Just finished another round of fettling, chrono’d the SA-E04 with its original spring (310 FPS), M100 (308 FPS) and M110 (380 FPS), both courtesy of @ak2m4

 

Dremelled 2 coils off the 110, then another half a coil and ended up with 338 to 340 FPS. Flattened and finished the cut end and will let it bed in for a few thousand BB’s.

 

Will keep the 310 springs and use them to push some heavier .28 or .3’s and see what happens.

 

All ready for tomorrow, might be a bit muddy after today’s rain, better than the heat though that’s for sure.
