.177 Lead-Free Air Pellets & Airgun Compatibility - Expert Advice

Question
Hello, Mr. P. Ryan.
I'm wondering if you know the lenght of in mm .177 PROMETHEUS lead free pellets. Is it OK to use them with Crossman air gun, if they were to fit?
And, would you recomend air gun (spring) that does more then Crossman's "435" fps.
Thank you,
Allen


Answer
Hey Allen,
         As long as your crosman is specified ".177" then the lead free pellets will work on them. I do not know the length, but that wouldn't matter. And as for the fps, these pellets are suitable for 435. Thank you, don't hesitate to ask any follow ups.
