How does the 338 ARC compare to 300 Blackout for subsonic use?

Subsonic 338 ARC ammunition reportedly delivers approximately 250 more foot-pounds of energy than subsonic 300 Blackout. This makes the 338 ARC a more potent option for short-range hunting applications where increased stopping power is desired.

What are the magazine compatibility notes for the PSA 338 ARC pistol?

While PSA officially guarantees function with Duramag 400 Legend magazines, the review found that Grendel magazines from Duramag and C Products, as well as a 25-round Grendel magazine, also functioned reliably without feeding issues in the 338 ARC pistol.

What are the main drawbacks of the 338 ARC caliber?

The primary drawbacks of the 338 ARC caliber at this time are the scarcity and high cost of ammunition. This makes it a less accessible option for widespread adoption compared to more established calibers like 300 Blackout.

Is the PSA 338 ARC pistol suitable for hunting?

Yes, the PSA 338 ARC pistol is considered suitable for short-range hunting, particularly for hogs and deer. Its increased subsonic energy output compared to 300 Blackout provides more stopping power, and it achieved adequate groupings for ethical shots within 100 yards.
