Re: Triangle Groups
A triangle group normally means that the load is not perfectly in tune with the rifle.
Stringing is not good because it can mean so many things,trigger control,bedding, wrong powder
or charge, wrong bullet, wrong seating depth, wrong primer, ETC.
Triangle shaped group can be as simple as parallax, hold consistency or a good load that needs
fine tuning with different seating depths and is a good sign that you are close to finding a
very accurate load combination for your rifle.
I have recently seen this in a rifle that was shooting almost a perfict triangle every time
but it would be orientated differently every time. I could take the targets and overlay them
on top of each other and when I rotated them the group would line up and almost perfectly
match the one below.
Turns out the size of the group(just over an Inch) was the load and the parallax was the cause
of the group rotating.
A scope change and a little more load develoupment cured the probablem.
So the answer to your question is yes,a triangle shaped group is normally a good sign.
