Description

CCI .17 HM2 17 Grain V-MAX — 500 Rounds

The CCI 17 HM2 is the rimfire varmint load in the 17 HM2 category.

A 17-grain Hornady V-MAX at 2,010 fps and 152 ft-lbs, produced on the .17 Hornady Mach 2 platform with CCI’s Sure-Fire rimfire priming.

At $0.49 per round for 500 rounds, the CCI 17 HM2 is the volume buy for shooters with chambered rifles seeking bulk supply in a caliber that has become increasingly difficult to source.

.17 HM2 vs .17 HMR — Not the Same Cartridge

The .17 HM2 and .17 HMR are distinct cartridges and not interchangeable. They require different chambers, different barrel dimensions, and different headspacing.

The .17 HMR is based on the .22 WMR case necked to .17 caliber — a larger, more powerful rimfire.

The .17 HM2 is based on the smaller .22 Long Rifle Stinger case — lighter construction, 2,010 fps vs .17 HMR’s 2,550+ fps, and 152 ft-lbs vs .17 HMR’s ~250+ ft-lbs.

Do not attempt to chamber .17 HMR ammunition in a .17 HM2 rifle, or vice versa.

The V-MAX Bullet at Rimfire Velocities

The CCI 17 HM2 uses Hornady’s V-MAX — a 17-grain polymer-tipped bullet designed for rapid expansion on small varmint targets.

At 2,010 fps, the V-MAX produces reliable expansion on ground squirrels, mice, and similar small varmints at ranges appropriate to this cartridge.

The polymer tip ensures consistent expansion initiation at all practical ranges.

Combined with CCI’s Sure-Fire priming for consistent rimfire ignition, the CCI 17 HM2 is a reliably accurate varmint round from a major manufacturer.

CCI Sure-Fire Rimfire Priming

CCI’s Sure-Fire priming compound is applied uniformly around the case rim to eliminate dead primer spots.

Inconsistent priming is the primary cause of rimfire duds. Sure-Fire reduces this failure mode for reliable ignition in cold weather and semi-automatic actions.

Frequently Asked Questions

What is the .17 HM2 and how does it differ from the .17 HMR? Two completely different cartridges that happen to share the same .17-caliber bullet diameter. The .17 HMR (Hornady Magnum Rimfire) is based on the .22 WMR case — it’s a larger, faster rimfire at 2,550+ fps. The .17 HM2 (Hornady Mach 2) is based on the smaller .22 Long Rifle Stinger case — 2,010 fps, lower energy, different headspace dimensions. They do not interchange. A .17 HMR round will not chamber safely in a .17 HM2 rifle, and vice versa.

Is the .17 HM2 still in production? The .17 HM2 has been discontinued by several manufacturers and is no longer as widely available as the .17 HMR. CCI remains one of the primary suppliers of .17 HM2 ammunition. If you own a .17 HM2 chambered rifle, bulk purchases are advisable when stock is available.

What does the V-MAX bullet do on varmints? The Hornady V-MAX is a polymer-tipped, thin-jacketed varmint bullet designed for violent, rapid fragmentation on impact with small targets. It expands and transfers energy very quickly — producing reliable kills on ground squirrels, prairie dogs, and similar small varmints with minimal ricochet risk. This is the opposite design philosophy from bonded big-game bullets, which are built to retain weight and penetrate.

What is “Sure-Fire” rimfire priming? CCI’s proprietary rimfire priming compound, applied uniformly around the full perimeter of the case rim. Rimfire duds occur when the firing pin strikes an area with insufficient priming compound — Sure-Fire’s uniform coverage eliminates this failure mode, providing consistent ignition in cold temperatures and semi-automatic cycling.

What’s the effective range for varmint hunting? At 2,010 fps, the .17 HM2 has a usable varmint range of approximately 100–150 yards — shorter than the .17 HMR’s 175–200 yard effective range. It’s best suited for close-to-medium-range hunting in fields, barns, and small agricultural settings.

Is the casing reloadable? No — rimfire ammunition uses a primer compound in the case rim, which is consumed on firing. Rimfire cases cannot be safely reprimed and are not reloadable.

How many rounds is 500? 10 × 50-round boxes.

What’s the per-round cost? $245.99 / 500 = $0.492 per round.
