A PSL54c isn't going to be a tack driver. That being said, there are a few things that you can do to improve how they shoot. I reduced the gas port size to .063" to reduce the recoil and battering on the rear trunnion. I also handload and I have been able to get it down to 1-1 1/2" five shot groups. They seem to like heavier bullets, but the large gas port beats up the rifle with them.
