Thanks for that info. Hopefully I shall have some information one way or the other from the importer.

4" group at 100mts I would have to live with but that does show a bit of promis. 5 to 6" at 100 is a slightly different matter.

If I do not have any luck with the importer I will try some homeloads. If no luck with these I will contact Ruger direct.
