I dont doubt a FMJ 223 round would go through both lungs of a moose or elk but i dont know about the shoulders. I know that a 22-250 loaded with 70 grain barnes bullets will almost penetrate a moose length-wise though.

The problem with the FMJs is they have a tendency to tumble as soon as they hit something.

If it wasn't 20 some below right now I have an old Ford 360 engine sitting in the junk pile. I could go shoot it from whatever distance and give the results. Wouldn't have a grill, radiator, fenders, bumper, inner fenders, etc to slow it down.

What brand was the engine block? Toyota, Dodge, ???????

i believe it was a chev. cavalier.. but i'm not certain.. all i remember is they told us if we ever have to hide behind a car, hide behind the wheel AND the engine block.. thats why cops angle cars on traffic stops.. maybe it didn't go all the way through the block length wise, but i know it went through part of it.. we put real long metal rods through the car to show the path of the fmj bullet.. yeah, it's a small bullet with a helluva velocity.. i know it's not ethical and i wouldn't do it, just wondering if two .22 sized holes in the front two shoulders of an elk/moose would bring it down...

.223 Remington will not drop an elk or moose with a shoulder shot, end of discussion.

your from matador, texas.. how many elk do you have down there??

I may be from Matador,Texas, but I know what a bullet can and can't do to game, something you may want to experience some time.As for your personal attack, its uncalled for.

The lack of knowledge you have in hunting, and balllistics, is laughable. Actually do some hunting, before you come and blow my horn.

I'm sorry but I agree with pighunter I've seen the size of both moose and elk there is no way a .223 can drop one of eather with a shoulder shot it doesnt have the stopping power. looking at the characteristics of the round all it does is pierce through it doesnt dump enough energy to knock it down. that's plain and simple. you have to use at least a 7mm in order to drop eather of them. Personaly I would use a .50BMG on moose simply because of their tempers but I know that is over kill. I would honestly use my M1 Garand hunting both those animals.

the 270 is a proven round to take Elk and Moose.
Now I want to go shoot my old Ford 302 block with my AR.(5.56)
