Home Forums Hunting & Shooting Hunting Rifles Deer rifle with a suppressor

1/2x28 threads work fine with larger calibers, as long as there's enough meat between the bore and threads.....most smiths want to move up in size for anything larger than 7mm to 30 caliber.

This stuff isn't complicated.....take your rifle in to a reputable smith, have him cut your current barrel to whatever length you choose, thread it 1/2x28 (as long as you have ~.6" of barrel diameter at your chosen muzzle length), and use a thread adapter to fit your suppressor. Bring the thread adapter with you so the smith can fit the threads, that will ensure close mating and limit the chance of a baffle strike.

I recommend going 16-18" on barrel length, because with a 7" suppressor the overall rifle length will be close to original factory length. That means the rifle will retain a handy overall length, and the balance won't be so badly affected....especially compared to starting with a 20" heavy barrel to begin with...those babies are incredibly front heavy when a suppressor is added, unless you use a 30 ounce scope and magnum fill stock to balance it out, then suddenly your rifle weighs 10+ lbs and isn't any fun to carry around.

A 16-18" 270 will still have plenty of speed to expand decently slick bullets to ranges further than any of us has any business shooting at unwounded big game, and the rifle will remain handy enough to hunt the brush. Win/Win.

Do you have a dial caliper to measure the diameter of the Tikka where you'd want it cut? 20"? 18"? or leave at 22"? Measure it and let us know what it is.

Most of the 223 suppressors aren't rated for 22-250, so I'd go 5/8x24 threads and use a light 308 suppressor.

There is a thread in the classifieds here - a smith in Dallas, I think, doing threading work and discounting if you have more than one. Check that out and contact him to see what he recommends.

Here's .655" diameter Brux #3 threaded 5/8x24 by LRI.

I have not found Tikkas to have enough meat for a shoulder when threading to 5/8-24 for most common 30 cal suppressors.

I have done about 5-6 T3s now and have pressed a shoulder behind the threads on all. I have done one .223 threaded at 1/2-28 and it had plenty of meat for a sufficient shoulder.

I would guess the "shoulder ring" is an interference fit?
If so, does it have a constriction in the bore beneath it?

I have not done a gage ball drop test but I highly doubt there is a constriction. The rifle still shoots 3 shot touching groups regularly. There was a very small shoulder after turning the area to be threaded to .625". If I recall about .020-.030 per side, so the ring has at least something to stop against. You don't need a major press fit. The ring is slip-light press fit with LocTite cylindrical bonding compound applied.

So the ideal process is to turn the muzzle OD to .625 for the proper length (desired thread length + length of shoulder ring), install shoulder, thread from muzzle to shoulder.
