I have a 1322 24" that does 707fps at 20 pumps and 735 at 25 pumps with 14.3 gr. Regards, Tom
AC FT piston, valve, and hammer spring. Mellon power adjuster, hollow probe, and solid pin pivot. Crosman steel breech. Can't remember who makes these, a brass transfer tube with tubing around it. Regards, Tom
The difference between a 24" barrel and an 18" at the 700 fps level in a 2289 will be roughly 40 fps.... The 12" barrel will lose roughly another 60 fps, making about a 100 fps difference between a 12" and 24" barrel.... Barrel length is your friend for power, especially in a "pump and dump" gun where the valve is still open when Elvis leaves the building....Bob
