Guys, the issues with insurance companies is quite real. We've had our fun with them in the N-SSA. To get coverage, regulations are getting tighter and often to those of us with long experience, somewhat onerous. But this is the legal climate we live in. For example, CCI used to make the very best musket caps, hands down. Then an idiot reenactor with a drilled out nipple and too much powder got a cap fragment in the eye and sued CCI. Presto, no more good caps. CCI reduced the power in the musket caps to the point to where they're only suitable for blanks.
So while we moan and complain, the changes are often driven by lawyers and insurance carriers who don't care about your stinky old guns. Those same lawyers and insurance companies are often 2A hostile.
Shop for another insurance carrier? That would be great except for the fact that you can count the number of national carriers on one hand, missing a couple fingers, who will insure active shooting range activities. Couple that with commercial liability and the number grows smaller. This is a symptom of a greater problem.
