between my brother and i one of my favorite rifles for ground squirrels is my Marlin Guide Gun in 45-70.....first shot at one i had 405 hard casts loaded and held on dirt....the bullet went through 6 inches or so of fluffed up dirt on the near side, couple inches of gopher, another 6 inches of fluffed up dirt on the far side, put a 5 foot divot in the ground, hit a chunk of sandstone and cracked it but finally stopped it.....we had been shooting the critters for high talley and upon seeing the damage promptly declared me a cheater and he will get to shoot it for the rest of the trip and i was stuck with the 10-22
