Thanks Ming. I appreciate all of the detail there. I checked my spring and it seems to be the thicker wire but maybe it's the short spring instead of the original full length one? It's hard to say the length without removing the spring from the assembly. I'll plan on shooting a larger variety of shells through my 1301 Comp when ammo supply becomes reasonable again. Until then I'll lean on the Win AA 1200FPS stuff I've got on hand to carry me through any matches in the next few months. Thanks!

Sorry for the necro bump here. BravoKilo, did you ever get your 1301 Comp figured out? I am having similar problems with light loads failing to cycle. I started off with the heavy stuff to break it in and it seems pickier about light loads than I would have expected based off all of the stellar reviews online etc. Here was my progression: Federal 1600 fps slugs - 25 or so cycled fine Rio heavy target 1 1/8oz 1250fps - 125 out of 125 cycled fine Fiocchi low recoil slug - tried 15 or so and about 10 failed to cycle Remington STS 1 1/8oz 1150fps - mostly fine - ran 200 or so without memorable problems Remington Gun Club 1 1/8oz 1150fps - maybe 60 out of 75 attempts failed to cycle a new shell into the chamber after firing - gave up and have the rest of a case left Winchester AA 1 1/8ox 1200fps - so far 25 out of 25 cycled fine. If the others aren't consistent I'll keep running these at matches until they let me down
