1. Marauder (Totally stock. The only mod I've made was to the lawyer spring).
2. .177
3. Fill Pressure 3000 PSI (Hill Pump)
4. 30 (will do 40 before dropping off, but I only have 3 mags for the moment. I typically refill after I've shot the third mag.)
5. End Pressure: 2500 PSI (after 30 shots). 2300 PSI (after 40 shots)
Need to double check settings as some minor tweaks were made to the hammer spring and throw adjustments. I started at 1.5 CW on the hammer spring (from fully CCW). and about 2.5 (from fully CCW) on stroke. Metering screw is at 2 CCW (this is verified). But I have made some adjustments (probably an additional 1-1.5 turns in on the spring and possibly in a bit more on the stroke - sorry I don't have these figures yet - I started watching the chrony and not recording my adjustments. I am a noob). This tune is getting JSB Exact 10.34gr to move at a peak of 920 FPS (looking like a fairly repeatable 895-920-890 over about 40 shots according to the crony).
Yesterday, I shot a horsefly that landed on my target at 30 yards. Accuracy is outstanding on this rifle!
Gen 1 .177 Marauder. All stock, lawyer spring removed.
