Forgive me for hijacking your thread Clark,,,,

Dr. Mike, where did you find that 145 grain ELD-X bullet data? I could not find it in my new version QL.

 

[DrMike]

The data was included in my data set picked up in January (QL Update dated 17 DEZ 2017). It is listed as an ELX-X. However, the name appears to be a typo, since it looks to be an ELD-X.

Man, I would have expected more from 26 and the 145 ELD in the 270WSM. Wonder if it is the 22" barrel or what, but I would have thought for sure that would have been a 3200 sorta load pretty easily. That is pretty interesting.

Not that 3100 is a slouch, but my 22" 270 Win does 3030 pretty easily with 150 ABLR's and 26..
