The SWC run fine in my Uberti 1860 Henry ....no problems with feeding at all ..
it`s the post I`ve seen in the last few years about rounds going off in a mag tube that bothered me ...( I don`t want anything but a flat nose against a primmer ) ,,,, but hey thats probally just me .
I`ve had to seat them deep in my pistol rounds because the point will jam up the cylinder if they aren`t seated deep enough ...( on my 45 `s I have to seat all the way to the top of the flat part , with only the dimple exposed and crimp there)
They seemed more trouble than they were worth for me , I shot up what I had and now stay with RNFP in rifle and pistol .
