TSD type 96 coke (pepsi) can test

[Sim123456]

Redwolf

Redwolf



ONE SIDE
(BB remains in can after penetrating one side) 290 to 310 fps All figures are approximated based on tests with an 0.2g BB. Varying weight of BB may alter results as the above FPS values only apply for 0.2g BBs. Using 0.25g BBs will sometimes allow you to penetrate a surface even at the lower FPS rate. All FPS measurements chrono'd with a Combro cb-625. The range of FPS above accounts for minor structural differences between cans which can require a little more FPS to make the mark.

BOTH SIDES
(BB makes it straight through and exits on the other side) 350 to 370fps
BOTTOM (CENTRAL) 420 to 450fps
BOTTOM (EDGE) 450 to 480fps
TOP (EDGE) 480 to 510fps
TOP (CENTRAL) 520 to 540fps

This is a for fun purpose since in no way replace a chrono, but still nice for a 300$ springer

I've tried the can test often, and I can say it's not very reliable. I had started to try to do a chrony vs can test to try to revise the Redwolf numbers for cans used here in Canada, but results were too inconsistent. I found that in some cases, a gun would shoot right through both sides of one can, and barely make it through the side of another. It's really not reliable.

My CA M15 currently shoots 385 fps, and can easily punch through the centre of the bottom of any can. My JG 416 currently shoots 425 and can easily punch through the edge of the top of some cans, but not others.

So while it's a fun test, it's not very reliable.

Of course it make sens since I don't think that a Maruzen type 96 clonde would pup out 540 fps out of the box.

But when I tried with my KJW M9 last year, with an high flow valve and stiffer srpings, I was exactly at the 350-370. I could pass through both sides of the can at gun point but not in the bottom central.

But maybe the thickness is never even from a can batch to an other another anyway

That's what I concluded from my minimal testing some months back. I really wanted to give a reliable "poor man's chrony" based on cans we have here in Canada, rather than cans used in Asia, but couldn't get any consistent results. I'm chalking it up to inconsistency in thickness / strength of our cans, as I can confirm that the muzzle velocity of my guns are fairly consistent within 10-15 fps...

We found a similar thing. We didn't do too much comparisons between brands, but we compared "poor man's chronie" results with an actual chronie, and it was reliable to within about 50-60fps, which is pretty usless.

Solution: Get a real chrony!

Good idea, send one to me I'll be very pleased!

Madbull one from AirsoftParts.ca - $100
It's a good investment, especially if you work on guns.

Solution : Get a real chrony = Fail

My chrony broke after about 1 months and shot less than about 50 rounds through it.

So, what's the FPS benchmark for shooting through the metal on a chrony?

I'm actually impressed yoou got 50 rounds through it before it failed.

What kind of chrony? And you must have been treating it like crap.

[KND]

Come on ! dude, I treat my chrony than my love. It always in box all time and also has been clean after each use. huh ! how can i treat more than this ? it's madbull chronoy.
