^^^ What he said ^^^

When you stretch a .270 dia. cylinder to .358, you will reduce the wall thickness by a factor of 0.75. So, necks that are .014" thick will become 0.011".

Stretching an '06 case will result in a factor of 0.86, yielding 0.012" necks.




Thanks for the insight as to why .30-06 was recommended. I have currently resized a little over 100 .30-06 cases into .35 Whelen, and loaded them multiple times without issue. I also have a stockpile of .35 Whelen factory brass.

This was more about finding a use for the .270 cases. If they aren’t safe bring necked up so much, I may just find them another home.
