Here is the last Audette Ladder Test I preformed, I was using a US Model of 1917, Eddystone.
I loaded-up 10 cartridges, I wanted to get the proper vertical POI for 300 yards, (since my sight graduations on this old rifle are fixed.) I of course wanted an accurate load too.
Since I have iron sights I wanted to have the smallest target for a precise POA. I can see a 2moa sized target well at any distance I've tried so far, so I used a 6" white piece of card board on top of a brown piece.
Here is a pic of the ladder test.
The IMR 4064 still had a lot of OOMPH to go, but I stopped at 6 shots since I knew I had the proper POI and my accuracy node was found... I pulled, then loaded-up 3 cartridges with the load specified to test the next day.
Here is a short video of the ladder test, test.
Impossible 30-06 Group
That is the best group I've ever shot with any firearm, scoped or not... Unfortunately, the POI gets higher as opposed to my POA as the distance increases; so that load isn't very useful passed 300 yards.
Here is a short video of a 400 yard vertical POI test.
Not Wasting Anymore Bullets
I do have another 10 shot ladder test loaded to try at 400 yards using Speer 180gr SP bullets. They have a lesser ballistic coefficient and a bit heavier; since I want the load to be a bit slower, and still have some energy.
I'd like to add... all those bullets were pulled twice, and the last 3 were pulled 3 times. All the tips were damaged, and it didn't seem to effect accuracy.
