Bone stock Notos and as my first mod I did the FX 500mm barrel kit. I chose the superior heavy liner as I plan to mainly shoot slugs. I haven't touched anything else but the barrel swap.
So I was shooting 15.4 gamo pellets @740ish and 23gr NSA slugs @ 650ish. After the 500mm kit I lost quite a bit of speed. The 15.4s are 660ish now and the 23gr are 550ish.
Any one have an idea as to why? More curious as to understanding why the loss in speed.
I plan to fully port and big bottle/reg swap too along with custom spring and hammer stuff too at a later point. So I know I'll pick up speed at a later point.
