Sheepdawg,
With a few things working against me, I will answer your questions to the best of my ability...
First things first, chronograph. I was able to get readings on the first 14 shots, 3 of which were my sighters for OCW. I can only assume that the lighting is my biggest problem but I will share the info that I do have:
36.5gn 1)2187 fps 37gn 1)2058 37.5 1)2041 38 1)2230 38.5 1)2197
2)2078 fps 2)1988 2)2108 2)2024
3)1977 fps 3)2104
(shot in a string so do not have avg, spread, or s.d, as all 14 shots we under 1 group and I haven't done the math yet.. sorry)
when I shot the 38.5 (2) and 39 I got nothing but errors and blanks also. So, there is my chrony info, such as it is.
As for the rest of your questions, please excuse any ignorance as this is my first time loading straight wall cartridge in a semi auto platform. My focus since I started reloading has been directed to my bolt action high velocity cartridges; 25-06, 240weatherby, and .204ruger to name a few of my recent works. However, pressure signs I assume remain the same, to which I find nothing all the way thru 39gn. (which is only.5 grain above max for a 250gn bullet in the ramshot loading manual). So, to answer how the brass looks (other than any pressure signs) and how the recoil is, I can only compare to hornady factory ammo loaded with same bullet (250gn ftx) and say that is very comparable.
Gas operation and ejection..? I will say that all rounds cycled flawlessly. I do not see any "heavy" marks on the rim of casing from the extractor.
And finally, does it burn clean.. again, with only have factory to compare to at this point, It looks like the fouling around mouth of case are the same as factory. have not had a chance to clean barrel so I will have take a closer look at that but again nothing noticeably different.
I am going to pick up some magnum primers next time I get a chance to. Other that trying the 39 again and possibly toying with seating depth, a primer change was on my list of things to try to tighten that group up a little.
Thanks for interest!
