Perhaps. But it’s a pretty simple solution to try some different seating depths to see if it works itself out. I’m sure someone much smarter than me might have more input as to how to relate the two. But it’s worth a try. If no improvement, look elsewhereIs there a technique for relating seating depth to horizontal spread? I remember in archery you could read the paper tears so you could adjust the rest, spine, etc...
Many years ago when I was just getting into rifles and deer hunting I read some where that the .50 big had nearly identical ballistics as the 30-06. The .50 shoots 500 grain bullets and 06, 150 grain. I don't remember the exact load data for either, it was 30 years ago! Technology has come a long way since, and this may have been disproven by now however if this proves true then you should be able to duplicate the flight path of the creedmore with the 308 or certainly 06 or Win Mag. Bc and sd being the same or similar and velocities to accommodate for change in bullet weight. However recoil would also increase and maybe that is why the creedmore is becoming so popular. That's why I went from 06 to 308 and also have a 243. From what I've read the creedmore is mild on recoil as is the 257 Roberts. I just don't see the need for a "new" caliber unless there is a significant improvement over what's already available. My understanding is that the main advantage to the creedmore is that ammunition manufacturers are putting much more quality control into creedmore ammo. If the would have done that with 25-06, 264 Rem, 6.5x55 and 257 Roberts the creedmore advantage would probably disappear.If they were exactly identical velocity, bc / geometry, bullet weight, and fired from barrels that exhibited exactly identical harmonics, then you could reasonably expect the same flight paths from 2 different calibers. Someone correct me if I am mistaken.
I must be missing something. This is a hunting rifle, and that group looks to be .6 moa or so at 400 yds! What's wrong with that! It'll kill anything you shoot it at?!?
Now, if you want to shoot bugholes and benchrest, get a diff caliber, a 25 lb plus rifle, 40-50 power scope and an adjustable front rest, rear rabbit ear rest and a bunch of wind flags
When I first joined this group I was in load development and got hammered for my 100 yard 1 hole groups.You're 100% on 100 yards, not being reliable?!
