I also never understood it, makes zero sense to me. I have a spinner target and three AR500 gongs (2", and two 4") which I really want to just use at 100yd. For the time being, I just use blocks of wood hanging off my target stand and golf balls at 100. Not that a single person has ever actually followed all the rules there, but I do attempt to even as I watch everyone around me ignore em.
You guys should get your sh!t together at 300 over the winter to prepare for the first 600 prone match at Cumberland in the spring.
Opening weekend in Millville is April 4/5, 2020. Saturday is 200/300/600 cross-the-course. Sunday is 600 mid-range prone (sling) and F-class (rest)
Come out to SJSC (Winslow Twp, Camden County) for 300 prone Frozen Nutz to practice. Matches are Sunday 12/1/19, 1/5/20, 2/2/20, and 3/1/20. Since we are limited to 3 relays (it starts to get dark) you MUST pre-register during the week preceding the match.
Easy to do - just PM me here - I'm the guy that squads the match.
I am chiming in late but anyway..... Some of the answers are jumping out a bit. You can't just gear up and hit the 1000 range.
These are the basics for me. Get a good zero at 100. Get a ballistics chart for the ammo you shot. Then shoot 300. Then try an F Class at 600. Then work on 1000.
You need a good scope with enough clicks to get to 1000. This gets expensive.
I have done 600 so far and that was not a big deal. Except my scope was good only to about 850 yards. I even had a 10 moa biased rail which was not enough. The new scope cost about $550. (List $700.)
You can find 300 at South Jersey RPC and Central Jersey RPC. F Class 600 at Cumberland, Millville, NJ.
I will probably take a spring/summer trip to PA or WV to shoot 1000.
That is all.
