I shoot sabot slugs frequently and can say that yes, every barrel has its own likes and dislikes. But generally speaking, your pro-hunter barrel is a 1:28 twist. the faster twist rates usually like smaller diameter, lighter, faster sabots. Such as the remmy core lokt's hornady sst's, partition golds and the list goes on. Whereas barrels such has a Hastings barrel boasting a 1:34 twist rate, they usually will fair best with heavier, close to bore size saboted projectiles not exceeding 1700-1800 fps. velocities. buckhammers, lightfields (hybred elites are extremely accurate out of my hastings), sometimes copper solids, some brenneke's and the list goes on. key point is that they are near bore size, and in the 1500 fps-1800 fps range for slower twist barrels
