I shoot them 300gr in my TC triumph, and my Knight LRH. 1" groups or less in each gun. The triumph likes the standard crush rib sabot over 110gr volume of BH209. The larger bore LRH likes the RED crush rib sabot over 120gr volume BH209. I have 50 of the 260gr bullets to try, but havent got to them yet as the 300gr bullets shoot so well out of my guns.
