the 300 WBY Mag 195gr Hammer Custom best suited for?

This load is built for long-range hunting on big game like elk, mule deer, and other large species. The 195-grain copper bullet carries high energy well past 500 yards and penetrates deep, so it handles tough, heavy animals with confidence.

How fast does this 195-grain load shoot?

Out of a standard barrel it leaves the muzzle at roughly 3,075 fps with about 4,094 ft-lbs of energy. Thanks to the .550 G1 ballistic coefficient, it stays flat and retains energy well downrange, holding over 2,500 fps out to 300 yards.

Why does Weatherby use an odd 195-grain weight instead of a standard 180 or 200?

The non-standard weight is intentional. Through testing, Weatherby found that the 195-grain Hammer Custom delivered the best balance of accuracy and velocity out of the large-capacity .300 Weatherby case, which is why it landed on that spec rather than a more common weight.
