Self-defense purposes aside, which caliber semi-auto PCC performs the best at punching paper and hitting targets at distance excluding magnum calibers? Mainly comparing the 9mm, .40, .45 ACP, and 10mm. I have a 9mm so far. Debating getting another caliber PCC. The 9mm does pretty well out of a 16" barrel especially with +P loads. Just curious how the other calibers stack up as far as accuracy.
The .45 ACP would be the next obvious choice but the .45 drops quite a bit and I dont know if it gains anything from a 16" barrel like the 9mm does. I can tell with mine the rounds shot from the carbine have quite a bit more power. Everybody says 10mm is the ultimate carbine but 10mm ammo is expensive for a fun plinking gun. I guess .40 S&W would be the most economical "bigger" caliber. But theoretically speaking, most PCCs are blowback and .45 ACP would be the lowest pressure round.
My 9mm is an AR PCC. Id probably build another one if I wanna try another caliber. I havent seen much on 10mm blowback ARs and the one place I did, the guy was having a lot of problems. Many say 10mm is too much of a round for a blowback. So probably just looking at .40 or .45.
Just wondering how these calibers group at distance and compare out of a carbine even though theyre just pistol calibers.
