Well Nobade one upped me last week by showing up with his new store bought cross sticks at our local lever action silhouette match and afterwards managed some decent long range gong shots with his 2 Sharp's rifles. One thing was immediately apparent was the spike layout left a lot to be desired on our range. They wouldn't and couldn't be driven into the soil at our range. This part of the world has about 3 types of soil: sand, lava rock and caliche which often can make one believe it is granite!
Anyway here is my attempt to improve on his sticks. I would definitely do a few things differently if I were to start over, like case harden the spikes and braze or weld on the angle shields on the lower legs plus getting a forstner drill bit or at least a spade drill bit of the right size as metal twist drills like to grab and splinter the wood.
