Quick question here on making dummy rounds for a 7 SAUM I'm having chambered. I was watching a Greg Tannel video on setting up dummy rounds and he says that to allow .050", but .100" under mag length is better, but seeing how tight this cambering is as far as mag space, would it be better to go with .050" under mag length?

I would venture on the side of caution with the SAUM. If you throat it too long, it won’t be long before you’ll be out of mag space trying to chase the lands. A caliber that doesn’t quite eat up a barrel as fast I might consider .050”
Thanks Geno. I'll go ahead and seat them at the deeper .100" I should be ok with the powder I'm going to use.
