AZ, I haven't gotten to that point yet, I've only had the gun a week, maybe Frank has a better idea since he's experimented with the Programmer, or Bobby since he's been involved with the Red Wolf gun for a couple of years. I do think it is possible to get it to the under 5 FPS category (as I did with my .30 Bobcat), but would take much experimenting with all the variables available on the Programmer. I know my Bleu Wolf with a stock factory setting in Medium shoots right at an ES of 7 or 8 for 30 shots from 250 to 205 bar. This equates to about 0.2 MOA elevation variance at 100 yards with the RD Monster pellets. I'm also not sure what the "baseline" pressure is that the gun works off of, or why the speed drops as the bottle pressure lowers past 205 bar.
This is the issue that has been solved with the Delta Wolf. The Delta has a Huma regulated Plenum, so that the electronics in the gun have a consistent pressure to base their settings off of. Combine that with a built in chronometer, which feeds the speed back into the action loop for shots, and I can see an ES of 1 or 2 FPS as routine. The Delta platform is the logical progression from the Red Wolf platform, and is a revolutionary increase in airgun technology. Whereas most guns trundle along with evolutionary changes and improvements, this Delta leapfrogged current airgun technology and is a revolution in precision and performance.
You might say that the mechanical systems with long and tedious tuning by a skilled craftsman can do the same, and you'd be correct. I've gotten my .30 Vulcan2 to shoot with an ES of 3 FPS over a 20 shot string. I've seen posts of Impacts that do the same, but I'm not sure if they were Keyboard or real guns. However, think of this. I tune my gun for 975 FPS with the RD Monsters. I'm in San Diego at near sea level. Then I go to my horse ranch permission in Descanso, which is 3500 ft. elevation and cooler. Humidity is less. Will my mechanical gun shoot 975 FPS? The answer is empirically no, it won't. It might be more, it might be less, but it won't be the same, The Delta on the other hand is programmed for 975 FPS. A few shots and the gun adjusts speed to where you have it set. Or I want my gun to be spot on for the Precision Marksman Challenge at RMAC in Provo, Utah. I have my range card set, but its based on a specific speed for my gun, say 855 FPS with .30 JSB Exact. I did the range card and testing in Temecula, CA (approx 1,000 ft. elevation) at LDs range. Now I'm in Provo at 4500 ft. elevation and its much cooler. My range card, especially at the longer ranges (PMC is 20 to 105 yards) is no good… With the Delta, its spot on, no worries.
Technology moves forward, and doesn't wait. Initially the "old stuff" may outperform or equal the "new stuff". But not for very long. Think vinyl album versus CD, points and plugs vs. electronic ignition, tube vs. LCD screen TVs, and the list goes on. The Red Wolf was the start, and can be equaled with mechanical technology. But the Delta is a leap forward and no mechanical system can equal that precision over a wide range of shooting conditions IMHO.
