I had a beautiful BSA lightweight sporter in .30-'06, the one with the built in muzzle break. It worked, but man, was that little sucker loud! BSA chambered those rifles in calibres up to .458 Winchester in rifles that weighed just 8-1/2 lbs. The mind boggles .....
Scoped, it was so light, I could hold it with one hand like a pistol. Wouldn't have fired it that way, though. From the bench, it would consistently group 1-1/4" to 1-1/2" with anything I fed it.
At one range where I shot, there were coffee cans hanging on nails on the posts between benches. When I fired, the cans on either side of me would swing! People would look at me with "WTF?" on their faces. Shooting that rifle even a few times hunting took a toll on my hearing. That was before 'lectronic muffs.
A 'smith told me the solution - after I sold the rifle. Thread and sleeve the 1-1/2" on the rearward slotted brake. When I wanted the brake, I could simply unscrew the sleeve or lock tite it in permanently. I miss that rifle .....
