I happen to have a Tack Driver.
Mine is a Nosler M48 Handgun, which is a single shot bolt action. So far I have ran a steady diet of Sierra 77 SMK bullets through it. I will probably try some Hornady 75 grain ELD-M bullets next. I have lots of Berger 80's as well as Hornady 80 grain A-Max bullets on hand for my 600 F Class 223. I should try a few of the 80's as well.
I have a Weaver 8-32 Classic Extreme Scope on it, that will Dial. I also have a Log Book with a Drop Chart in 25 yard increments. I can shoot little groups on steel all the way to 600 yards with no issues at all.
This gun came out of an estate unfired. It was custom ordered with the Barrel and Action Bright White, and the Stock Bright Orange. It came with lots of goodies. Fluted Barrel, Muzzle Brake, and a Fancy Bolt. Before bidding on it, I checked with Hunts Long Range to be sure that they could refinish it in a color combination more to my liking. Black Barrel & Action, and a Camo Stock. The best that I remember I ended up with $1500 in it after the refinish work. It ended up looking so good that I had my 6.5CM Nosler M48 Stock refinished in the same camo pattern.
If I had a choice, I would have picked a different chambering for it. HOWEVER the Nosler M48 Custom Handgun's only .224 chambering is in 22 Nosler. I liked the 22 Nosler much better after shooting it.
I would lay in a supply of Brass for it, so that you can keep it running for years. I would not bet money that brass will be made for it in 10 or so years.
