here's an easy way to test for leaks in the breech area. it can test for leaks in the bolt seal & transfer port seal & alignment. it can also give you an idea on how good the probe is seating the pellet.
1) get a piece of 1/4" plastic tubing, the one for a refrigerator ice maker.
2) heat till slightly soft, then pull to stretch it. what you're looking for is the tube forming a cone that will fit into the barrel. then trim the excess.
3) insert the cone into the end of the barrel & blow into the tube. with a good seal, no air should be leaking from the breech area.
load a pellet & unlock the bolt. blow into the tube & this will give you an idea of the pellet seating. air leaking...bad. no air leaking..good.
i tried this on my new 2100b & it leaks big time. well another project.....
Not a bad idea. :-*
Interesting concept,99. Baby powder or flour is quicker for me.
That is actually a good idea. :)
Can learn a couple of things there :-*
Now to find some tubing.
Nifty idea. Not as messy as the powders but how affective?

i figured this test will catch the obvious leaks. the powder or flour can catch the high pressure leaks.
an example....
on my 1377 with the stock bolt--
bolt locked no pellet, no air leaking.
bolt lock with pellet, no air leaking.
bolt not locket after seating pellet, plenty leaking. on closer examination through the breech, i see that the pellet is only half way past the transfer port. oh well another thing to mod, a bolt with a longer probe.
great idea!

Now you are catching on to why the to-do list just keeps getting longer and longer. :)
