Crosman air pistol - General discussion / Re: Chronographs
« Last post by Rualert on January 16, 2021, 08:24:21 PM » Hello all, I know it's been a while. That said I didn't see specific mention of using the F1 and a simple USB cable available from a couple of sources which allows the use of both commercial and open source free software to capture shot string data in basic csv and other formats. I have been using this setup for several years with no complaints. I will add that I use one of Brutz's spreadsheets modified to FPS rather than MPS to record data, calculate averages and built usable graphs.
Just something that might be of help.
Glad to be back for at least some interaction as I have been so berried I have not had time to participate, which I apologize for.
Casey

1377s have so much potential but are so held back by our legal requirements. Is your 5.6ft lbs with 10 pumps?

Looks like your having fun.

Crosman air pistol - General discussion / My 1377
« Last post by Fzrandy on January 14, 2021, 09:17:29 PM »Hi all....First post here 
....
Got my 1377 a couple of months back as always liked them and quite liked the idea of having a pistol that can be converted into a carbine rifle and back again so set about working on it ...
Firstly was a bit underwhelmed with the power only 3.2 ft/lb 415 fps after 10 pumps. Was kind of expecting that as it's a c model ...So after stripping and cleaning I drilled and tapped the bleed off on the valve and fitted a M3 grubscrew next I drilled out the transfer port...While I Was doing the internals I ordered a steel breech and extended probe ...Once it arrived I re assembled and tested over the chronograph which was vastly improved but sadly illegal in my country ...So took apart and made and fitted a slightly smaller transfer port which left me with 5.6 Ft/lb 550 fps very happy with that
Tried the Crosman stock but discovered that couldn't get a good eye alignment with the scope so made a quick detach stock from an old telescopic walking pole and a motorcycle footrest (slightly unusual combo I know ) but with a few mins on the lathe I had it fitting nicely and is easily removed and fitted by just by twisting half a turn ....So very happy so far some better grips is next on the agenda
