Sometimes you get a little luck.....I cut a piece of copper tube for a spring spacer by just guessing the proper length to raise the fps to the limit for a non pal Phantom .22....worked out perfect...
Started out with 432 fps average /445fps high over 25 shots with a 14.3 gr...and it now shoots an average of 494.1fps over 25 shots and an absolute high of 499.7fps over 51 shots total..…Cool...
Work done...new seal sized to fit....spring tube liner....polished top hat...polished guide and spring ends....plus I just guessed it right for the length of the copper spacer.... :D

Good job! Pretty safe to say its still a non pal gun, especially after 51 shots over a chronograph. I got my .177 Optimus to 492 fps max and decided not to push it, good enough.

It appears you have read Chevota's excellent guide on tuning Springers :)

I bought the Phantom as it's a solid value in the Canadian sub 500fps market, and with a little effort can be a joy to shoot.
I'm guessing your pellet of choice is the Crosman Premier Hollow Point; or did you just select that weight in pellet to maintain the sub 500fps watermark..?

Clearly a labour of love MyCrosman, well done..!

I doubt there is a better airgun tuner than Chevota.....Never read his guide on tuning springers.... If I had I probably would have saved myself some time over the years...but learning through experience has its own reward.
I prefer that route…..but when I DO get stuck on something....I certainly contact the Chevotas and Rsternes of the airgun world...without hesitation :D As far as the pellet I use...I choose the Crosman pointed 14.3 because its the standard testing weight in .22 and it has less resistance through the barrel...compared to the hollow point which always reads slower fps even though its the same weight....more drag???. Not sure...but it does come out about 10 fps slower....Yes Phantoms and indeed most Crosman guns lend themselves well to a good tuning...which is part of the fun....at least for me...thank you for the thumbs up... :D
