First off I purchased a Dream Tac Compact from Scott.t on here and I can't thank him enough, great guy and great deal.
Here are a few of the observations I have since putting a several hundred rounds through this rifle.
First, the mechanical.. I like the idea of total adjustability, but I have to admit, I'm the type of shooter that tunes a gun for a purpose and generally leaves it alone. For me, the Royale is the best FX rifle made, hammer, reg and xfer port are all adjustable. But, this DT is fun in it's way.
Second, the trigger, with so much technology going into FX rifles, it escapes me that they don't redesign the trigger. It's not bad per se, it's just not up to the guns. Every FX has basically the same trigger with the exception of the Boss, and that trigger is a monstrosity to install and tune, but it's a step in the right direction. I suppose this is nit picking because the trigger is quite useable, and can be tuned some, so it's not a big gripe.
The action is outstanding, as all FX rifles are, smooth and functions perfectly, this is where FX shines. They did come up with a much, MUCH improved magazine, which is perfection personified! This little dandy is just the right weight, not too light, and certainly not too heavy, with a scope of the compact 3-12X persuasion, it is wonderful. One thing FX got really right, was the comb to pic rail height. If you've shot a Notos, you have experienced the other end of the spectrum. With the Notos I need super high rings, and it is just kind of strange, but the DT has a raised pic rail and a lowered comb and it is perfect.
Enough comments, I have questions.
Let me preface this with I totally understand the problem with such a short barrel and a cf 300cc bottle. You're simply not going to get a hundred shots in the 900 fps range, it ain't happening. By the way, my original post on this subject was when my chrony crapped and I got some amazing results for this rifle, but my new ProChrony proves a much lower fps. But still, I keep thinking that mid 800 fps with 18gr pellets, and somthing on the order of 40-50 shots is not out of range.
1) There's not a lot online that I could find about tunes. I started with 18.1gr FX pellets, and accuracy was fantastic, top notch, but velocity was low from what I could find online. I'm having trouble getting even 750 fps. It is low 700s.
I moved to any other 16gr pellets and the speed is up of course, but accuracy is meehh, 2-3 moa, or worse. It turns out the turbulence from the short barrel at max output is too much for light pellets. I tune it down a bit, get 750fps , with just over 100 bar reg, and 4 hammer, and accuracy with lighter pellets is equal to 18 gr pellets, fantastic. BUT, online I did find two tunes, that got well over 800 fps with 16gr???
If I move the reg to lets say 140 bar, then air useage goes well off the charts, and I don't get the velocity gain you would expect. So it seems here I'm running out of barrel?
I have my reg at just over 100 bar now, and am getting the 16gr 750fps and good shot count.
My thought is to increase the reg, cut back the hammer and start increasing the hammer til it doesn't show much increase and see where I go velocity and accuracy wise. This is the only real tune I could find online and it gave 840-860fps.
One more note, I can't feel much resistance when chambering a pellet, so I'm going to try and see if maybe the breech seal needs replaced, but I'm doubting it, because, my 750fps tune with 16gr pellets, produced a 28 shot string, with 9fps ES, so looks good there, but it is possible, it leaks aboud the seal, consistently, I've seen it happen, and a short barrel lessens the effect somewhat.
Any thoughts from the FX gurus?
