Alot of guys dislike and down the Traditions line of ML , BUT I have owned 3 of their rifles in the past and EVERY one of them were Tack drivers @ 100 yds and closer !
I had never shot Saboted Bullets threw them BUT these were Great Conical Shooters For Sure !
Traditions Buck Hunter - 90gr Pyrodex Select & 350gr Maxihunter with a over the powder Wad !
Traditions Tracker 209 - 90gr 2fg 777 & 370gr Maxi Ball with Wad
Taditions Tracker 209 - 75gr 2fg 777 & 460gr BullShop Conical With Wad
I would be willing to bet that if he tried
100gr 2fg 777 with a 300 gr Hornady XTP Mag with Harvester Short Sabot , The results would be Good !
Good LUCK and Shoot Straight
