fellas I am looking to pick up a 44mag uberti 1873 lever gun with some 44 spec brass. Looking to load some red dot I have with speer 200 grain GDHP, which is about the best expander at low speed. I keep hearing about 'blowback' though. For lower powered loadings, what does this mean? A little gas in the face( which wouldnt bother me) or inconsistent ballistics( which would bother me)?
