1 year agothe ammo is perfect for deer and black bear. The quality is a ten and the performance is what you would expect from Hornady ammo.

1 year agoI have a custom built 257Roberts & with these rounds it’s an absolute tack driver & devastating on deer.

1 year agoDon’t believe the ad. Went to my Sportsman to purchase this but got the blank stare when I asked about the product, hasn’t been on the shelf for a year +.

1 year agoNot super happy with the accuracy of these. I was shooting hand loads so I was spoiled. I can’t get those anymore, and this was the only ammo I could find in this caliber. 2-3” groups at 100 yds out of my Winchester 70 XTR Featherweight.

1 year agoHaven’t shot this ammo yet, but have always had a good experience with Hornady Superformance. Shipped quick and was packaged well. Will update if any performance issues. Not to mention this ammo is super hard to find let alone for this price!

1 year agoSo far they have perform great on paper, average group at 100 yard -5/8" through a 24" 1:10" right hand twist barrel. Will test it on deer next hunting season RV

1 year agoClean firing and accurate. Wouldn't expect anything less from Hornady. Hard round to find and Hornady comes through as usual!
