I don't have a barrel for the Encore in 300 Whisper but I've had a 14" Contender barrel now for several years and even had a centergrip XP-100 rebarreled to 300 Whisper a few years back (both with 1 in 10 twists) when I was competing in IHMSA silhouette matches hot and heavy.....sweet little round and very accurate.
I never hunted with the Contender or XP but I did loan the Contender to a buddy one fall and after working up a hunting load he took two deer with it that year....both right at 125 yds. and both were one shot kills.
If interested the below silhouette load shot extremely well in both the XP and my Contender barrel.
221 Fireball brass....Rem. 7 1/2 BR primer....Sierra 168 gr. # 2200....18.5 grs. of AA1680.
