Winchester 1977XS Velocity and Accuracy Testing
https://www.youtube.com/watch?v=3ICwl3hXNvU
Today I performed velocity and accuracy testing with some interesting results on a Winchester 1977XS .177 caliber pellet rifle. Let's see if this gun can hit the manufacturer's claimed 1000 FPS.

The above vid isn't mine and the guy shooting isn't me. I posted it so ya'll can get a general idea of how the Winnie 1977XS performs.
The Winchester1977XS: amounts to a souped up Daisy 880 w/ a different stock. The Daisy 880 gets approximately 656 fps / 7.6 fpe w/ 7.9 gr .177 pellets & 10 pumps. The 1977XS gets 838 fps / 12.3 fpe w/ 7.9 gr .177 pellets & 10 pumps.
I've had mine since January, 2021. I ordered it from Academy for $69.95. Initially, I popped off a couple of shots w/ 5 pumps. WOW! That 7# stock trigger may be the worst 'lawyer proof' trigger I've ever seen.
Aside from the trigger, I liked it. Shoulders nice. It didn't come w/ an owners manual. I downloaded a manual for it from Pyramid Air.
At first I low mounted a Tasco 3-7X20 on it instead of the high mount 4X32 it came w/. Using Daisy wadcutters I sighted in at 10 yards and the last groups fired (using 3 pumps) were 0.5 inch in size.
Half inch groups at 10 yards w/ an unmodified trigger. I figured I'd keep it. *Smiles*
Since then, I've been modding it. Filled up the hollow buttstock w/ silicone caulk. Which made it balance a LOT better and made it feel more solid at 4 lbs of weight.
I took it apart & did the CC shim trigger fix & removed the flat spring. I can definitely agree w/ Joseph Lewis' (aka JL's) opinion of reassembly of the trigger group being 'the tricky part'. No freaking kidding it was the 'tricky part'.
Anyway, got it back together w/ no extra parts laying around. Heh.
Tried it out. The folks that say the 1977XS trigger is still stiff after trigger mods know what they're talking about. Trigger pull is around 5#'s now. It's not nearly as bad as it was. The safety still works. That's good, I guess.
'Not being as bad as it was' isn't exactly a glowing recommendation though. I imagine a few hundred shots from now it will have eased up a bit.
I got some heat foam tape to quiet the CLACK sound when pumping. I also removed the lower latch spring. Pumps quiet now.
Acquired a LDC from Geo Schoonmaker for it. A shot at 10 pumps will sound like a shot w/ 3 pumps Which is quiet. Shooting it w/ 3 pumps at 566 fps w/ Daisy 7.87 wadcutter/flatheads, which is what I usually do for nailing hosps, sounds like I'm spitting. The LDC also steadies the barrel the same way the duct tape barrel fix does for the Daisy 880.
I also made a slice from a foam ear plug, made a rectangle out of it and superglued the rectangle to the slot in the chamber for BB's. W/ out that mod, pellets can get into the BB magazine when rolled into the chamber. I also bought cross action tweezers from Amazon so I could precisely place the pellet in the chamber. Lastly, I acquired a .177 pellet pen from Air Venturi and made a scabbard to hold the pen and the tweezers on the stock using duct tape.
After modding it, I changed the scope to a Barska 4X32AO w/ mil dots and sighted it in for 25 yards.
Best performance can be had w/ Crosman 10.5 gr at 15 pumps which yields 810 fps /15.2 fpe. 10 pumps w/ that same pellet is good for 745 fps and 12.9 fpe.
5 pumps w/ Daisy 7.87 yields 655 fps / 7.5 fpe and 5 pumps w/ RWS 8.3 gives 660 fps / 8.03 fpe. Both pellets give 1 inch groups at 25 yards.
This 1977XS might well become my favorite air rifle. Lightweight at 4 lbs w/ scope, accurate, powerful and the trigger mods are easing that trigger up nicely.
