Looking for something to do this year

Where can I get a .40 fast  twist bullet barrel. I'm thinking about another underhammer rifle build and the Pedersoli Gibbs is not in my budget

These days my observation is most club members don't want to or are afraid to compete.  Local club has a shoot every Wednesday night during the warm months when I joined 20 years ago there would be 20+ plus shooters now there is 6.  Most of them won't compete at the state level with the WMLA.  And those shoots have fewer participants every year.

As far as the youth are concerned most of them want immediate gratification, can't be separated from their phones and are always bored no matter where they are.  At the last team match someone brought their grandson to the state match and all he did was play with his phone.  More than one attempt was made to draw him out but was wasted effort.

Sorry to sound negative but in the last 20 years fewer clubs and shooters.

Now that I have a .45 bullet shooter I'm thinking of building a .32 bullet shooter us in a #2/#3 32-40 barrel from Green Mountain mounted on a Allen underhammer action this should make for an interesting 200yard rifle and great for prairie dogs and groundhogs  any thoughts on what I should use for a bullet and mold thanks

Found this site and looks like fun.  Just finished a Allan foundry underhammer in .45 with a fast twist GM barrel will be taking it out tomorrow for first time I've mounted an old Weaver k4 scope I built this for my own amusement not sure it can be used in any match except for WI inline shoot but oh well.  I am curious about sealed ignition using rifle primers is there a source or info I plan on building another Allan underhammer using this system thanks
