Thread: Drilling holes out in suppressor

Hi all.
Im wondering if its acceptable to drill holes out in a suppressor...?
I have a dpt magnum 7mm/270 cal suppressor i would like to open up for a 308.. is this a thing or am i dreaming? I have the tools and skills but dont want to wreck a near new suppressor if it doesn't work out.
Would ideally like to run the same suppressor on both rifles if i can.
Any input would be appreciated.
Cheers
