A post on CGN about an 8.5x55 Blaser got me to searching info to see what it was about, ran across a new to me site, that may have info a person can use on bullets, powders and data. It is set up like Load Data from Petersen, some free, some protected stuff you pay for, but, may be well worth 10.00 to find out what they have there. Worth exploring, has some different stuff in it.
