When a brake is installed on a barrel, the brake becomes part of the gun. The holes in a brake or the ports of a ported barrel get a carbon build-up in them from repeated firings. When I clean my guns with brakes I also clean the brakes. When I'm done, the gun is clean and the brake is clean. Its all part of the cleaning process.
I'm late to the thread here but just have to agree on the Vais brake. I've had 4 of them installed now and love them. Not super loud and very effective. And I do shoot prone in the field in all conditions and have never had a problem with dust. Local gunsmith in Rifle Colorado charges $300 though.
The one that came on my Weatherby( Factory ) showers me with debri and pebbles in prone. But, I also made the mistake of shooting at a deer in the dark timber after a heavy snow. It knocked the snow off every Pine tree around me and dowsed me pretty bad with about 8 inches of snow.
After having a few range days with both rifles, the 300 wby with the kdf and the 7mag with the vais; as much as I hate to admit it the vais is a better brake hands down. It has a larger percentage of recoil reduction with less noise. I know they're two different calibers but I've shot both of these rifles with and without the brakes for a long time....vais will be what goes on the 340 wby I have my eye in next and every large bore from here on.
Hunting can be slow and frustrating if Mother Nature throws a warm hunting season at you. But things can take a drastic turn for the better with the onset of a cold snap. Whether you get snow or just a good, prolonged cold front, the hunting can improve on a dime. But cold whether can also make certain parts of the hunt more tedious. Here are some things to keep in mind when your prayers for cold weather finally pay off.
You can see a your quarry's breath when it is cold outside...
