I would think that the M44 would need a brake WAY more than the 91/30 long rifles. Those things tend to thump you when shooting 180-204gr bullets.
I'm sure it would also increase the noise levels, but I imagine most people that see the need for a brake are not as concerned about noise as they are pain management..
I'll have to wait til I get home to measure my M44.. hopefully someone else will be able to do it before this afternoon.
