I again have access to a range again so hopefully I don’t have to travel this year for work and can again do some experiments starting in Spring.
Long story short in order to get needed velocity say from a 200gr bullet like the 200FTX I see no other option other than going with a duplex. For me I want to use a single vial with double compartments. For single loads I like the plastic vials that allows me to see the powder and that it is all emptied when poured. The point of the double compartment is to keep the whole load in one location instead of having 2-loose vials to deal with.
Now this poly plastic doesn’t lend itself to gluing so I thought I would try fusing the ends with carefully placed heat from a soldering iron. Surprisingly it worked well and when I tried to flex it, it held together without breaking. With the use of this method there is a groove left behind from the pointed soldering iron that I don’t like having.
I tried to produce an epoxy band around the joint but the epoxy ran and had to quickly clean it before it solidified. Okay no panic as this can be corrected by rotating the vial while the epoxy cures. Years ago I used to build fishing rods and after tying on the eyes the thread had to be coated with epoxy. For rotation I used to use a barbecue rotisserie motor and may have to build another that would be a nice winter project anyway.
One way or the other I will have that epoxy band for additional support. Anyway I thought I would share my project and to where I’m at with it.
