Hi Everyone,

Been working on this with Mike the builder since January. It is now up her in canada.

I roughly used the B50/Datsate huntsmaster as a place to start but the whole gun was made from scatch except the trigger group. It is from a b50.

-28" .30 LW Airgun Blank (will give about a 26.5" barrel compared to the 18.5" stock barrel)
-Riser Breech
-Big tube 1 3/4"od (1 1/4" id) .... 8" longer than stock.
-Boyds stock


The stock for comparison is a b50 stock


































we needed more flow through the valve


The hammer


we were not without breakage... this was a valve that did not hold up


Mike did some testing using the gun int eh vice as I had the stock here for finishing



(20:03:51) bluesdaddy: 86gr 900
(20:04:42) bluesdaddy: 68gr 965 to 1065
(20:05:01) bluesdaddy: backed off to 950
(20:05:31) bluesdaddy: getting about 20 good shots with 68s
(20:10:11) bluesdaddy: velocity stays up above 875

To summarize!!!!
154FPE with 86gr @ 900fps
171FPE with 68gr @ 1065fps
136FPE with 68gr @ 950fps

He also tried some 55 grain Mr Hollow points and did 175 FPE with them but were not accurite. First tune was 50.15 Daystate Emporer at 950 fps. Mike was hitting paitballs at 100 yards with it!

Got thinkgs up here from the USA into Canada



Unfortunately shipping was not to kind to us.





I repaired the broken trigger group.. drilling new holes and taping for 8-32 screws. Also had to modify the screws to fit.



the gun did nto have a trigger guard so I made one




I did not like the raw look so I flame blued the trigger guard and stainlees screws. The steel took the blue much carker than the stainless as expected.




This is the Gun befofe lame blueing the trigger guard.. but scope on and ready for action.



Hope to get air soon.. My tank is out for hydro :( I will do a full report on performace once I get the kinks iron'd out!
