Efficiency vs Consistency, and Setting Your Regs for Both
I've noticed something about my B2K4 and I'm wondering if there are any suggestions whereby I can acheive both efficiency and consistency.
With my current setup, it runs most Consistent at 220psi and adjusting the LPR to get ~275fps. However, it's not very efficient.
When I set the HPR to 250-260psi (for better efficiency) and then try to adjust the LPR to get 275fps, my consistency goes out the window..... it's jumping from 240-280fps.
I've lubed up everything and I've lightly polished the ram housing and ram shaft and hammer.
