I just installed my level 10 on my classic valve mag last night. When i turn the velocity up to get it close to where it should be (i'm hoping for a solid 280 fps) it bleeds air out of the back of the valve. I've called myself reading all the literature i can get my hands on but can't figure out what i'm doing wrong. Help!?
I'm using the biggest carrier in my kit. question here
The kit i got was still factory sealed the paper label had never been broken but it only came with 5 different carriers. In the directions with the kit one place says it should come with 9 carriers and like 1 paragraph later it says kits should come with 5 carriers. Which is correct?
So my level 10 is largest carrier from the set of 5 that came with it, the gold spring, and 2 shims.
Today at the field it was shooting right about 250 fps if i turned the velocity up any higher it started bleeding air out of the back of the valve. What do i need to do to get the FPS in the right range without it bleeding out the valve the whole game?
