Description
CCI's TNT line built its reputation on one simple idea: give varmint hunters a bullet that does its job the instant it arrives. This .17 HMR loading pushes a 17 grain jacketed hollow point out at 2550 fps, which means a flat trajectory out to typical field ranges and minimal guesswork when it comes to holdover. This particular listing is the bulk case option, packed as 2000 rounds broken down into individual boxes of 40 to 50 rounds each, so you get the case pricing without having to buy a pallet.
What Makes CCI TNT .17 HMR Tick
The TNT bullet is a thin-jacketed hollow point designed to open up fast on contact with soft targets. That rapid expansion is exactly what you want on ground squirrels, prairie dogs, and other pest species where a quick, clean result matters more than deep penetration. Combined with the .17 HMR's naturally flat arc, this load has become a go-to for guys who spend their weekends behind a varmint rifle, whether that's a bolt gun or one of the semi-auto .17 HMR platforms that have gotten more popular in recent years.
Why Buy TNT Rimfire Ammunition by the Case
Buying the 2000 round case instead of single boxes makes sense if you shoot this cartridge with any regularity. Prairie dog towns and ground squirrel colonies have a way of eating through ammo fast, and having a case in the safe means you're not stopping mid season to track down more. Every round in the case is built on the same CCI brass and primer combination that this ammunition is known for, so you're not sacrificing consistency to get the volume discount.
Behind the CCI TNT Name
CCI has been producing rimfire ammunition out of Lewiston, Idaho since the early 1950s, and the TNT bullet design traces back to the Speer side of the business. That heritage shows up in the details, tight quality control on brass dimensions and priming that keeps ignition consistent from the first round in the case to the last. For hunters who put a premium on accuracy at range without stepping up to centerfire recoil and cost, this remains one of the more proven options in the .17 HMR lineup.

Frequently Asked Questions
What is CCI TNT .17 HMR ammo best used for?
This load is built specifically for varmint hunting, think ground squirrels, prairie dogs, and similar pest species where fast expansion and a flat trajectory matter more than penetration. The 17 grain hollow point opens up quickly on impact, which limits wounded animals escaping to burrows. It's not really a small game meat hunting round since it tends to be pretty destructive on anything lighter than a squirrel-sized target.
Can I run this ammo through a semi-automatic .17 HMR rifle?
CCI recommends checking with your firearm's manufacturer before running any .17 HMR ammunition through a semi-auto action, since not every semi-automatic platform is rated for this pressure and cycling profile. Most bolt actions and other manually operated .17 HMR rifles handle this load without any issue. When in doubt, a quick look at your rifle's manual or a call to the manufacturer clears it up fast.
How many boxes come in this case of CCI TNT?
This case totals 2000 rounds, split across individual boxes that run 40 to 50 rounds each depending on how the case is packed. That variation is normal for CCI's case packaging and doesn't affect what's inside each box. You still get the same TNT loading in every box regardless of the count.
How does CCI TNT compare to other .17 HMR hunting loads?
TNT has built a strong following among varmint hunters for its combination of flat shooting and hard-hitting expansion, with plenty of shooters reporting it drops squirrels and prairie dogs more decisively than some of the polymer-tipped alternatives on the market. Accuracy tends to run neck and neck with other premium .17 HMR loads, though as with any rimfire cartridge, results can vary some rifle to rifle. If your gun likes CCI brass, this is a solid choice for serious varmint work.
