Well since marines hit at 500m with iron sights no big deal. 600 with an acog is childs play.
personally used an acog out to 900. good enough to be minute of vehicle with an M4
Well Jesus Christ, Marry, Joseph and all the carpenters...I don’t know what it is about this forum lately but it seems to have been struck with a blight of ignorance brought forth by an influx of un-informed characters that seem to desire to participate for no other reason than to present braggadocio claims if their marksmanship.
Now don’t get me wrong, I love to spin a tale from time to time but I do so with a purpose and benefits to others.
Fact: Marines do shoot to 500m during table 1, with irons (and now also with RCOs)
Fact: that target is (unless it’s changed) a full 20”x40” E-type...with 6’x6’ backer. All impacts on the board are marked with spotting disk to give the shoot visual add.
Fact: only 37-49% of Marines will qualify expert, which can be achieved with a minimum hit rate of 50% at 500m...on a full E-type. Most Marines will qualify as sharp shooter or marksman which can be done with 0% hits at 500m (though unlikely)
Fact: these scores are achieved after two weeks of professional instruction/indoctrination immediately proceeding qualification for scoring.
So returning to the OP situation:
“...varying ranges out to 600m with 24 inch silhouette targets. Going to use a 16 inch 6920 and 4x32 ACOG. Going to shoot m193.”
Here we have a situation where the distances are likely to be unknown, with targets almost half the size, and likely no spotting disk to add in correcting misses and splash even with the heavy projectiles is likely to be difficult.
While it certainly not an impossible task for an expert shooter, and the use of better rifles and ammunition greatly increase hit probability, it still isn’t “child’s play” especially when asked to deliver on command.
This regurgitate of things like “wElL tHe mArInes...AnD iRoN sIGhts!” is generally unproductive and misleading.
