I saw this post on here where a poster stated that his PWS was "inaccurate". Just curious if any of you PWS owners have experienced accuracy problems with their rifles?

PWS custom machines their own barrels from blanks, and this barrel was no different. They use a 1:8 twist, imparted using a button rifling process (not the most accurate process, but good enough). The chamber for the .223 caliber projectiles is the increasingly popular .223 Wylde chamber, which combines the best features of the 5.56 NATO spec and .223 Remington to accommodate both types of ammunition while maintaining the best accuracy. And on the 100 yard range, it certainly looks like all that work paid off.

This 5-round group was shot using bog-standard 55 grain Federal American Eagle .223 Remington ammunition, also known as “the cheap stuff.” But even though the ammo wasn’t the greatest, the rifle performed remarkably well. The horizontal dispersion of the group was about 1/2 inch center to center, and vertically the group was about 1 inch center to center. I went back and re-tested with some nice Winchester 55 grain ammunition and started getting bored with the 1/2 MoA groups I was getting with the rifle.

There is a small caveat: the gun didn’t like 77 grain ammunition for some reason. I think that the twist rate might not have been ideal for the heavier rounds, and I couldn’t get a good group with even match grade Federal Premium ammunition in that weight.
