Screw on vs. Ported muzzle brake

[daka]

Recently I sent my two guns for muzzle brake install and some other work as well. Guns returned and I am really satisfied with all of the work that was done but almost disappointed with muzzle brake installation. Instead of removable/screw on muzzle brake, gunsmith ported the barrels.
I read some scary stories of decreased muzzle velocity affect in accuracy, real sensitive reloading practices, not being able to shoot accurate in rain and so on...
original barrel length is 24.5 inch and I guess now ported length decreased that to 23 or 22.5 like non magnum caliber.
Can I hear some pros and cons about the both options.
Gun is 270WSM Sako that was intended to be used for sheep and goat hunting, (mountain in general).
thanks ahead

Shoot it, see how it does. If it has issues, you can always have it cut, recrowned and threaded. I personally wouldn't want something like that, but on the same note I personally have only shot handguns that were ported like that, so no personal experience. If your concerned about rain while hunting, just tape the muzzle. That is what I do pretth much anytime I go in the back country on a hunt.

What suprises me the most is that the smith did not tell you he was going to port it that way instead of the conventional method. I personally would have been upset at the lack of communication, but then again when I have a brake installed I specifically tell the smith what thread diameter/pitch I want, and supply my own brake.

Gunsmith did it same model of the gun for friend of mine and he installed removable one. I asked him to do the flush screw one brake. Don't know why he did what he did, everything else was done great.

I would be interested to know how he deburrs the rifling areas after cutting into the barrel like that.

Is it still rifled out to the end of the muzzle? Or did he back bore it and port the bored section?

Looks like back bored and ported. It does look like a crown at the bottom of the bore.

Are you sure he didn't just get a perfect blend on the barrel to the muzzle brake?

He told you he ported the barrel?

measure your barrel length now

That was what I was thinking. Its a screw on blended/polished in.

That sounds more like a really well blended brake, vs magnaported. Ya, pictures would be helpful

Barrel length was and still is 24.5 inch as factory length was.
I don't doubt his work, it looks as really good quality work but would rather want to hear pros and cons between integrated/ported vs. Screw on muzzle brake. Was setting it up to be my LR hunting gig.

Other gun is Tikka 223 and it is also integral ported brake but that one is more of a coyote gun for kids and not that worried about.

A screw on brake can have a much bigger and more aggressive first port because it can be drilled out to almost the muzzle thread diameter rather than the bore diameter.

I think you probably got a blended brake and maybe there was a miscommunication that resulted in shortening the barrel to keep the length the same with the brake.

 

[daka]

Can someone let me know what pros and cons are to ported vs screwed brake. Interested in affects of LR and reloading for ported brake.

Beside the fact that a screw on brake can have a bigger more effective first port, it can also be heat treated harder than a barrel, it can be an entirely different material, it can be re-timed if the barrel gets set back or otherwise changes.

You can also take off a screw on brake to shoot it with a plain muzzle or change it with a brake that is improved in recoil reduction, blast reduction, flash reduction, kicking up less dirt or put on a suppressor.

I think that is all pretty obvious except the bigger first port part.
