Tall order WCH for someone who seriously pursued diggers for around 55 years and tree rats for about 40. I'd be surprised if the number of firearms I've used to do so numbers less than 100, with many of them bought just for that purpose, and quite a few of those wildcats for extreme ranges. For me it came down to when during my life, so what was available to hunt where I traveled to hunt and in firearms, what I'd be shooting and always at what ranges I'd be shooting them. Numbers wise the bulk harvested was easily the ground diggers, from the tiny Whitetailed Antelope GS's up to rock chucks, and everything in between. For many years a favorite was pika in the high country for their fur along with the RC's; I had my prarie dog years, but I hunted GS's all of my hunting life either spot and stock or from a stand doing ADC for landowners.
I've used thrown rocks, slingshots, slings, sanres and traps as a young boy; BB & pellet rifles/pistols; all the rimfire calibers and just about any centerfire caliber from the 14"s up in rifles and handguns/specialty handguns; small bore shotguns; small bore traditional muzzle loaders; and long bows. They were all favorite methods at the time used. A list would be long of which specific calibers were favorites, and based again on when/where.
Preferring longer ranges for the challenge means I used quite a few bigger calibers along the way in earnest, but the 17's changed everything and quickly became my favorites of all time for diggers as they came along for all except the RC's and the longest ranges. Any of the 17 wildcats, and the 17 rimfires, and they retired all my 22 caliber firearms. The 17 rimfires even replaced my smaller 17 wildcats for the bulk of the later years I still hunted GS's, and I killed truck loads of varmints and quite a few predators with them.
