## .625 range

From what I was taught in physics at Tulsa University, the maximum elevation for maximum range - in theory (no air drag, etc) is 45 degrees.  Anything more and the projectile will arc up higher but fall short of the 45 degree range.  Anything less and the projectile hits the ground short of the 45 degree range before expending all it's available energy.

@ T54  I wait for the wind flags to drop then try to get in a shot or two 250-275 IS a long ways even with a tail wind

@ C50  Next time i get out for more test i'll elevate the tube 3 deg. at a time and record the results I was thinking that 33-35 would give longest shots

Yup - 45 degree angle gives the maximum range.  Here's a good illustration.....

Thanks Thunker  that saves me some air lol  26 degrees is what was needed to hit the back stop at 100 yrds
Backstop is mounted about 4 ft. high.  wanted to shoot at 200 but got goofing around and lost the day

Welp, that's all theory - no air resistance, etc, etc...  In my 56 years I've learned that what works in reality isn't necessarily what is best theoretically.  But at least it gives us a place to start.
Whatever gives the best results in the field is what counts!

just when practicing i have gotten up to 45 feet while staying accurate.

i have shot mine at a lot and i have taking shots upward of 50 yds + mind you i can't say i hit a dime that far away everyshot but a 9in pie plate is not a problem there.
