I did get a chance to shoot the trail boss and 2495 loads last weekend. I didn't shoot much as my chronograph did not work the entire shooting session.
I can say that the trail boss will not cycle the action even at a full load, but it may help it be a super quiet load suppressed. I really think that the Accurate 2495 will work for what I am doing. I really don't know what they were pushing fps wise, but even my 80% loading cycled the action. Quick load calculates that a 28.2gr load would put me right at 1100fps, witch will work in my location(never freezes here, so even at that speed should stay subsonic). the 2495 was not as dirty as I had thought it would be, and I have no problems with the bolt hanging like I had with 4831.
I got my ced millennium2 chronograph today so it the hurricane doesn't rain us out, I'll get more data this weekend. I also finally sent my form 1 paperwork to the BATFE and hope that it doesn't take a year for them to get to it. Once I get my tax stamp, I'll start working on the suppressor.
