You are probably correct. It's been a while since we've done a Vortex and out of habit I just equate black to soft (thinking Bully, H'man, etc.)I would think Silver Springs maybe the second hole. Black are pretty stiff springs for that low of engagement.

I agree with the silver spring second hole. It’s 160 rpm difference for each hole you move the spring into. The tighter you pull the spring back the quicker it engages.I would think Silver Springs maybe the second hole. Black are pretty stiff springs for that low of engagement.
