Hello I got two more 3” magnum rounds to test for pattern and velocity. Winchester #X12XC3B5 3” 15 Pellet 00 Buck Copper Plated FEDERAL # PFC15700 3” 12 Pellet 00 Buck Flight Control wad The Winchester round really spread the shot out rather quickly, and velocity ok. Now the Federal round with the Flight Control wad is another story.. It held a tight pattern out to 21 yards and velocity is up there. Had a weird anomaly with the chronograph while shooting at the 14 yard target, so didn’t get a velocity. At 7 yards the shot is pretty much a slug. So for shooting out at extended ranges for buckshot this one is one to consider. Velocity is pretty impressive.. Could have taken this out farther than 21 yards and it still would have been acceptable..
