Crosman Crosman 1377 pellet choice question

I have been working with 1377 trying to get it to group, I have been using Crosman 7.5g pellets but are not grouping very well 1 to 1/2 inches. I was curious as to what others are using that gets better results. tried every thing from 3 to 10 pumps. normally just use it for back yard plinking.
Would a heavier pellet work better than the lighter ones.???

10.3 gr CPHD Gave ne dime sized groups at 10 yards with factory sights, when I set up my first 1377.

Another vote for the JSB / AA / FX 10.3's. They shoot very well out of my .177's. However, every barrel is different so test them all. It's a rough job but someone has to do all that plinking. Soup cans beware.
