A friend is looking for a reamer for what he called a .20
Hornet. I told him that I thought it was called .20 Squirrel.
Anyone know about this? If I'm right, then is the .20
Squirrel based on the Hornet, or the K-Hornet? Does anyone
know where he could get a chamber reamer?

Yes. Dave Kiff at Precision Pacific grinds this reamer. You can get it with either a 30 or 40 degree shoulder. Greg Tannel [Gre-Tan Rifles] has a 40 degree reamer and builds rifles in this unique chambering [he built one for me on a Kimber Model 82, previously a .22 Hornet]. Greg's number is [970] 353-6176. I am sorry, I don't have Dave Kiff's number.
You can probably find it on the web, or in the following magazines: Precision Shooting, Varmint Hunter or Small Caliber News.

Since we are talking wildcat anyway, why not go for the 20 K Hornet?
