I'm shooting a dreamline tac .25/600 w double plenum, huma reg, hi flo dual hole to... I just swapped for the new slug barrel liner 1:16-600.
I so far am extremely impressed by how well it stabilizes and packs the Slugs tightly from 850-930 . I just today finished testing and I'm going to stick with 2 slugs. 30gr zan .250 or 30gr Griffin LDC .250. They're leaving the barrel at 915 now, however they were packing them in a bit tighter of a group @ 847-852... And that's where my incredible 25.39 tune was set, I just slapped in the slug liner and shot at my pellet tune, increasing the power wheel to figure out a velocity. Should I revert back to that setting and start adding reg pressure and compensating hammer spring tension for the increased pressure? Or should I just go back and use the things at 850?
My "peak/perfect" pellet tune was 120bar, 13pw. just a c*** hair shy of 3 turns on the 1.5 internal hammer screw, with a velocity of 905 SD of 3 and ES of 9. Getting just over 100 shots per 500cc. 250-150
It just doesn't sound as good shooting the heavier slugs at this setting and definitely not when I increase the wheel. 7 steps to get 917~ fps.
Obviously 30gr at 845-850 is still going to have a better energy and velocity retention than pellets and higher velocity past 30y and on.
Am I wasting my time if I go up to 135-140? Or should I just stick it at the current reg and internals and just use the wheel to compensate?
