    338ARC “Slow Jam” 300gr Sub

    Posted by Sean Ryan on Nov 6th 2025

    I have taken an 8pt and 10pt buck so far this year with the 338 ARC “Slow Jam” 300gr subs. Out of an 8.5” 1:8 KAK barrel. I was about 60-80y on both shots. Both deer only went about 10y after being hit. The first deer the round passed all the way through, the second round was recovered in the 10pt. Only one of the peddles on the round that was recovered in the deer had opened, but did catastrophic damage to the heart. Both rounds were extremely accurate and very quiet. I would highly recommend this loading over the Hornady 307gr subs.

    Best .338 arc rounds I’ve used, very accurate. very reliable. Def worth it. Shot out of 8inch barrel with a 1-5 twist rate.
