The Rowland will launch the same bullet nearly 1700fps. The Rowland will launch 230grs 1450fps. The 265gr Beartooths will leave the tube at 1300+. reflex264


Thank you for the info and the pictures. I was wondering if a 9" G21 barrel shoot in 45 Super will get close to the 460 Rowland. On your block, you use a comp on both the 45 super and 460 Rowland.

Edit: What Barrels and comps are ya using for the 45 Super and 460 Rowland?
