I've got a Barnes Expander MZ (non lead) stuck in a Green Mountain LRH barrel 1:28 twist made for sabots and conicals. This is on an old Investarm Hawken not a modern inline ML. :-(
Please help me come up with ideas on how to get this unstuck.
This is how we got here:
Prior to loading I fired two percussion caps to clear the bore. That's just what I was taught to do before the first load of the day. In hind sight, I wish I'd run a patch in there, but hind sight is 20/20.
I loaded 75 grains of Pyrodex RS (yes, I'm 100% sure!) and then the Expander MZ. It was definitely a snug fit but it wasn't as if I had to hammer it into the bore. It's fully seated on the powder at the bottom of the bore. It's probably worth mentioning that I've never tried the Expander MZ before.
A dozen caps later with various attempts to clear the nipple (it was clear) etc, I still couldn't get the power charge to fire. My assumption at this point is that I must have had a bit of oil or something at the bottom of the barrel bore. This rifle had been in storage for a few years and I foolishly didn't check.
I tried using a CO2 unloader three times and it didn't shift the sabot even slightly. Granted the fit of the unloader isn't 100% so I may have better luck if I can resolve the little bit of leak. I've used the unloader before on lead ball and it worked fine.
My ball extractor screw won't penetrate the copper(?) Expander MZ so that method out.
The breach plug has never been out of this barrel and isn't interested in coming out easily. Perhaps a long soak in a penetrating oil would get me there. I don't know.
I was contemplating trying the large size Speedout screw extractor on an extension to engage the hollow point and pull it about 1". If I can get it out of the sabot it should be relatively easy to deal with the rest.
I was also contemplating making a custom nipple like thing to give me a leak free connection to either the CO2 unloader again or just go straight to a full CO2 bottle.
What options am I forgetting about? Keep in mind that there is 75 grains of powder in there so anything with flame or heat from drilling is right out.
thanks.
