RE: Got the blue sabots
I get 2050 fps with 100 grains and a 180 grain QT bullet. I think you’ll be around 1950 with 90gr. . You can wrap it but I think going from .4 to .358 will be too much. I have used scotch tape and paper to tighten up the fit on my savage. Generally the thicker the sabot, the less accurate, but this is just a general thing and each gun is different.
