Description
The Winchester Super-X Power-Point is one of the most reliable hunting rounds you'll find. This particular load pairs that classic design with the flat-shooting speed of the .270 WSM cartridge, giving you genuine performance gains over the standard .270 Winchester. You get roughly 150-200 fps more velocity than the regular caliber, which translates to better energy retention downrange without the recoil of larger magnums.
Proven Power-Point Design
Winchester developed the Power-Point back in the 1950s and it's been killing game effectively ever since. The design is straightforward but proven: an exposed soft tip with a copper jacket featuring strategically notched jacket mouth that promotes consistent expansion. The alloyed lead core maintains excellent weight retention while the tapered jacket gives you controlled expansion for penetration when it counts. This isn't cutting-edge technology, but that's precisely the point. The Power-Point has simply done the job for generations of hunters.
The .270 WSM Advantage
Introduced by Winchester in 2002, the .270 WSM applies their short-fat case design to .277-inch bullets and produces noticeably faster ballistics from short-action rifles. Your 150-grain rounds hit the muzzle at 3150 fps with 3304 ft-lbs of energy, which keeps the cartridge flat-shooting and effective at extended ranges. The 150-grain bullet in this caliber is optimized for medium game like whitetail and mule deer, with enough sectional density to deliver the penetration you need.
Field Ready
Each box holds 20 rounds of new production ammunition loaded in reloadable brass cases with Boxer primers. Non-corrosive and reliable in all conditions, these loads will serve you whether you're hunting timber stands or open country. The combination of this 150-grain weight with the WSM's velocity makes for a well-balanced hunting load that handles medium distances without complications.

Frequently Asked Questions
What game is this .270 WSM 150 grain load suitable for?
This load is designed for whitetail deer, mule deer, antelope, and black bear. The 150-grain bullet offers good sectional density for medium-sized game, with velocity that maintains energy to reasonable hunting distances. Shot placement remains the most important factor regardless of energy figures.
How does the .270 WSM compare to the standard .270 Winchester?
The .270 WSM is noticeably faster, delivering 150-200 fps more velocity with 150-grain bullets from a short-action rifle. This means flatter trajectory and better energy retention downrange. Both cartridges use the same .277-inch bullet diameter, so you have access to the same hunting bullet selection.
Are these rounds reloadable?
Yes, they come in new brass cases with Boxer primers, so reloaders can reload them. The ammunition is non-corrosive and standard loading practices apply. Check your reloading manuals for proper specifications.
What's the effective range for this ammunition?
With the 150-grain Power-Point at 3150 fps, you can reliably hunt medium game out to 300-350 yards with good shot placement. Energy retention is solid at these distances, though like any hunting scenario, closer shots are preferable for consistent results.
