450 FPS is more than adequate for a target pistol and the 33 FPS lost will not be noticeable at all, but the other effects were.
Power is not everything and sometimes less is more

Interesting results though and thanks for sharing them

BTW what differences were there, if any, on cocking effort?
Cocking effort is perhaps slightly increased. Final thock at end of stroke marginally increased with the Delrin Top hat versus stock set up but spring twang and vibration through grip totally eliminated.
Having learnt to use a tight grip with the 53.....quite unlike other springers, incl. rifles, one is better able to control the accuracy and slight extra increase of the top hat in steel (extra weight and power) made little or no difference to me personally.
I may offer a Delrin Top hat for anyone who is interested that has purchased the kit.
I will extensively test further to find out just how much accuracy improvement can be had by swapping out the weighted top hat but in complete honesty im feeling little difference.
Ill post again after anothers days testing.
