Big Redhead,
I had to get out my #13 Speer manual after your comment about the differences in 7x57 data between 760 and 414. Here is what I found...Pleae note that in only one bullet weight is there a 1-grain difference in the maximum powder charge. The others are all exactly the same.
Good reply, JB. Sorry, I was wrong. So much for posting "facts" from memory. Thanks for setting the record straight.
