I sorta played with my T with the bag up the front like yours pictured and the groups were not what I considered very good so I ditched the bag and went prone with it and shot a clover leaf 3 shotter at 100m you may want to invest in a repro WWII adjustable sling as a standard one is rubbish on a T (Of the type as pictured on my S51 '44). This one was made by one of the club members but has since been swapped out with one I purchased from the USAyou could buy a WWII one but all the ones I have seen are badly crazed and would probably tear apart unless they have been exceedingly well looked after. Hand-loads may get you better groupings as well Mk VII ammo now is getting collectible and may be a bit erratic in ignition. Nice looking rifle.
