Hello,

I have made a few other posts about group size with specific size bullets (mainly 180's out of my R1).

Either way I got some Barnes 165's today and sent some lead down range @ 1 and 200 yards.

The results were interesting in that I shot 2 4 shot groups at each distance letting the barrel cool in between each.

All 4 groups were about 4" both at 100 and 200?

I always assumed if I the shooter was making some mistake (flinching, not handling recoil, sloppy form) the group would open up at the 200 yard range.

I can shoot almost MOA with my 30-06 and 270wsm, but never really get better then 4" groups with the .300win.

At this point based on the results is it the gun / scope that cant group better then 4" or is identical groups of that size at 1-200 common ?

Thanks!
 
So here is something to try:

Set up your rifle and put up your target at 200 so you are on paper with your reticle. Then also set up a target at 100 so that your are also on paper without having moved your rifle. Shoot at your target at 100 and you will also hit your target at 200 and you can see what change in group size occured.
 
Those old 3-9 Conquest have a terrible fixed parallax setting. When I mount those 3-9 conquests for people and set it in my boresighter, if I move my head just a tinny bit, the recital will move a full square on the grid in any direction.... That's 2" of movement at 100 meters in any direction were the point of impact is sighted too because one square on my grid is 8 clicks at 100 meters. That means your groups could easily grow to 4" with that scope at 100 meters by simply not placing your face on the stock in exactly the same spot you had it last time. Try shooting it again but don't move your head off the rifle as you shoot and reload. If its easier for you, then place some tape on your stock where your noise should be to know you're in exactly the same spot as before.

Please, for the love of god, don't put your face anywhere near where the noise should be!!
 
I have found a similar thing happening with my drilling. I worked up a load it seemed to like. It’s a 175 grain ELDx out of the 7x65R @2550 FPS. I intended on setting it at 2” high at 100 hoping for a 200 yard zero at 200. I zeroed at 200 and now am zero at 100 as well. The pattern opens about 1.5 MOA, but the zeros are the same. I’m down 8” at 300.

Overall, I am surprised and happy but don’t know why the zeros at 100 and 200 are the same. My Dad suspects it has to do with how far the scope is above the rifle barrel (quite high on a drilling). Anyone here able to explain it?

So I should try a new scope and see how my groups look? Anyone like the new vortex diamondback tactical?

Seems a good scope for the money.

Your 100 and 200 yard zeros are the same because the bullet is rising at 100, peaking somewhere around 150 and falling to the same elevation at 200...

Thanks cosmic. I missed the OP’s issue is different than mine. Mine is not a bad thing in my books. I’m happy with them having that flat of a trajectory.

The Diamondback Tactical 30mm or the Daimondback Tactical 1"? If its the 1", no thanks. They have a terrible field of view. The Daimondback Tactical 30mm is okay just keep inmind that its a FFP scope for $500.... That means its cheap... like really cheap. The field of view fine enough. The image is serviceable, it has adjustable parallax, but its turrets are sloppy. If you made a quick adjustment for a bullet drop of ,just an example, 5.4 MRAD, you will have a hard time trying to tell if you're on 5.3, 5.4, or 5.5. Its that sloppy. For the same price, the Bushnell Engage 30mm Tactical is a much better scope only its SFP and MOA. My only complaint about the Engage Tactical is they didn't number their MOA in the retical but instead added a thick line for every 5 MOA. Sometimes when I'm ranging my target at distance out to 400 and beyond I can easily miscount just from a slight shake. Also, you quickly understand why an illuminated retical is necessary because its impossible to range your target if its black. You can aim off to the side of it and count but its just not ideal especially if your target is on the edge of a clear cut and the forest behind it is dark too making it so you can't see your lines.
