My tests on different bedding stuff showed MarineTex and Devcon plastic steel has the least shrinkage when cured hard. Brownell's brown steel filled stuff was a close second. Last place with the most shrinking was Accuraglass.

Tight fit of receiver to bedding is important for best accuracy. Using the thinnest possible release agent helps; I like Simonise car wax rubbed on steel as thin as possible then rubbed hard to thin it.

If what you use is too runny or thin, put a bit of kitchen baking flour in it.
