What did the minimum FPS need to kill squirrels effectively at 25 yard. Currently shooting Crosman 2240 at an average of 474.

The answer to your question is completely dependent on projectile weight as well as speed and most of all shot placement!

There are a lot of variables at play here. 500 Feet Per Second on a .177 is not the same as FPS on a .25. Much more power being delivered from the .25 at the same speed. However, the.177 may have more penetration. Then there’s shot placement. Distance to quarry, Etc.

If you’re asking if that gun will take squirrels, the answer is yes with a properly placed shot.
Before I got my big toy I went to Wally World and got a 1322 (about a 6FPE gun like yours) to combat my squirrel problem and found the only effective shot was to the temple.
I once took a direct facing shot that I thought I missed after he bolted up the tree. About a minute later I found out it bounced off the squirrel’s skull which caused him to loose balance and fall 40ft onto my driveway which killed him.
I think if your need to eliminate squirrels you will be extremely handicapped using that gun.
Something like a cheap springer that can do about 16FPE will probally serve you much better.

Hi a crossman 2240 is a 22 pistol , which can get up to 14fpe but most should be around 12fpe
so it should shoot 18 grains like 600fps , so somehow your gun is way to low unless you shooting 33 gr jsb at 454 which would be 14fpe
so to answer question , 6 fpe can kill a squirrel with a good shot placement , The main thing is if you can group 5 of 5 shots under 1/2 inch then this is the range you should shoot a squirrel , I have killed squirrels with a 12fpe gun at 65 yards , but the gun is lazer accurate ,
shot placement is everything , with low power like this you have to be spot on , when you did chrono what weight you using ???? if it is really 454fps was your CO2 FULL?

I used the Chrono today and was using .22 Crosman with no weight mentioned. I will try tomorrow with Polymag 16 gr...it will shoot 1/2 inch at 25 yards. I typically run a FX Impact .25, but that gun is in the shop ...and the squirrels are taking advantage of the down time . Here is a pic of the gun

It will, but go for the vitals. Head shots are great if you can get it through the skull, but with your power level shots past 20 yds can have troubles.
