Let me preface this by saying that my accuracy expectations are based on my experiences with my Chapuis 9.3x74R. That rifle spoiled me; it put 2 pair into 1 1/2” at 100 yards all day long. So, that is my gold standard to judge by. Maybe that is wrong but it’s my baseline to compare against.
Which way to zero a double rifle with what I call only fair accuracy. The factory standard for the company that built this rifle is 10 CM at 100 M so its within factory specs. I have been shooting double rifles for 15 years now and am not an expert but no beginner either. There is always more than one way to look at a problem and I am asking for opinions and insight to possible similar situations and solutions you may have come up with.

I am using Norma 150 Gr. Factory loaded 7x57R ammunition. I have also tried Privi 139 and get similar results. Scope factory mounted and regulated (Leupold 2x7 VX-R scope) in EAW mounts.
Shooting with rifle on my hands, my hands supported with a sandbag in front and up against my shoulder at rear. Fore end is gripped by my hand.

My 7x57R double rifle shoots 2 pair into about 3 1/2-4 inches at 100 yards. Each barrel puts its two shots to its respective side of the bull. Right barrel to right side etc. each barrel puts two shots within an inch of each other.

So, here is my question.
I could zero with a center hold and both barrels will hit 1 ¾”- 2” to either side of center and just accept 4 MOA group average. Or I could zero with the right barrel shooting point of aim/point of impact and left barrel would be 3 ½“-4” to left of that. With this zero I have first shot where I could be precise as hell and second shot most likely game would be moving then. and then there is the issue of threading a bullet between trees in a tight shot.
At 50 yards or less, either zero would be good enough regardless, it is only when getting out to 100 or more where it becomes more critical for good hits. And it is the longer distance that you need the least amount of error.

I am using this primarily for whitetails. At maximum this is a 200 yard rifle. Most of my shots are 50-100 yards but I do have a few meadows I can easily reach out to 200 from a stand. So, what would you do. There are pros and cons to each method.

What are your thoughts.
