I am anticipating participating in my first long range shoot in late April. The distances will vary from 100 to 1000 yards. The plan is to have the shooters shoot prone off a bag or bipod. This appears to be an informal shoot compared to some matches, as it was spawned from a forum. I plan on bringing my .300RUM Sendero and shooting a 220gr SMK. I am a bit worried about my scope though. I have a Leupold Vari-X III 6.50-20x40AO. I am assuming I will have to buy some Burris Signature rings, and that should give me 25MOA alone. I was wondering if this setup will be enough to compete. I have also replaced the trigger with a rifle basix and have it in the 1lb range. Hopefully this will be enough. Any tips you can provide me to better train for this event would really be appreciated. I plan to start imediatly, shooting at 500 and moving out farther. The shoot is in Mid April so I hope I have enough time.
