Re: Tikka T-3 into a 7 wsm or 7 saum
The WSM bolthead works just fine for the SAUM case. I have done that very thing, 300 WSM into a 7mm SAUM.
However, if I had it to do over again I'd go with the 7 WSM, better brass availability and up to a couple hundred more fps.
Ignorance can be treated with education, sadly there is no cure for stupidity.
