I have a Remington 700 ADL in 30-06 that I would like to suppress for hunting. The barrel OD is .670 so the biggest thread I can do is 9/16x24. With that thread I can either use a 9/16 to 5/8 thread adapter with any 30 cal can or get a SiCo harvester with 9/16 thread insert.

My question, is 9/16 threads on 30 cal barrel okay?

I have a 30-06 Tikka which was threaded in 9/16 - 24.

It measures .653 OD at the thread shoulder. Whole bunch of rounds through it and no issues to report.

Morgan at Class 3 Machining did the work.

Morgan also threaded my Sig SHR-970 in 9/16x24.

No issues with his work or the threads.

I run a Rem 700 in 308 with 1/2x28 threads and a Griffin Armament Sportsman.   Didnt have enough barrel diameter for 5/8x24 threads, but Griffin Armament said 1/2x28 would be OK as long as I use a lightweight can such as their Sportsman.

Several hundred rounds later and zero issues.    Accuracy actually improved quite a bit when suppressed.

I have done 300 win mags in 9/16 x 24 and 30.06s in 1/2 x 28 with no problems.
