AF Texan SS vs LSS

Figure that projectile weight on the Texans have a lot to do with how much air it moves per shot. A Texan shooting a 145 grain roundball at 900fps will be a lot quieter than the same gun shooting a 290 grain slug at 900fps. 

That’s one way db tests may be misleading. 

The biggest difference between the two is the fps the longer barrel on the lss really makes the difference for heavy slugs. 

That being said the LS shorter barrel is much easier to handle and walk around with. Both are very quiet when compared to the carbine or standard Texan. Even so neither so much so they will not startle game when fired though both will be much easier on the ears shooting in a blind.

My advice is to focus more on the application being used for, if you plan on shooting heavy slugs go with the LSS, if you are deer hunting and shooting lighter slugs the LS provides plenty of fps and fpe plus has the added benefit of allowing hunting from tree stands etc 

I just ordered the Texan LSS in 45 due to rules in my state requiring 45 for hunting deer. I will get some dB numbers up when it arrives this week. In comparison my Benj Bulldog 357, with the Mega Moderator attached, the lowest I have measured is 113dB at the breech. I suspect the LSS will be similar but it wouldn't surprise me if the LSS is in the 120-130bdB range due to the design. All said and done, it's not quiet but significantly better than a non-subsonic 22 rifle (let alone any larger rifle calibers for conventional rifles). 

I am trying to figure out a way to describe the loudness of the .45 LSS but I think you will like it. 

Some tips, get a bipod or good shooting sticks, it is long and nose heavy 

I almost always use Hunters Supply for my loads https://hunters-supply.com/air-454-cal-250-php-p-1443.html These 250 gr are perfect all around loads that I use.

The new Texan has a different valve system Never dry fire your Texan when it is empty of air or you will knock the valve into your tank. When you get your gun if it is empty you will need to stand the gun upright and cock it to fill it the first time also you will need to pull the valve forward.

The 45 is a air hungry gun so make sure you have a large source of air you will need it, from my experience ( with 4 different Texans) it takes a good 40 to 50 shots to start getting it tuned and learning its power curve. I will tell you that all of my .45 Texans the power curve sweet spot is at about 2800 psi with the 250 gr bullet. I run the fine tune at about 75%. 

Another Word to the wise the moderator in the lss shunts the air back and through the whole tube all the way back into the trigger system this has caused some problems because no one realizes that the lead dust etc is being shunted that far back and it builds up. I have taken to using a green brillo pad wrapped around inside the tube to act as sort of a filter to help stop the dust from going that far but even so it will need to be cleaned 

As an update the dB for my LSS with a 405gr is 109



Not Bad!
