I have same gun with 20 inch barrel, killed many birds with mag blend and jelly head .665 , loved nitros as well, switched to Indian creek .665 an got around 15-20 pellets more in 10" at 40 yards. Average a little over 200 pellets in 10inch with long beard 6's with IC .665. Bad to bone with tss, was only way to break 300 pellets in such a short 3 inch gun.
