The Nosler® Partition® was the first bullet loaded in the Federal Premium® line, and it continues to be a standard for consistency and reliability. Its partitioned lead core allows the front half of the bullet to mushroom on impact, but keeps the back half intact for deep penetration.

Rated 5 out of 5 by from Perfect Performance on Deer and Hogs I've used these rounds in my Ruger M77 to kill a 4.5 year old buck, a couple of 3.5 year old bucks, and several hogs that topped out at 300 lbs. Full penetration on all of them. This caliber and bullet does not tear up the meat like some of the cheaper stuff. I've had nothing but good clean kills with great blood trails, and without a lot of vapor shock. It's the perfect combination for people who like to kill AND eat deer.

Rated 5 out of 5 by from Best factory 257 cartridge available I️ have used this round for over a decade and it is the best combination for the 257 caliber out of alll that are available. Accurate and dependable out to 300 yards on white tails.

Rated 5 out of 5 by from Excellent Hunting Round This round is the most accurate I have used in my Ruger 77 Mk II UL. Because of the accuracy, consistency, and devastating terminal effects, this is the only ammunition I regularly buy in lieu of handloading. Having taken numerous animals up to 350 pounds live weight with this round, I wholeheartedly recommend it for general big game hunting.

Rated 5 out of 5 by from Great Load For Deer If you don't load your own this load offers everything ever needed for deer hunting. Plenty of velocity for plenty of range and a great bullet.

Rated 5 out of 5 by from Great all around performer For a now less used round, Federal has offered a great all around cartridge for all the 300yd or less uses I can think of for my BLR. Hard hitting, accurate, and next to no recoil. Sure, I could spend the same money on custom made loads or reload myself and have a wider variety of options, but considering how little I shoot, this is a great one round fits all loading for me.
