Finely had some time to test the .25-06 AI Cooper Excaliber with 26" Barrel. Your opinions are wanted in helping determine a good OCW load.

Ladder Test.
Components:
- 115 Grain Bergers (.05 off lands),
- Lapua 30-06 Fire formed brass,
- CCI BR2 Primers,
- Reloader 22, and
- IMR 7828sc.

Conditions:
- 15-18 Deg C,
- Mild right to left wind,
- 300 yards,
- busy range.

1st Target at 300yrds with IMR 7828sc:

I was thinking for Target 1 / 7828sc would be best to look around the 59.1 - 59.4 range.

2nd Target at 300yrds with R22:

For Target 2 / R22 would be around 58.5 - 58.8 range.

300yrd was a little close as the targets are pretty clustered, I went .050 off lands as the prior tests with R22 showed it to be the most accurate with .010 off coming in second.

Quickload shows I can go about another grain or so up in powder charge for both powders but I was just starting to see pressure signs at 60grs, and with more then enough velocity call it my Max.

What do you guys think?
