[QUOTE="toliver, post: 1336413, member: 74698"] I tried a little experiment this weekend. I fired ten rounds of exactly the same load. The only difference was 5 had a very light crimp. About the best I could measure was .001 of crimp. The other 5 no crimp at all. No crimp had an es of 21. Crimp had an es of 6. I was a little surprised that the crimped cases were slower across the board as well. I will do a more comprehensive test soon, as the results I believe intriguing. This was a .308 w/175 berger over 43 of varget. [/QUOTE]
