I was in another forum where this came up.
I got told (of course) that the AR15/M16 is a piece of shit that never works (So I wonder what I'm doing wrong, as mine have all been exceptional).
Then I got told the M14 is better because .308 turns "cover" (by which they meant "car doors," and claimed that sandbags were "unrealistic" cover...was this guy EVER in the military???) into "concealment."
Then that a Garand operator can reload without taking the firing hand off the stock, while of course anyone with an AR needs both hands to reload. (I'm just quoting these idiots, you understand.)
Now, the Garand is a fine rifle and I've shot several. It's also a relic at this point. The M14 had the ignominious distinction of being the shortest lived small arm in the US inventory, because it wasn't signficantly better than a Garand and cost 3X as much.
Anyway, I issued a challenge to test all three weapons with the same conditions.
At which point I got stupid offers like "dump a can of creamed corn in the open action" and "Fill it with sand."
I'm proposing burying in sand, then shooting; sticking in a sandblast cabinet and swirling dust around (not direct blasting) and then shooting, and then dunking in mucky water and then shooting.
My personal experience with the AR (22 years) tells me it will handle this just fine. It's also fairly realistic for military use (20 years experience). I'm more than willing to volunteer my AR. I need to find an M1A and a Garand that work well clean to submit to dirt. I plan to document this in detail, with records and photos.
Anyone want to help with ammo, weapons or shooting tests?
