No offense intended, but, instead of "mickey-mousing" that old lens to that fine camera, for $170 you can get a new Nikon DX AF 70-300 (non-VR) zoom that weighs less than a pound and will fit nicely on your D5300. If you want VR, (which most recommend for a lens that goes out to 300mm), the price will more than double to $375 for a Nikon DX 55-300 that weighs just over a pound. (Do NOT get a newer version AF-P lens, as it will not be compatible with the D5300.)
Are you sure the D5300 cannot use AF-P lenses? I have a D5200 that accommodates AF-P lenses just fine.
