If we're arguing about that, I'm 20/10.
And yes - I once spotted one of my Nan's dogs (a little smaller than a toddler) in the ferns a quarter mile away across a Welsh mountain side.
Anyway, my experience is that most toddlers are not out crawling in the grass unattended where spudgunners might be firing.
do you know of a spud gun with accuracy of less than 1 MOA? you may intend to hit something 500 yards away, but YOU WON'T!
Not yet, but I'm working towards it.
Besides, as MrCrowley says, that just defeats your point - if a person is out there, given the inaccuracy of spudguns, the spud could land in an circle nearly 50 or 100 yards across. The chance of hitting a person who's within that area is slim to say the least.
my first spud gun generates 1400 lb/ft of energy with a potato, a head shot would cause massive trauma and death, a body shot would break a few bones, adding a little "extra" to the potato would cause more "damage".
You still haven't broken out the chronograph I see. Really, 1400 ft/lbs from that combustion of yours isn't happening.
No matter what prediction method I try (HGDT, pressure/volume calculations, EVBEC), I can't even get a quarter of that.
I'll admit the pressure/volume calc is only a ballpark figure, but HGDT and EVBEC are almost always within 10 or 20% at the outside.
80% error from these things is completely unheard of. I'm sorry, but you need to use a proper chrony - guessing numbers from a 30 frame/second video will not give you accurate results.
I assure you, when you get the chrony out, the numbers will almost certainly be more like 250 to 300 ft-lbs, which is what all other combustions that size would be generating.
Besides, that's at the muzzle. 500 yards away, regardless of how fast it was in the first place, it's unlikely to have more than a couple of dozen ft-lbs left - and over such a large area with a soft projectile like a spud, penetration of the skin or lethality is exceptionally unlikely.
Spuds and golf balls are not ballistically efficent.
in the last week i've seen a few others who haven't read the rules, and even a few more who have yet to have been reprimanded.
You have no idea if that's true. Moderators do most of their work by PM.
I broke a rule once here ("inciting mass argument by mentioning religion" - or something like that)- I did know about it, but I'd forgotten in the act of posting. That still didn't excuse me.
Anyway, myself, I've largely given up on distance shots. When the spud is leaving the muzzle at 600 fps or so, it's hard to follow it in the air which makes it largely pointless. That said, I did have fun launching glow sticks across my "uncle's" field at night.
And before you rant at me for firing at night (with next to no visibility) - it's private property, and the only people with permission to be on it were me, or one of the people behind me, so any daft apeths (or muppets if you're not in tune with semi-archaic Lancastrian slang) that might happen to be trespassing downrange...
... Oh, look, incoming instant karma.
