I have been digging bullets at this spot for a while.. today I got a good signal with my etrac ,a strong 17-40 fe co .. I dug down about 3 inches and hit a rock about the size and shape of a big watermelon .. the target is dead center of the rock.. I tried for about 15 minutes to get the rock up but it won't budge.. I can't imagine how anything got under it.. what is 17-40 on a chart? Couldn't find it on the ones I looked up.. going back with a grubbing hoe and trenching shovel next time..
 
The closes that I could find on the reading comes from Andy Sabisch book page 138 was 18 and 37 being an CW artillery shell
