Thank you all for confirming my suspicions
. It's no wonder the stalkers (deer hunters) in the UK buy other makes as not only are our native deer smaller in the most part than the American Whitetail and Mule Deer butt he meat is more often than not sold to the game dealer for processing and sale onto to the meat and resturant trade. I stalk fro my own benefit and do not sell to the game dealer.
The favoured shot of these meat harvesters is the neck shot and a rifle that does not shoot at least MOA is no use to them at all. A Roe deer's neck in total width is only about 3" wide, Muntjac deer are smaller. Even in Fallow deer the target area for the neck shot is only about an inch. For those who might not realise the Roe Deer which is an ancient species and native to these islands has a heart that is under 3" in diameter the Muntjac which is an almost prehistoric species brought in from Asia during the late 1800's and since colonised has a heart more like 2". The Muntjac stand about 2 feet tall and weighs about 30lbs for a good Buck but man are they fine eating
here is a full grown Doe taken by myself some years back:-
perhaps you cans see why better precision in grouping is desirable. far to easy to destroy the loins or saddle and lose some of the best cuts.
One can see the entrance wound on this Doe in the front of the chest. She was not in an ideal spot and at about 160-180 yards shot taken from a high seat (elevated box blind) so there was a solid rest.
Roe Doe for comparison with same Rifle. Using an 8" kill zone of Roe could result in too many gut shots. Some say 6" others 5" for Roe.
Personally I do not like the upper neck shot same as I don't like head shots. The lower neck is better IMHO but I'll much rather take high heart/low lung any time I can get it
.
Now back to the OP's query/question. No I would not be happy with any new rifle when fitted with a good scope and mount set up that could not produce better than 2" groups. The OP does not mention how many shots make up that group so we will have to work on the favoured modern Three round group. frankly I expect that from an iron sighted rifle not a scoped one. My maximum group size that I would be happy with is 1 1/2" for Five shots at 100 yards. if the rifle does not achieve this I work with it until I can but until then it does not go hunting. So far I have managed to achieve this with every rifle brought for hunting use.
Some old Milsurps have not managed this but then again they were not intended for hunting and were often shooting ammunition far older than I am.
Sadly the OP has little option if he wants to keep the rifle than try some thing like fire lapping and hope it shows some improvement failing that live with it and forever wonder if it could do better or re-barrel. A friedn in Missouri had very good results from fire lapping a poorly performing barrel.
