Home Forums Hunting & Shooting Air Guns Same gun - which is quieter, 22 or 177?

I'm considering purchasing a Benjamin Fortitude PCP rifle. I can't decide on whether to get it in 177 or 22. Which of the two would be the quietest?

I would think the 22 would be a little quieter, IF they both fire with the same volume of air. The 22 would have more bore volume, and less muzzle pressure.

But who knows if the difference is even enough to make a difference?

The good news is that DonnyFL supports the Fortitude with front end adaptor, and that opens the door to any of their moderators.

Fortitude does not need a DonnyFL moderator. I have a .22 caliber Fortitude. It is incredibly quiet as it comes from the factory.

I bought the Fortitude for a pest control job that I was contracted for at a local park. I was looking for something a little less powerful than my .25 airgun and quiet. It checks both of those boxes. Very accurate. Very back yard friendly. I'm getting about 70 shots at 650 fps with JSB 18.13 gr Jumbo Heavies. I'd like a little more power for another, ongoing bird control job as range can get stretched out there and some of the target species are of a larger variety but the accuracy and high shot count between fills has me taking the Fortitude more often than not. Once you get to crow size birds and larger the .25 really shines. If Benjamin ever chose to offer a Fortitude in .25 or .30, I would put one in my shopping cart instantly. For the cost of a Fortitude, you get a lot of bang for your dollar.

Easy trigger mod to lighten the trigger pull. Basically replace the stiff return spring with one out of a ball point pen and a slight bend on the other spring is all it takes. Videos on this are floating around on Youtube. My only complaint about the fortitude is the pistol grip. It seems just a little thick to me and I don't have small hands.

How well does your Fortitude hold air? What I need is a rifle that I can sit in the corner for maybe up to a week or two at the time before I shoot it a couple of times at a squirrel raiding the bird feeder, etc. Will it be ready, or leaked down and useless?

And BTW, thanks also to everyone who has responded so far.

The Fortitude does not leak air. None of my PCP airguns have had an issue with losing air. Including a Korean made Career that I've owned for over twenty years. Set them in a corner for weeks or years, doesn't seem to matter.

BTW- that Career without a moderator is LOUD. With a moderator it's backyard friendly but still louder than the Fortitude. The stock Fortitude is quieter than any of my other airguns with moderators added.

It looks like they fixed the trigger on the latest models...from the Pyramyd Air description-
"The Fortitude Gen2 Upgrades Include:
Reduced Cocking Effort
Reduced Trigger Pull Weight
Adjustable Hammer Spring Tension"

All of that is good news. As soon as a Fortitude becomes available in .22, I'm going to purchase it. The .22's are backordered everywhere right now.
