A guy I shoot with has a coroplast 6'x6' target back with replaceable centers that screws to the target lifters in the pits. He can't remember where he got it other than it was a major target supplier. A google search did not locate a similar item.

Does anyone know a source for such a target?

Might want to check with these guys: http://www.usrifleteams.com/forums/

I may not understand what you are looking for, but National Target Company may well be able to supply what you are after. The actual target paper is 72" square and uses replaceable target center as in 1000yd matches. Just a thought.

The dimensions are as you mention but it is a rigid target that screws to the cloth covered wooden frames that slide into the lifters down in the target pit.

We'll be shooting on the 11th of next month and I'll take some pictures to post since he can't remember where he got it.

I'll contact National Target Company, thanks.
