I have let many people fire it along with my M1 Garand, or any mil surp I bring to the range. I always bring some extra ammo, so someone else can try out a different weapon.
My 1941 Johnson, is my favorite, maybe cause it usually draws some people over, over all it is just a great shooting rifle. Followed by my 30-40 Krag due to how smooth it is.
It isn't super secure but check out the ( Swisher ESP Safety Shelter ) it is made and sold as a shelter for tornados. They come in sizes from 6 person up to 25.
It is on Camp Perry the OHIO National Guard base, there are 1000 yard ranges there. But you can't use them sadly. If you go in July the national CMP matches are going on, tons of vendors there.
