G'Day all,
well................I got it up to 25.6gns of 2208, but it wouldn't shoot, now I'm using 25.0 and the ES is extremely low. Three readings identical of about 2885pfs from memory. I may test further but it shoots real nice so who really cares. I reckon its due to doing a full BR case prep for consistent ignition. I jump the bullets about 0.005" from the bullet jam figure (thats where the bullet is pushed back into the case cause it is too long) I need to get at least 3-5 readings the same before I am confident of achieving that jam figure.
Of course approach this load approx 10% or 2.5gns less than posted for safety's sake!

I find Rem 7 1/2 more than adequate for 25.4 gn 2208 in winchester brass and just happend to be the sweetest load I have found to date for MY rifle. Remember to test just one component at a time and record results...your brain is not a notepad.
You may want to conduct a ladder test with various components to find a load to suit YOUR rifle.
This can be quite time consuming (call me slow but it took me 12 months to get it right) but at the end of the day, is the only surefire way to to get accurate ammo.
