I'm one step closer towards my goal for high power tuning. I added some preload tension to the spring and have it up to 951fps with 34gr MKI's (68FPE). I bought a bunch of the 34.7gr NSAs to test out. They seem a little tight inside my barrel, and they're coming out at 935fps. I should be able to squeeze more out of it, I'm still a ways below 160bar right now.
The 33gr VKs might shoot a little better with the added power. They're coming out around 945fps on the high side, so there some room to tune for them. They didn't seem to have enough umph behind them when I tested last weekend with 880-905fps.
