The Flounder-- wow +/- 4 using co2?? Have you tried using hpa yet or do you prefer co2 for some reason. I believe Trinity posted on his blog that his SR1 was getting +/- 2 or 3. Pretty impressive results so far from the CCM rifle. My only concern with the SR1 so far is the reload time and the shells ejecting. I could probably modify a small canvas bag with hinge to catch the shells and that can be flipped foward (so the shells dont fall out) for reloading.
