A friend and I often fire a 3/8 inch steel plate he has set up in his back yard. Most of the time, using Wolf ammunition (manufactured at the Tula Cartridge Works), it won't penetrate through. However, Norinco and other brands of military ammo - which aren't hollow pointed and subject to the increased expansion of being hollow pointed - often are able to penetrate it.
ak74 don't penetrate walls.this happens if only the wall is weak,wearing out,old or not a real wall.walls are usually hard and thick.the bullet is capable of boring holes in the wall not making it porous just like the ak47.
Oxygen can not penetrate to great depth.
forged steel or sheet metal with plywood
steel
Red wavelengths are unable to penetrate to that depth as they are absorbed. Green wavelengths penetrate deep and therefore blood appears green!
Only to a very small depth.
the bar because it shoots a 30.6 and an ak47 shoots a 7.62x39 the bar has a bigger bullet the ak47 probbably has better penetration though because it often uses steel core full metal jacket ammo
the russian made "milled steel" ones are the best. any other milled steel AK-47 (not stamped steel) can be one of the best in its kind
The frost depth refers to how deeply frost can penetrate into the ground. In Martinsville, Virginia, the frost depth is around 18 inches deep.
Cannot give you one simple answer. It will depend on the type of steel, the angle of impact, the distance to the plate, and what type of cartridge the AK47 is firing. They DO make an armor piercing cartridge, and it goes through more armor than a regular ball cartridge.
Sunlight can penetrate into the ocean to an average depth of about 200 meters (656 feet). This depth can vary depending on factors such as water clarity, time of day, and geographic location. Beyond this depth, the ocean becomes progressively darker as less sunlight is able to penetrate.
There is no "usable" light agter 200 meters...
