The horn without a mute plays dead on in tune. With the mute my Eb is nearly in tune E

How sharp are most practice mutes?
I've heard pairing a mute to a particular tuba is trial and error. Any suggestions for another mute be welcome, or any tips to resolve the sharpness with this one.
Most of the threads I found searching were just bashing mutes, didn't find anything on decreasing the sharpness caused by them other than pulling a slide.
