Review: Coretac Solutions Clamp-on Muzzle Brake

A couple of weeks ago I decided it was time to brake my hunting rifle, a Remington Sendero in 7mm Remington Magnum, for the purpose of off season target shooting (it’s not that I can’t handle the recoil, but after twenty or so rounds it does tend to get a tad old). But what route should I take? I looked into some of the options out there. Since I love the look of my rifle without a brake, I narrowed it down to a clamp-on type brake.

I already have a brake from Coretac Solutions on my Savage 110BA in .338 Lapua Magnum and I am very happy with its performance. I purchased that brake due to its smaller size compared to the factory brake and with the additional ports, cuts down on some of the heavier recoil produced by the 300 grain projectiles. This is how I arrived at Coretac Solutions, but I digress…

These brakes are made to order, so, after placing my order it took about three or four business days to machine, coat and ship my new brake. I had it about a week after it shipped.

First Impression

Upon receiving the brake, I must admit, I was pretty excited to install it. Once I got it out of the package, I looked it over for any burrs or debris, it was clean. I pulled out my digital callipers and checked the dimensions of the unit and compared them to the numbers I gave them. Bang on. I retrieved my Sendero from the safe and set it in the tipton gun vice and levelled the rifle. Slid the brake over the muzzle, it was a nice, snug fit. Set it at the stop, levelled the brake and torqued the studs to the specified 85 in-lbs. I then pulled the bolt to look down the tube to check for obstruction, clear. With the bolt still on the bench, I visually checked the alignment of the brake to the muzzle. The muzzle appears to be right where it needs to be.

To the Range!

I did some load development about a month ago with 180 grain Berger Hybrid OTM projectiles along with Retumbo powder. I decided to do another OCW test with the same loads that I did pre-brake. Duplicating every condition as carefully as possible, I then confirmed zero, printing 2.5 minutes low with no change in windage, adjusted my scope and printed 0.1 minutes high. Now to proceed with the OCW, I shot six strings of three rounds in 0.4 grain increments from 67.5 to 69.5 grains, the results were surprising. Originally, found a promising node in the 68.7 grain region. After running the OCW again, the node appeared to be within the same 68.7 grain area, though nearly all of the groups were tighter than the original test. This is promising as it does not appear to alter the harmonics of the barrel (so far); only the point of impact was changed (Keep in mind, this is a heavy contour barrel and changes in harmonics are less likely to occur than with a standard pencil barrel).

Comparison of felt recoil

I did a small comparison between the Sendero with the Coretac Solutions clamp-on brake and my Tikka T3 Varmint in 6.5x55 Swedish Mauser. I found that the braked Sendero pushing 168 grain Berger projectiles at an average velocity of 3075 fps was as comfortable to shoot as my T3 Varmint with 140 grain Sierra’s at 2750 fps.

Conclusion

Five out of five stars. So far, I am very happy with this brake. Currently, I’ve put about fifty rounds down range and can’t wait to send more! It’s a fine piece of kit. Fast and easy to install and remove, no appearance of altered precision, only point of impact (which was expected).Would I recommend this product to a friend? Yes. I will recommend this to anyone that wants to go this route. I believe it’s only draw back is the price which comes in at $275CDN. That being said, as far as I know, it’s one of the only clamp-on brakes that are manufactured in Canada and I chose to support them and keep some of my money north of the Border (not to mention their service is awesome).

Thanks for reading!

(I apologize, I didn't think about writing a review until after my range trip... The pictures above are after the fact...)

PS. I’m in the process of writing up reviews on Timney Triggers for Remington 700 and Savage 110 actions; so, look for those in the coming weeks!
 
looks great, seems you have achieved your goal. and thank you very much for supporting the shooting industry in canada.
i can't help but think that if more people followed your example; we would have even more vendors to choose from, lee
 
My Corebrake just arrived yesterday and it looks even nicer then the gentlemen's pictures above would lead you to believe! Need to acquire a torque wrench that can handle smaller sized bits and I can get this installed, and tested this weekend.

Nice touches: the certificate of authenticity, the lovely little plastic container it comes in (wish I had more of those!) the two-pack of ear plugs and the wet wipes. I'm still puzzling over the wet wipes; perhaps these are for after I crap myself 'cos of how loud it now sounds, heheheh. But all in all, it's a beautiful piece of work.

Yeah... Sorry about that... My camera isn't the greatest. Thanks for the feedback Gents!

I wasn't intending criticism - your pics look better then anything I've ever taken with my phone! I should charge up my camera and start using that again. Phones suck.

Got the torque wrench today as well as a new battery for my decibel metre. If I don't get too rushed this weekend and the weather holds, I plan to do some dB measurements before-and-after the installation of the muzzle brake. I plan on measuring in two positions; the first will be near my head, and the second will be about a metre to my side and a metre behind to simulate the sound intensity a spotter might encounter. Due to the setup of the location where I'll be shooting I (very sadly) will be unable to put the dB meter near the target so I can observe the difference. That would be cool too.
 
Fitted the Corebrake to my 308 tonight to see how it aligns, check for any ah-ha's but it went on like a dream. It wasn't until I got up close with a flashlight and looked at how the chambers were cut that I fully grokked what makes this beast. The alignment was done as per the instructions it came with, and both the brake bore and rifle bore were perfectly concentric looking straight on with a flashlight up the rear (the 700's rear, not mine). It would seem that if you give these guys good measurements, they'll return you an ace product. I'll only have to take a 1" cube of foam out of the case to adjust the fit too.

Everything up until the range tests (haven't done that yet) that the OP says are bang-on. So glad I found CGN! :)

Phones do suck... blsonne, I'd appreciate if you could post your findings with the dB metre. It'd be more great info!

Thanks,

I didn't get around to the measurements this weekend... I intend to this coming weekend, make a day trip to some crown land. Need to buy a cheap pickup or something; this constant vehicle rental is killing me. Nobody told me this activity required a decent sized vehicle along with all the other kit... heh

Finally got around to testing it out, but the dB meter choked and died 'cos of the rain. Dammit.

Honestly, it didn't sound that much louder to me, the shooter, but I don't know what folks on either side would have thought. It reduced recoil a good bit, but not a crazy ton... but it did significantly lower the muzzle rise and I was able to get back on target in what seemed like a lot less time. Then again, I was shooting 150gr without the muzzle brake, and with it on today I was shooting 175gr.

I'll keep trying for a better test with before and after dB measurements. Sorry I boned this time didn't work out :(
