SRS Brake sizing on my 7mm?

[backcountryplatinum]

I switched from the stock Tikka radial muzzle brake on my 7mm Rem Mag to an SRS 3-port .860 brake.

Recoil is still noticeably punchy — more than I was expecting. After doing some research, I realized I received the .30 cal version of the SRS brake instead of the dedicated 7mm version they offer.

From what I can tell, the bullet clearance is roughly .026" greater with the .30 cal brake. Is that a meaningful difference in recoil reduction or not really?

I’m planning to move up to the 4-port version, but in Canada the only one currently available is again the .30 cal model. Should I wait for the 7mm version to come back in stock, or is the performance difference negligible?

Thanks.

Try the 4 port. I have it on my 28 nosler and is great. I wouldn’t think the diameter being that much more would be significant but there are others who will chime in that know more than me

30 cal is fine on a 7mm, more ports will make a much larger difference than a caliber specific bore.

But a 7mm would be more ideal?

It'll be .0007% better.
