I was searching through some various websites looking for different kinds of targets for longer range shooting, especially for sighting in, and stumbled across a site I thought was pretty decent. You can choose the size of the target you want to print (depending on your printer's capabilities), what colours to make the bull and rings, whether or not to insert a grid, even what spacing you want for grid and/or rings, and whether to number them.
I get a little tired of shelling out multiple $$$ for small packages of 4 or 5 targets the same size or smaller, and my shooting buddy has a 11" X 17" ledger-paper-sized printer, so I did up my own in that size. And for sighting in, I wanted something slightly larger than the small 8.5 X 11 at longer ranges, with grid lines to make it easy to dial in the scope. Colour printer would be a bonus.
Just posting for anybody who may be interested.

Just set up the parameters you want (paper size, bull size, rings or not, colours, grid, etc.), hit "build your target", then "download the .pdf", save the .pdf and print - with the proper size paper in your tray.
Worked for me, and came out great.
