Found this on another site, suits me since i am looking for data with IMR 3031 or reloader 15 and 150grain speers. Which is very hard to find thus far. Tell me if this is good advice or bad advice.
"One problem those that reload the 7.62x54R have is that the cartridge is not popular enough to include the amount of data that other cartridges have, such as the .30/06 and .308. Where .308 data in most manuals might include ten to fifteen different powders, the 7.62x54 might only have four or five combinations. The companies do not dislike the 7.62x54, there is just not as much interest in that data. The solution is to use .308 STARTING loads for starting loads in the 7.62x54R. Ed Harris recommended this in an article in American Rifleman some years back. I have tried this with several different powder and bullet combinations, and it works."
Thanks, Ryan.
