Shot GB's over chronograph today, 500 fps. I was a little surprised.
Put some paint on yesterdays creation.
My 'little brother' popped off a few rounds.

good job,wish i had the money for a chrono

I borrowed it from a guy that loads his own pistol ammo.
New ones I think are $85. ? Try to get together with some other shooters.
Maybe meet once a month at a safe place to shoot?
Once you have speed figuring distance would be easy.

but im 13 lol

I hate to say it, paying work?
Hey, your way ahead of me when I was 13!!

lol well i do feel better since most 13 year old kid's parents dont let them make potato guns, my parents support me

Spudgunning is (almost) always better than doing drugs.

Don't do any thing crazy with those guns to screw up that trust.
All we have is our word.

well my relatives thinks it great, better then those people that lay on the comp all day and play games.

Spudgunning is (almost) always better than doing drugs.

Yes, but if he had a job, he could afford both

Pizlo Every thing in moderation. Don't go crazy over either one

George Carlin said "I never had a problem with drugs until I could afford all I wanted" He is in recovery now. You know,AA.

Is that a 1.5 inch QEV?

Very nice, at that velocity you have a muzzle energy of around 380 ft/lbs - much more than a '38 special revolver round and three times the energy of a typical 22LR rimfire round

I just bought this chrony new for less than 80 bucks, it's an affordable bit of kit and very useful for advanced spud development.
