I have several.. Two in .22-250, two in .243 Winchester, two AR's, on in 5.56 and another in 6.8 SPC. I suppose that would be about six.
I've tried out many more but have now settled on using my AR's and my stainless synthetic .22-250. One of my .243's is also stainless synthetic, but it's a featherweight and I don't shoot it as well as my sporter weight bolt rifles, so it stays home mostly.
