Wow, even a Nelson Q40 isn't as fast as a West .50 with an APC 8x10, that'll take it to 200 according to the box. But wait, my Demon only did about 170-175 with the West .50 running about 21k on an 8.875x9.25 and open pipe..so the only conclusion is that the Demon is slower than the Magnum R and the DD. And yet, for 6 years people have been telling me how much faster their Demons are. Oh yeah, and I pulled my West out of a Magnum R and dropped it into my first Demon, and it was way faster. The difference was significant, many who knew the Magnum commented on it. No wonder I get confused.
