Suppressors Using 7.62 suppressor adapter on 6.5, issues?

[Vicarious]

I recently got my replacement Surefire 300 SPS, and since then have got into the 6.5 CM game.

A rather silly question I have is, can I safely use a 7.62 brake adapter on my 6.5 with the can? I am well aware that SF offers a 6.5 brake, but I have a few 7.62 brakes laying around and really don't want to buy another if I don't have to.

I have checked the combo with an alignment rod and it is perfect. Is there any issues with doing this I am not seeing? Destabilization? POI shift?

Nothing will happen.

My breaks are .30and my can is .30 but my rifles are .223 and 6.5.

As long as the threads are correct and the diameter of the suppressor is larger than the diameter of the bullet ... you're fine. I have several rifles that I suppress that way. Oh, and make sure your suppressor is "multi-caliber" ... don't know anything about that brand.

You can use it on anything with less muzzle pressure than it's rated for.

As long as you're running reasonable length barrels I doubt you could ever damage it.

It is a 24" barrel, and it is rated to 300 WM, so no worries there. I was mainly just wondering if the oversized bore of the brake could have any effect on the bullet as it leaves.

I shot it this morning, and oddly, there is a POI shift directly right ranging from 1-1.5". I find this odd because every suppressor I own usually shifts down, or down and somewhat horizontal. Never seen just a straight shift to the right before.

When I tried my 30cal can on a 6.5 Creedmore the shift was about 2" down and 3" right. Groups went from 1/2-3/4 to 3"+. Haven't had the same thing happen when just using a 30 cal brake. That combo seems to work just fine.

Interesting. My groups have pretty much stayed the same size wise, although I wasn't shooting great (too much coffee and I can screw up a good group on a good day).

Shooting Hornady American Gunner 140 bthp, gave a 1.5" shift right with the 300 SPS with a slightly larger group (again, probably me).
Federal 140 fusions the rifle obviously didnt care much for, but only produced about a 1" shift right.
No elevation shift.

I only tried the combo 1 time due to a damaged ego. Now that I'm all healed up I'm going to give it another go. Run a couple of different loads and see if that changes things. Problem easily could have been operator malfunction.

I definitely need to hit the reloading bench. Besides the price and availability of ammo, this is motivating.

Got some Lapua brass, Nosler 140 RDFs and H4350 to try.
