10mm Auto – 200 gr Hard Cast Flat Nose – Underwood Ammo (UA248) – 200 Rounds

In bear country or on a hog hunt, a 10mm load has to punch deep and hold together, not expand and stop short. Underwood Ammo 10mm Auto 200 gr Hard Cast Flat Nose, MPN 248, is built for that kind of penetration. This listing is a bulk case of 200 rounds, enough to practice with your woods carry load until follow-up shots are second nature and still keep plenty on hand for the trail.

The 200 gr hard cast flat nose bullet is a deep penetrating, non-expanding design. The wide flat nose crushes a broad channel while the hard cast construction keeps the bullet intact through heavy muscle and bone, which is why hard cast 10mm is a common choice for bear defense and for hunters who expect to break heavy shoulder bones. The bullet carries Underwood’s Black Cherry polymer coating. Underwood rates this load at 1,250 fps and 694 ft-lbs of energy, with a sectional density of .18.

This 10mm bear defense ammo runs in 10mm Auto pistols like the Glock 20 and Glock 40, along with other 10mm handguns. It is made for hikers, hunters, guides and landowners who carry in bear country, and for hunting hogs and medium to large game where penetration matters more than expansion. Because a hard cast load may recoil differently than your range ammo, buying the 200-round bulk case lets you practice with the exact 10mm hard cast load you carry, confirm reliable feeding in your pistol, and pay less per round than buying single boxes.

Underwood Ammo 10mm Auto 200 gr Hard Cast Flat Nose is made in the USA and is new production ammunition, not reloads. It is loaded in nickel-plated brass cases with boxer primers, and it is non-corrosive. The nickel-plated brass is reloadable, so handloaders can save their fired cases for future 10mm loads. The case ships in the original factory packaging as 10 boxes of 20 rounds, for 200 rounds total.
