Does anyone have a low fill pressure of 150 bar at the start of there sweet spot.it looks like I do..I filled to 190 bar and was getting 10.3ftlb for around 20 shots..I decided to dry fire down to 150 bar and chrono again and started getting 11.4ftlbs.ill have to do a chrono test starting at 150 bar to see how many shots I get in the sweet spot...I didn’t think a s410 would be has low has a 150 bar fill for the start of the sweet spot

First off you're not going by the gun gauge are you? if you are testing it's always better to leave the gun connected to the bottle so you're using it's more accurate gauge. How do you know the sweet spot starts at 150 (by the gun gauge) if you've dry fired it down to that? most find it's more like 170. You need to start your chrono testing at 180-190 to find out where the true sweet spot is. No need to do every shot every 5 or so would do and use the bottle gauge to make it a more accurate test.
