hey /k/, what's this from?

>>32289564
russian 23mm i think probably.

>>32289564
Read the markings printed on it

>>32289564
looks like a 30mm, any headstamp or writing on the side near the bottom?

I could be wrong but I think it's a buttplug

well then get the measurin tape out. looks like a 30mm gau-8 shell, wrong neck for 25mm bushmaster. the paint implies american auto cannon.

>>32289713
Shaping is the exact same as my US 20mm. So I would support >>32289826 looks US, and they would keep a similar design.

Depending on the size of your wankingtool, I'm gonna guess 25mm Bushmaster (25 x 137mm) at this stage

It looks what you have here is a US 30mm round from something like an A-10. Here is a photo of the one I have for comparison.

OP would be in a world of pain if he did that without the projectile. Fucking rough edges on that shit.

if this is a 30mm its from an a10 as the apache casing doesnt taper at the end like that

/k/ how hard would it be to shove a 20mm up my ass?

I don't know where it's from but I know where it's going

>>32293067

There was a thread on /k/ a while ago where someone did that

Do 20mm and 30mm rounds used in the GAU-8 or whatever use regular rifle powder as a charge, or some other sort of propellant? I would imagine they have their own thing, but at the same time you could really cram a shitload of rifle powder into those cases.

From my expertise, I can confirm that this is actually your mom's dildo

>>32293948
double-base propellant, they were working on something better irc.

>>32291733
Eod fag is correct. Bushmaster 25. Or Bradley's shoot those. The 30mm from the a10 is distinctively larger

why not equip bradleys with 30mm chainguns and have ammo commonality?

i disagree 25mm is shorter unless op has an unusually small hand and look at the shoulder.
