    … i'd take the gamble and get a .22 asp20 with the whiskey3 scope they offered with it initially….  sooner or later , you'll find a $300 used hw 77 or 97…..i found an older hw77 carbine for less than $300 , and it had that larger diameter tube from the 80's or 90's or whatever…..wish i had kept that longer , but i didnt like underlevers then….  ag's of az has the .177 diana 430L underlevers on for $199 now , i got mine a month ago when they were $230 w/out scope and zr mount , but now i wish i had just paid the $270 for the gun,scope, and mount….   that gun is in the closet until it COOLS OFF here in ft.worth …   ag's of az told me to send in the one-piece diana lockdown mount they tossed in after they explained they were out of those scopes and mounts now, and it was gun only….but just got an email from darren telling to send that older mount back in for the new zr 'slider' mount…..    my buddy anthony found a .22 hw77 full length for under $300 somewhere (pawn shop ?)….  and he LOVES his more than his walther lgu's …. but i betcha he still likes his .22 air arms pro-elite better than the older hw77 , and the 820 fps pro-elite would be a very close comparison (size, weight and power, anyway) to the newly released .22 sig asp20 in beech stock….  these gas strut / piston guns are not very 'tuneable' , tho … we can put lighter springs or heavier tar inside the hw97's to smooth them out…..   if you're shooting field target get the expensive hw97 (in 5mm with laminate stock even) …  but if youre killin stuff , the sig …   i cant believe golenstateairgunner's story with sig cust service !!  …he really put that .22 asp20 he got when they were first available through the ringer , man .  . . .   but now he gets these numbers ??    that's like a .22 diana 460 , man !!    { Now it shoots 13.3 gr Wraith alloy pellets at 890 fps in warm weather. The Sig Crux lead pellets at 14.7 gr average 860 fps. I was pleased with Sigs Customer Service Dept. }    – keep bending lead !!    – paul 

     

     

    "  i cant believe golenstateairgunner's story with sig cust service !! "

    When I sent mine back the turn around time was 2 weeks. It was 28 total days from the time I shipped it FedEx and the day it arrived back at my doorstep. Of course, that was nearly 5 months ago. Maybe they are more busy now. The bottom line is it's not a story. It's fact. 😉

    As far as velocities go. I've really been dabbling in how temperatures effect velocity of the Sig. My findings probably hold true for any gas-spring airgun. I use a FLIR temperature gun and take readings of the receiver tube before chronograph testing.  Some results.

    Gun temperature  68 deg

    Sig Crux alloy 9.6gr.   1055 fps

    Sig Wraith alloy 13.3gr.   884 fps

    Gun temperature   82 deg

    Sig Crux alloy 9.6gr.   1066 fps

    Sig Wraith alloy 13.3gr.  887 fps

    The light Crux alloy pellets are really affected with higher temperatures while heavier pellets see less gains. The highest Crux alloy velocity I've had was 1077 fps. The most efficient ( weight to velocity ratio ) pellet in my Sig is the Crux lead. These pellets weighed at 15gr get 850 fps in warm weather. The same pellet weighed at 14.7gr. gave me 859 fps the other day in warm weather. The Crux leads have been the worse as far as being advertised weight. The Crux is listed as 14.66gr but 60-70% of them weigh 15 to 15.3gr. They are very accurate and efficient in the Sig though. Plus, I'm nearly at the 24 ft lb mark with the Crux lead.

    Just a follow-up to my Sig Sauer customer service episode described in previous posts. The rifle was returned 6 weeks to the day of initial shipment. The gunsmith’s notes indicate that a “vibra-tite/locktite”like material was applied to the first stage trigger travel Allen screw necessary to keep it from moving during operation. I shot approximately 40 pellets through the rifle and find the problem solved. So, other than the long wait, I’m satisfied with the repair. 

    Interesting ! Wonder if Sig is going to apply Loctite at the factory before they get to the sales shelf? 

    Perhaps so, I’m not sure. That said, As I understand it, Vibra-Tite remains pliable after installation, which allows screw adjustments if necessary. As long as my trigger travel remains fixed, I’m happy. 

    I just shot 20 Sig Wraith 12.35 grain alloy pellets across my crony. The results show an average velocity of 866 FPS, good for about 20 fpe  I consider the rifle accuracy superb at 50 yds. According to ChairGun,  the pellet energy delivered at 50 yds is about 12 fpe. That’s not bad. 

    One point about the Wraith alloy. They are listed at 12.35 gr. I haven't seen any lighter than 13.2 gr in two separate tins. Most (90%) of mine weigh 13.3 gr. This was proven on a OHaus Triple Beam scale as well as my digital reloading scale.  Likewise, Sig lists the Crux alloy pellet as 10.05 gr but 99% of mine weigh 9.6 gr. I haven't had one weigh 10 gr. What was the temperature and what elevation are you at when you did the chrony test ?

    I’m at about 500 feet above sea level and the outside temp was 83 degrees.

    I'm at 80 ft above sea level.  At 550 ft your losses are minor. Do you shallow or deep seating the Wraith pellets ?

    I use a pencil with an eraser on the end to seat my pellets. The pellet skirt ends up flush with the breech face. It’s a tight fit. Yes, I’m satisfied with the energy generated by the rifle. It’s about 22% more than my HW97K.

    That's about how I seat mine as well. Flush, or just barely above the breech face. Deep enough though where they don't distort when closing the barrel. In Tom Gaylords review of the Sig ASP20 he achieved better accuracy deep seating the Wraith alloy pellet. I've noted some velocity loss deep seating but not much. I've also been using my pellet sizer and die set that I made. Some pellets I gain velocity while others lose. The die of choice is the .218" and really helps with velocity of the Wraith alloy pellet. Like anywhere from 20 to 23 fps increase with better shot consistency. The Crux lead pellet loses some velocity after sizing.  Here is the sizer I made. I have four different dies.   .215"  .217"  .218"  .220"

    That’s an impressive Pellet sizer. Looks professional.

    I did some machining work as part of my career. I did a little testing today with H&N Field Trophy pellets. They weighed between 14.7 and 14.8 gr.  Rifle receiver temperature was 78 deg. Averaged 852 fps. Gun seemed to be shooting a little low today. Who knows why ???
