Some more info for the forum please
I am sure there will be forumers along shortly to assist you but you neglect to state the range, ammo, does it have the singer sight finely adjustable or just the flip sight 3-600yds.
The sights are a tad tricky to use and if you have not used peeps before which dependant on where you sit the front blade in relation to the rear peep hole can cause stringing.
Ideally you want the blade in the centre of the rear peep and the top of the blade level with the centre of the rear peep hole, you also do not say if it is off a rest, free hand or with a sling nor what year the rifle is, temperature and so on etc.
The barrel could be a tad tired, have you had a look at the bedding of the action and the barrel there can be a myriad of things that affect the accuracy of these types of rifles and there sure is a lot of people here with far more experience than I to help you.
Also the forum likes lotsa pics so they can asses things they are pretty good at what they do.
Most are long standing armourers from different countries and arms of their respective services or they are highly qualified gunsmiths so you have come to the right place. :thup:
