    Nitrex .243 Win 100 gr Grand Slam rounds

    Posted by Kent Knickmeyer on Mar 26th 2026

    While I’ve not fired any of the recently purchased shells, the boxes and the shells are in pristine condition. I bought 1 box of this ammo in 1995, on the recommendation of a dealer in Casper Wyoming who patiently listened to my frustration at the distance I’d had to follow an antelope which I’d shot 4 times in its chest cavity with Remington Core Loct ammo. I’ve since then shot 2 antelope and 5 whitetail with the Nitrex rounds. Both antelope and three of the deer were dropped where they stood, the other two deer dropped within 25 yards of where they were standing when shot. I began searching for additional supplies of this ammo around 15 years ago, only to discover it is no longer being manufactured. I am delighted to have found this new supply.
