the Glock 22 (.40 cal) and Glock 27 (.40 cal) i believe they get those at their departure from the academy
7.62 mm (or 30 caliber) and 5.56 mm (or 223 caliber) are common rifle cartridges. Pistols, machine guns, and artillery will of course be different from these.
you can not use metal bbs in airsoft guns at all. they are not compatible because they are both built differently.
With VERY FEW exceptions all BB guns use the same size BB .177 Caliber.
7.65mm is .32 caliber. I own one of these guns and love it.
4.5 cal (9mm) like most guns
any single or double action semi-automatic pistol listed as a 40 caliber pistol...............
The police station or use directory enquiries.
No. most guns are .68 caliber, however there are some .50 and .43 caliber markers and pistols.
They used .58 caliber minie bullet's, lead slugs, and Thud Cannon's.
The highest caliber machine gun in standard use is the .50 Cal. Gatling guns are used in 20mm caliber. XXXXXXXXX Russia and China use a heavy machine gun larger than the .50 cal BMG- it is the Vladmirov KDV (for the Russians), in caliber 14.5mm x 115.
There WERE BB guns that used an .11 caliber BB, instead of the common .177 caliber, but unsure if Sears may have sold some of them. A standard BB will not fit in the barrel of the .11 caliber guns. Unfortunately, do not know of any company still making the miniatures. It is possible that individual pellets of birdshot MAY be usable- #6 is about .12 caliber, so would be smaller than that. MOST Sears BB guns used regular BBs.
I shoot the pests at my house w/ pellet guns, so no one know. But good guns for rodents/ gophers are 22 rifles, and small caliber guns. I advise pellet guns because they aren't loud but can kill rodents easily.
