I currently own the MTM Case-Gard Predator Shooting Rest which does a decent job for the most part, but it's clearly a budget shooting rest made entirely of plastic and doesn't offer the kind of stability, adjustability, and precision that I'm looking for. Does anyone have any recommendations for a more 'professional-level' shooting rest that would allow me to secure my rifle in place and then make precise adjustments to the elevation of the front and back of the the gun? Thanks!
