> There's been some criticism over that thinking they should have made the bullets for it in more of a 358 you know standard rifle uh 35 caliber rifle rounds.

> It hits just a little bit more than a five five six you get a little bit more jolt but not a big deal at all.

## What Customers Say

*AI-generated insights from customer reviews*

Owners of the CMMG RESOLUTE 300 in .45 ACP generally come away satisfied, particularly on build quality and reliability. The adjustable stock draws consistent praise for making the rifle comfortable across different shooters. Accuracy at range distances gets positive marks as well.

The .45 ACP chambering is both a selling point and a common discussion topic. The stopping power is appreciated, but ammo availability and cost in .45 ACP is a recurring concern compared to 5.56 or 9mm. Weight at 6.8 lbs. is occasionally called out as heavier than expected, especially during longer sessions. Price sits on the higher end, though most who own one consider it appropriate for the quality level.
