Unfortunately the 15 PC gets very few reviews and little attention. I have one, and honestly, I don't care for it that much. With my best handload that the rifle likes, on a good day, I can pull 1 MOA accuracy at 100 yards. I have groups in my notes ranging from .27" to over 1 inch, it is not consistently impressive. It is a good rifle and well built, but the barrels on these guns are most definitely factory and should not be considered extremely accurate. If you can get another rifle with a better barrel at a similar price point, I would strongly consider it.
The twist rate in mine is 1/8, which is okay, but there is no good reason to have it over a 1/7. 69gr bullets shoot well, but not 77gr in my rifle.
I will say the trigger on the rifle is good, probably half a pound heavier than it should be but extremely clean.
Welcome to the forum. Hope that helps.
