I picked Alliant Reloader 15 and Accurate XMR-4350 because those are two powders I have in stock that are in the right burning rate range for the 7mm-08. I'm pleased that I got accurate loads with the XMR-4350 because I have an 8 lb keg of it.
The best group was with cheap Winchester 150 gr bullets over 46.0 gr XMR-4350.
The other two groups above were with the Nosler Ballistic Tip 140 gr bullet.
One was with 48.0 gr XMR-4350 and the other with 42.5 gr Re-15.
You need to work up to these loads in your own rifle. I took the max loads from the Alliant and Accurate web sites then reduced them by 8% and worked back up to max in 2% increments.
All loads were in Winchester brass and CCI-200 primers were used. All the XMR-4350 loads are compressed.
I still have some testing to do with the Hornady 154 gr Accubond.
