i have an 18.5" ported barrel on my 45-70..I don't think it is all that bad.Everyone is different to there tolerances but for example,if you have ever shot some of the Big Bore handguns,it won't be much different.

Those get right damned loud.
I've also got a Guide Gun, though unported, and the report is somewhat more pronounced than a 22" version.
If I'm inclined to use a shorter barreled rifle, I am willing to accept the slightly elevated noise level. Comes with the territory.
