A buddy came down and we took my M1A NM JAE-100 down to the huntclub, into one of the larger fields for some shooting. I'm short on cash right now, so I was shooting a Prostaff 3-9x40 Nikoplex reticle scope (4/4 MOA subtended). The day prior I had set it up to shoot 12" high at 100 yds. I was shooting about 1.20 MOA.

We set up some large diameter balloons and a 10" AR500 steel plate on a rise at the far end and start wed working our way back. After a few flubs (when I tried to memorize my dope rather than reading it) I consulted my cheat sheet and started on steel at 300 with a 7 MOA hold-under. We then started moving, back to 450, with a 2 MOA hold-under. The next shootable position was at 550.

With our 496 yard zero, we finally starting applying old over, with 2 MOA at 550. We wrapped up the day at 630 yards and what I'm estimating to be 7 MOA of hold-over since we were well into the lower post. We also applied 2.5 MOA of left wind hold-off. The hold was complicated enough to merit a sketch when I handed the rifle over to my buddy. After checking my notes, he was also able to score several hits on the 10" steel. This is his second time out. He doesn't own any guns himself.

Remember, we're shooting a duplex.

It was a good weekend out. Despite lacking a few bills to rub together, my humble Prostaff was very serviceable while I wait to buy something nicer.

A note on the scope. I have found the Nikon Prostaff to be very, very reliable in holding zero. The optical quality itself is a little better than par at the price point, but I believe the low-light performance is lacking. I have found the 1/4" adjustments to be more in the neighborhood of 1/3" and 1/2". The scope is best adjusted with a two-headed mallet after each minor dial correction so that the erector settles in. Once zeroed, it is zeroed. That's why I like it.

On the M1A NM, my favorite aspect of this particular rifle is the negligible affect of barrel heat on a string of shots. I literally cannot notice an appreciable change. I once owned a bull-barreled Remington 700 which would string very noticeably and ruin good groups. It made shooting less fun. This M1A has practically eliminated that concern while dramatically increasing fire power.

Sounds like a great day. I've never been taught to shoot rifles properly and the only longish range stuff I do is in 3 gun. I shot my HRA service grade in a 3 gun last week and I was able to clean the LR steel course from a wood brace. Longest flasher was at 400 yards.
