There are 1000 yd matches at Camp Perry every year in August. The cheapest way is in Service Rifle. A $500 CMP Garand will get you started. You need a shooting mat, spotting scope,Some good match ammo,& eye & ear protection. You can load 168 HPBT Match-kings by Sierra in 30-06 cases with 46gr. of IMR 4895 & be ready to go.
Oh yeah,a surplus Marine Corp Shooting Jacket ($50) will be a big help.
Bolt guns for this match are much, much higher. And good optics are $500 minimum for the rifle. Peep sights will be cheaper & they are easier to use. None of these are in the same class. Scoped rifles don't compete against Peep sights. And Service rifles are also in a class by themselves.
Holler back & give a little more detail about just what you want to try & we'll try to answer you with some decent info.
