The coil density is consistent over the full length of the spring. I've seen some that pack more coils in the middle or at the ends. Does that help identify the type?

Thanks very much for the replies guys. Yeah I should be more specific. Gun clocked at 385 as bought. I've tried taking a small amount off the spring which took it to 375, but tbh not very happy with the job I did. It's tricky to pinch the spring back to give a flat turn at the end with the tools I have, hence I want to try just buying a new spring. I don't know what the standard spring is (can post a pic of it helps). I believe it is a v3 gbx

Hi, Can anyone please recommend a spring to downgrade a Beta project Sterling to 350fps? Cheers Tom
