What do you use to shoot in?

Back Stops can be made cheaply enough, but you will have to have either some sand or soil to stop the bullets.

you can make a good backstop out of a large wooden box, wood stacks, or create a burm. Muzzleloader bullets are easy to stop, but they are bullets and 1000 yards is no mean feat for a misplaced shot.

A simple backstop is a box made from logs or 4X6's closed on three sides and built up about 1/3 to 1/2 height in front facing you. Fill with dirt and use target frame stuck into the dirt or affixed to the front of the box. The dirt or sand will settle some over time, but usually won't spill out of the box . This still will cost money, but will last a lifetime of the wood (5-10 years) and cost around here about $500 to $700 to purchase materials.

If you have trees, then its yer labor cost to cut, trim, and stack, log together. The two I have used are about 8 feet deep by 10 feet wide and stop 22's and muzzleloaders quite ok.

I don't know about anything heavier than a 45/70 into this, but you can use your judgement.
