refurbished rifle accuracy problem

[dougie]

I just had a mark 10 Mauser 30-06 prettied up with an MPI stock(fully floated and bedded of course by myself),the barrel shortened to 22" from 24", recrowned and teflon coated. My problem is that it doesn't seem to shoot nearly as well with the same loads as before. What should I do?

By shortening the barrel by 2" I think you may have changed the barrel harmonics. You will probably have to at least tweak your load if not rework it altogether.

Dito. You have a "new" barrel, better start over with new loads or tweaked loads IMO.
