Hi,
I'm planning to shoot my first NRA service rifle match tomorrow. It will be held on a range with 200 yards maximum distance, so reduced targets will be used, I assume. First I will describe the equipment I have:
I have a Compass Lake Engineering AR-15 A4 service rifle upper with a douglas 1:7 twist chrome moly barrel and 1/4 MOA rear sight. The lower is an LRB with a Geiselle service rifle trigger and A2 stock. I have a turner sling but can't figure out how to use it so I will use a GI nylon web sling.
I'm planning to use black hills 77gr BTHP match ammunition. I have zero'd the rifle at 100 yards with a "center hold" using this ammunition. It is shooting less than 1 MOA from prone.
I have 4 30 round Magpul PMags. I am a big & fat (6ft 280 lbs) person so the 30 round magazines do not interfere with my prone position.
I have a Konus 30-60x spotting scope with a ray vin "eclipse" stand. I have a shooting glove. I have a shooting jacket but I probably won't wear it because it doesn't fit. I have a folding chair, a notebook, and a pen.
I have a high power style shooting mat.
My questions:
What is the course of fire, and how can I calculate my come ups for a "6 oclock hold" on each stage beforehand?
I have chrono'd the ammunition through my rifle and the black hills using the 77gr SMK bullet is giving me right at 2700 fps.
Thanks in advance, I appreciate any links or knowledge you can share.
