What you get with the Howa Mini Action 6.5 Grendel 20 Inch
Howa built the Mini Action around cartridges like the .223, 6.5 Grendel, 6mm ARC and 7.62×39. Shrinking the action to fit those rounds cuts weight and bolt travel, and it feeds from a detachable box magazine.
The 1500 action is made by Howa Machinery in Japan. It’s a two-lug, push-feed action with a one-piece bolt, and the three-position safety lets you run the bolt on safe so you can unload without firing.

Why 6.5 Grendel?
The 6.5 Grendel came out of Alexander Arms in 2003 and was standardized through SAAMI in 2017. It packs 6.5mm bullets into a case short enough for AR-15 length magazines. It’s a capable deer round at moderate ranges and a very efficient target round, with good wind resistance for its size and light recoil.
Typical bullets run from 90 to 130 grains, with 120 to 123 grain loads being the most common. A 1:8 twist handles that whole range. For chamber and pressure specs, see the SAAMI centerfire rifle standard, or read the history of the 6.5 Grendel.
Who should buy it
If you shoot from a truck, a tree stand or a ground blind, the short action and light weight make sense. It’s also a good first centerfire for a younger shooter. A 20-inch barrel keeps the rifle short and balanced without giving up much velocity.
Choosing 6.5 Grendel ammo
Every rifle has loads it likes. Buy two or three different factory loads, shoot groups with each at 100 yards and stick with the one that groups best. Hunting loads cost more, but they’re made to expand and hold together on game. Use them in the field and cheaper ammo for practice.
Hunting rules are set state by state. Start at the U.S. Fish and Wildlife Service hunting page for federal lands, then check your state agency for seasons and caliber limits.
More about the Howa Mini Action
The Mini Action is Howa’s answer to AR-sized cartridges in a bolt gun. The action, bolt and chamber are about 12 percent shorter than a standard short action, so the bolt throw is shorter and the rifle is lighter and quicker to cycle.
Getting it zeroed
Set up at 25 yards first so your first shots land on paper. Then move back to 100 yards and adjust in small steps, firing three-shot groups and letting the barrel cool between them. Once you’re zeroed, shoot from sitting and kneeling too, since that’s how most field shots happen.

Breaking in and cleaning the Howa Mini Action 6.5 Grendel 20 Inch
You don’t need a long break-in routine. Clean the bore after the first few range sessions to get the copper out, then clean it whenever accuracy starts to drop off. Keep a thin coat of oil on exposed steel, especially after a wet day in the field.
