Mike,Exactly at what shot are you coming off reg? I see a slight bump up after shot 32 and was wondering if that was it.Also, how many shots on the front end are attributed to the 200psi overfill?Thx.
Lol I've done that before but it was due to too small of a gap on my ssg, a 2600-3k dump shot, I've had em fly from 845-868 (done it 2 or 3 times) when you dump it...the first time I did it I was actually looking thru the scope and it almost gave me a black eye!865 fps on a first shot is a good sign...Hope you come back with a 860-870 string! That would be awesome.
Do you remember what vavle spring you used? All I can find is very light.
Whats the rating on your hammer spring? Kind of curious is you were able to go with a much lighter spring on this setup.
Is the weight of your hammer w/o the bolt and spring, I assume? Really 5 mags a fill at that power, is fantastic. I will be setting up one of my .25's to try to match it.
Decided I couldn't leave it alone just yet.I made a spare hammer, decided I would see what adding more de-bounce properties to it would have on the latest string.I drilled and tapped 8 holes on the back of the hammer. The holes are drilled to within .250" of the front face (each hole can be partially filled with lead shot then sealed with set screw).Has anyone tried this (can tell me if this is a waste of time)? I won't have time until the weekend to install and get a test string.
Quote from: shorty on October 11, 2016, 05:44:07 PMMike,I am thinking you can get more out of it in regards to FPE and shot count. My goal is 50+ shots at 40 fpe using an 1800 psi reg setting. The difference between ours is the porting which allows a lower pressure to be used for the same power level.Since you have a Hill valve in there ( I think he uses .16"exit on the valve ) you can change out the transfer port sleeve and drill the barrel to matching .16" porting. In theory, your efficiency should go up at your current reg setting and same 40 fpe power level.No need to pull out the valve. Everything is after the valve.For example,My .196" porting through and through can hit 38 fpe at 1100 psi where at .14" porting it will only achieve 18fpe/24 fpe. In theory, when I come off regulation at 1800 psi, I should get a small bell curve opening the ES slightly greater than 2.5%. I am doing this on purpose because there is a balance between shot count and power levels when using a regulator. I want to have a really high efficiency 40 fpe 25 cal but still be able to hit 50+fpe with somewhat of a shot count (30+ shots-plus reg drop off).So to answer your question in my opinion, yes, you should be able to squeeze out more shots at that power level.Although,You do (as of right now) have the best regulated 25 cal marauder that I have read about. I have to recap this one so everyone understands how your getting nearly 40 FPE with nearly 50 shots regulated using a 25 cal marauder.Buy a 25 marauder - 400 to 500 bucksInstall an after market valve - 120 to 150 bucks ( do it yourself - 10 bucks for drill bits)Install a huma reg (gauge port style) - 120 to 150 bucksRun an SSG - 80 bucks or soRun a light weight hammer - 50 bucks or soTotal:840 bucks.Set reg to 2200 psi and let her rip.I for one do not know of any off the shelf 25 cal that can be had at that price with the power level and shot count. Completely impressed with this platform. When it comes to tuning pcp's, I'm learning as I go (tons of info out there I need to sit and marinade in).I still have a lot to learn, and nowhere near as much knowledge as most members on here.But from what I do know I agree more can be obtained from my tune, (more of a gut feeling than an educated one honestly).Thanks for the TP input.....looks like I'll be pulling breech off tonight! I'll post back results later tonight.Thanks Shorty!!!* my Huma gauge port reg was $112.27 shipped to my door direct from Huma in the Netherlands.* SSG spring used was the heavy spring that came with the first version WAR SSG (at that time it came with two springs).
