Does an M14 really turn cover into concealment? Part 6: 50m concrete

[chopinbloc]

M1A vs. AR at 50 meters against concrete blocks. The M1A will be firing M80 FMJ while the AR is firing M855. In previous tests we looked at the effects of only a single round each and at very close range. This time we will put the AR against the M1A head to head, with as many rounds fired as are necessary to reduce the target to pieces too small to reasonably hit. Both shooters will attempt to fire their rifle as quickly as they can to make accurate hits. This is an informal test, of course, but we'll be looking to see which rifle can reduce the concrete "cover" to concealment more quickly and which can do it with less rounds fired as well as which uses a greater percentage of its available ammunition. Because 7.62x51mm weighs twice as much as 5.56x45mm, the M1A gets one 20 round magazine and the AR gets two. Which rifle do you think will win and on what grounds? Will the heavier recoil of the M1A allow the AR to finish more quickly? Will the greater mass of the .30 caliber crush the block with fewer rounds fired?


Target is a two gallon bucket filled with Quickrete with aggregate.

That was a fun experiment, 44mag does well on these types of tests too. Wonder how the Garand would perform with M2 ball?

Always thought that was the 45-70

"Does an M14 really turn cover into concealment?"

No, that is why we still have the Ma Duece.........

But on shipboard security alerts, my position was to take my M-14 up to the top of the Mack (combined mast & stacks) platform. I commanded the entire superstructure and weather deck. I was GOD, in that position. With most of the above deck structure made of aluminum, there was precious little "cover" that I could not shoot through, if needed.
Another reason I liked the M-14 on that detail..... The .45 pistol got 7 rounds. The Rem 870 12 gauge got 12 rounds. The M-14 guy got three 20 round magazines.
