.020 over bore size is the usual . You'll be fine if everything is straight .
I've experimented with clearance from , well let's say very very close to ..080 over . No noticeable difference .
Difference in accuracy ? I have a Brux barrel .

Its not going to be effective. Most good ones are bored after installation and are not universal
I’m going to send it back, exchange it for 6.5 and have smith open it up
Hope Patriot Valley Arms will exchange this brake for their 6.5 version . Don't want to be stuck with a Boat Anchor .
