Anybody have suggestions where to find ballistic and trajectory charts for mainly .177 cal. I am shooting a Diana 350 magnum (approx. 1250fps) with 10.65 barracuda pellets. I am curious for trajectories out to 100 yards. Any assistance appreciated.

Looks like your pellet has a BC of around .020. Here's a pretty good list of tested BC's. https://hardairmagazine.com/ballistic-coefficients/You should be able to plug in your pellet weight, velocity, and BC into one of the ballistic calculators and be in business.

You really get 1250fps with 10.65gr pellets?

You really get 1250fps with 10.65gr pellets? That seems a little high to me also. I was thinking maybe around 950 fps or so for that pellet?

I believe the RWS 350 is rated at 1250 fps with light/alloy pellets. My Walther Parrus is rated at 1300 fps.. It actually does break the sound barrier with 7.3 - 7.5 gr lead pellets but only gets 970 fps with the 10.65 gr. Barracuda match. The heavier pellets have proven much more accurate in my rifle.

To verify, When I stated 1250fps, I was just using the manufacture rated specs. I have no chrono, and not trying to splits hairs for 100% accuracy. Just looking for somewhat ballpark trajectories.

This will probably get you in the ballpark, with a 40-yard zero.
