Are beeman Kodak pellets accurate in marauder .25

Everyone is out of jsb kings and just wanted to know if beeman Kodiak match are good in marader Hn barracudas. Are getting 2. Inch groups at 50 they are very accurate at 30 but they spread right out. Also have any of you guys tried cphps in 1377 I tried them today at 10 yards they got about 2 inch groups some missing the target destroyers got .25 inch groups too bad I only have 7 left.
