Bore size?

Yes, it can be legal to make a silencer. For everything Form-1, from silencer designs that are easily made, to filing forms with the BATF, to 3D modeling. Remember, you must have an approved BATF Form-1 to make a silencer. All NFA laws apply.

There is no "standard" suppressor aperture diameter for a given caliber.

I would make the aperture diameter 20% greater than the barrel groove diameter as a median reference. Then, adjust that value for tolerances, length, concentricity, etc.

You could also use a tapered hole design.

That would be about .360
I was thinking .375 but was nervous about clearance.
The primary host will be a romanian sar-1 and also will go on my savage 111
would .400 be overkill?
Thanks

.400 is not the best bore size but it certainly isn't "overkill". Typically a larger bore/tapered bore lead to less blowback as it is harder for the gas to come back into the barrel than it is to leave the silencer.

The std is .375 and that's based on checking cans from Gemtech, SWR, SCRC and AWC in the past.

If you're not part of the solution, you're not only "part" of the problem but, you "are" the problem.

We have a .334 bullet channel in our .30 calibre NorthStar suppressors and a .342 bore on our jet-Z suppressors.

It would look to be tighter compared to many of the U.S. suppressors, however we have not received many complaints about accuracy or excessive point of impact shift, with thousands of the above mentioned suppressors sold over the last 10 years.

All our suppressors are checked atleast twice during production and our warranty return numbers are very few yearly anyway.

Regards!

this is exactly what I would have guessed. holding a 30 caliber bullet to a 3/8ths hole looks like it fits the bill to me.
