I have found the USRAC Model 70's sometimes had bedding problems and required that a small Accraglass land about 1/4 inch wide and 0.050 inches high be cast between two 0.050 thick plastic shims. This should be done in the stock's fore-end tip barrel channel not more than 3/8th inch back from the tip.
Make sure that the shims and barrel are coated with release agent and remove the shims after hardening and trim the edges of the Accraglass land with a razor. This bedding method will often cure stock bedding issues and will tighten up groups.
I have done the treatment on three Featherweight and two Sporter, USRAC Model 70's and it improved grouping and group consistency on all of these rifles.
