Hi. Interesting work. I have a question for you, here in Sweden, we are restricted to 10J on our rifles, by installing a valve pin, we can go back to the 57J that (bullboss) is made for, beside changing the valve pin, is there anything else needed to change? hammer spring or anything else? is just changing the valve all one needs? my .25 with 10 J is so weak it cant even penetrate a Pepsi bottle at 15 meters...
First of all great video! but I didn't understand everything because I don't speak fluent English, can you tell me if the mechanism is identical to the flashpup s? if yes how to unclamp it by changing the needle (without drilling it) because I can't find this piece on the internet.
I currently own a AT 44 and I am very much impressed with your tutorial. How similar is this approach with the flash to that of the the AT 44 Thank you in advance
From what I've compared to other owners is that it may very, but should be around 40 FPE give or take at 850fps with JSB 25gr.. mine is strictly for hunting so No concern with shot count, JSB 34gr I'm making around 54FPE....
Yes. I’ll be ordering one next week. For the main purpose of hunting and occasional back yard shooting. I have a large back yard n no neighbors so it’s safe shooting. I am just curious n wanting to know as much as I can. I hope to get as much power out of it as as I can without matching the parts as I don’t have the needed equipment. I shoot from a tree stand only about 15-20 yards. Just wanting to dump as much energy as I can at that range.
My Flashpup was of excellent quality in machining and parts, but to be honest I don't own every entry level rifle so it would be unfair to comment on other rifles.... but any company mass producing any product will have some slip by with not so good quality products and I have read and talked to owners with this complaint from all differant air rifle owners of different manufacturers...owners on air rifle sits on Facebook give good feedback on different air rifles about the good and bad about the rifle they own..
Hi brother i have a kral puncher jumbo gun and i want to increase the velocity of this gun this time this gun gives 790 fps on jsb 25.33 grian how i can increase the velocity upto 850 or 870 can i change the hammer spring or full tight the original hammer spring
Yes, since it's not regulated you would just have to adjust the hammer Spring say quarter turn at a time shooting over a chrony until you get your desired FPS...
Unfortunately this was one reason why I have not picked one up yet, They do have issues with the valve pin breaking... You may want to upgrade to a new pin before attempting more power , or have it already purchased and see what happens with this one....
Hi, IM thinking of doing the port job at my flash 22cal , what do you think abaut that, is it worth it, and can you covertt your mesurment on the drillsize in metric.
I would watch the videos I did on my Hatsan flash 25 Cal being tuned... I have all the results of my tuning on the videos, and I am hoping to be posting another video on my flash pup for the results of all my tuning
