Very good point, while I've shot PCP's I don't yet own one, and I'll definitely consider picking up a disco. How much do you think I could get one used with a pump for?
Bob summed it up pretty well.My first attempt was a blind shot in the dark. Lots of fiddling to get minimal returns. Now days when I get the urge to tinker the Discovery and Marauder platforms are where I start. The "hard part" is already done. ie trigger, stock, air tube and fill port. The valve has been "started"and with a few tweaks can produce enough power. A little barrel work and a new breach, you are ready to go.I will be picking up a disco soon for such a project. I have an Mrod due to arrive today for the same reasons.If I had the time I would probably try a scratch built again at this point. I have learned a lot from the posts by rsterne and lloyd on this sight (search for posts they have started).It also depends on when yo want to go coyote hunting. I went just this morning. I use my Dragon Slayer .50. It is nice to have something ready to go out of the box instead of waiting to finish a project before I can enjoy my other hobby.Since you need a pump anyway (assuming from your post above) a disco combo would be a great setup to get started with. I started out with a used Benjamin hand pump. Converted my 2260 to PCP. Then I purchased the Dragon Slayer used (took an 8 point buck it's first season).Good luck and post pictures, whichever option you choose.
