First 600 YD experience

I took the new girl (see M14 of the Month thread) to the range yesterday for a 600 yard Prone practice session. I have shot a few 500 yard Prone matches, but my first 600 would have been this weekend( another story for another time...). We were paired up, and my shooting partner said he would prefer pit duty and coffee first,if I didn't mind shooting first. 70 degrees and ZERO wind...nope, I don't mind at all!

Sent 15 rounds down range, chasing the spotter vertically. I got a bit frustrated,because 1 min. shouldn't make THAT big of a change....

Rotated to the pits. After marking a couple of shots, I noticed the target face was for F class! Figured out the 8s and 9s I was shooting were not so bad, and figured out why 1 min made such a change! Also figured out that I should relax and ENJOY our sport, instead of getting wound up about it.

Preferred method would be to shoot a group of say 3-4 and determine center of that group, not an individual bullet hole. If group is low and in the left corner of the target face for example, somewhat outside the bulls eye, and realizing that 1 moa @ 600yds. is equivalent to 6" I would come over to the right some 2-3 minutes(12-18") and up 2-3 minutes and should put you somewhere in the black and fine tune it from there. Just a suggestion. I do not shoot F class but I understand that the bulls eye is somewhat smaller than regulation NRA HP/Long Range targets but that should not be a handicap for F class is shooting from a supported fire position, bag, bi pod, etc, more the rifle than the shooter in such matches.

Thanks from AzCasper

That F-class rings are almost half the size of the NRA rings. NRA X-ring is 1MOA or 6" diameter, 10-ring is 2 MOA or 12" diameter. Nice job if you're holding within the 8 ring for most of your shots. Heck, my "wobble" has to be at least 2 MOA.

Thanks from dwight55 and AzCasper

Yep, those F-class scoring rings are pretty intimidating to open sight shooters!

As for vertical stringing, try really focusing on the front sight during the shot process. I have to REALLY concentrate on doing this or I get vertical dispersion.

Sounds like you had a fun day.

congrats on your new girl at 600 yards. My club is only a 200 yard range but next season I am going to test my Charlene at a few 600 yard matches

Shooting irons, right? Even on my best USGI/tuned sights, I don't like adjusting them unless I really have to, during a string. Probability is high that the sights won't move where I expect them to. Just not very precise.

And that is one place were the AR sights really shine!

Quick and easy way to determine the preciseness of your rear sight is find, buy, borrow magnetic base/dial indicator and determine how much each click is giving and seeing a corresponding number on the dial, so many thousands per click. Take the rack/aperture from lowest setting and to the highest setting and see if you can detect variance from click to click. You can do the same for the wind drum/clicks. If variance is obviously large and shooting in matches at long range, say 600 and beyond, time to either rebuild the sight itself or replace with new more precise parts. Will say though that the sight for a military battle rifle is one of the best out there and can be improved if needed.

Wellcome to the real lunatic fringe! There still a few shooting prone match and XTC with the 30s, and if you're hitting 8s and 9s on a F class target at 600, MR you are doing GREAT!

Thanks from AzCasper

I DO get a lot of ribbing about my "antique" rifle from the plastic gun shooters,but that just makes me love my M1A even more! Most common comment is" I'd hate to carry THAT all day in the field." My reply is" You go ahead and carry your plastic rifle, I'll COVER you from HERE!"
