jbmi,
Drop me a PM with an email address ... I bet I can help you out with collected load data for the 358Win as I've been doing the same for quite awhile.

Having read JB's article a few times now ... one thing really irked me ... you can't claim the 358Win has a 3% theoretical advantage over the 338Federal, then show data with a 358Win 250gr at 2400fps, then claim the 338Federal is only good for 2200's with a 250gr. Kind of doesn't make any sense.
Cheers...
Con
