If you mean a .22 Long Rifle cartridge, see the link at the bottom of this page.
22 BR, 6mmBR, 6.5BR, 7mmBR and 30 BR are all a group of cartridges made by cutting a 308 Win down to 1.5 in and necking to the desired caliber to shoot in Bench Rest competition.So it looks like a short 308 Winchester
A large revolver
Like a Colt 25 auto
much like a 38 special cartridge except a little shorter..
You will have to google it. No way to post pictures here.
it looks exactly like a vietnam era m16 in .22 caliber
Well, 22-250 refers to the caliber of the cartridge it fires. The rifle itself could have been made by several different companies. Most will be a bolt action rifle, most will have a telescope. It could be blued steel or stainless steel, it could have a wooden stock or synthetic material.
You could look around online on websites like Amazon.com or ebay.com to buy a cheap ink cartridge. I would go to amazon.com and go look for used ink cartridges for the cheapest prices.
Pretty much the same as any other revolver or semi-auto.
Need to know iif its a revolver or semi-automatic and the caliber.
See the link at the bottom of this page for a good article on rimfires, with photos.
