I used standard T3 rings on my 300 win mag and 308win for years and never had an issue with them. I also used a 270win for 20 years with no suppressor (ear protection when on the range of course) and had no issues. Personally, I would put that $500 odd towards a better scope (assuming you're not already getting top of the line) and look at changing out the rings and fitting a suppressor later on.
