Paul, I hope I understand what you are asking. So, this is what works
for me:
1) import the Landsat(8 or any) imagery in a Location defined by their
"native" spatial reference system. In GRASS7, you can do something
quickly from the command line:
# create location
grass7 -c /path/to/georeferenced.image
/path/to/grass-data-base/NameForNewLocation
# import
r.in.gdal ...
# set your region, for example
g.region raster=Imported_Band_1
# create a vector out of the current region
v.in.region out=Working_Region
2) create another location based on the espg in question and reproject
in it the stuff from the "source" Location. Again, quickly from the
command line:
# create location based on given epsg
grass7 -c epsg:27700 /path/to/grass-data-base/NameForEPSG27700Location
# reproject the "region" vector map...
v.proj in=Working_Region dbase=/path/to/grass-data-base
location=NameForNewLocation mapset=PERMANENT #or other Mapset!
# set region usig it
g.region vect=Working_Region
# reproject your rasters -- example below for one image
r.proj input=Imported_Band_1 dbase=/path/to/grass-data-base
location=NameForNewLocation mapset=PERMANENT #or other Mapset!
In general, this is the best way (I know of) to reproject raster data
from one Location to another one (with different reference systems of
course).

I'm having the problem of projecting a source map (landsat 8 image)

target location (Ordnance Survey UK) in Grass 7.
Is it this one: <EPSG:27700> ?
