This is not true. 55 grain pills work just fine in 1:7 twist guns. I wouldn't venture much below that but certainly 55 grainers are A-OK.

Additionally, I wouldn't limit your choices within 300 yards. Mil-spec (I know, not the greatest threshold, but a threshold nonetheless) states M4 carbine's effective point target range is 500m...with 55 grain ball.

What you say about wind drift is accurate however. Heavier bullet = less effected by wind. Again, there's always a trade off. Heavier bullet = faster drop.

Keep in mind when reading this statement that "effective" with an M4 is minute-of-bad-guy. Someone looking for MOA accuracy at 500 with 55g ain't gonna get it...

Agreed. 55's would get thrown around, hence my original suggestion of the 75gr SMK's. OP made no mention of shooting for tiny groups though. But frankly, getting MOA accuracy out of any .223/5.56mm at 500 is pretty tough.

One man's ceiling is another man's floor.

If you're plinking, 55's are fine in 1/7. If you're looking to shoot the smallest groups your rifle can produce, 55's suck bad in a 1/7. The 55gn round is just not long enough to perform well in the 1/7.

Which is why I am looking for suggestions on other Weight/Brand Bullets. I have some 62gr m855's that I will break out once the weather gets better but looking for others as well.. I am not expecting Sub MOA

As I stated in my post 300 ish yds you reall don't need the 75-77 gr stuff 60 -69 gr will hold its own just as well but if you want any form of accuracy just don't waist time with fmj bullets . A few good ones I would suggest would be the hornady amax , 65 gr serria game king . About any of the 68-69 gr match bullets your gun will decide which one it likes best .
