Then they are in need of work.
I found it easier just not to use XTP's.
Then they are in need of work.
I carry and run 3"/4.25" and 5" 1911's. They will feed everything I have fed them. I prefer HST over any load, but it is not a magic bullet. Shot placement is far more important. GD, TAP and Ranger is also carry preferred carry ammo. I love Hornaday, but prefer to stay clear of the CD and tactical CD line... I prefer 230gr loads... period. I have had over 20 high end 1911's as well as low/mid end RIA's, mil-specs and a few others. I have never had a 1911 not feed any ammo I put in it. I also run a couple hundred rounds to ensure reliability and then get a case or two so I can trade out my carry ammo every several months.
So you are buying up all the ammo!
Remington Golden Saber always work for me.
They used to be easy to find.
Best advice is to feed it what the owner manual tells you to.
