Better feeding in a .45 with semi hollow point??
Strange but true, regarding my older .45cal AMT! Although I have had great success with new style mags., such as Tripp and Wilson, the Hornaby critical defense ammo chambers, fires and ejects essentially 100% of the time even with a stock mag. Now this gun is very finicky and like many .45s was designed to fire ball type ammo. Other internet posts note that most problems with the AMT are failure to fully lock into battery. I figure that it somehow lilkes the more traditional bullet shape of the Hornaby round over the bulbous shape of the standard ball ammo. What do you think? Thanks!

Maybe, but I'm struggling with what physical changes make a gun ball or more JHP friendly.
On shorter stroke guns a bullets profile and the shells OAL can mean a lot to feeding. I'm thinking bringing calipers and measuring OAL would be best. The just buy the shortest. Shorter will feed faster...Although, depending on the gun, because some guns are over spring and need slowed down...I.e. longer OAL. |

What year is the Amt?
For those made in the 80's and up, were modified to feed HP ammo.
Normally, the feed ramp is polished to insure that the surface has no imperfections to retard the HP moving up the ramp face. Then the edges of the chamber are "broke/ relieved" to act as a "funnel" that the hp round won't hang-up on. There's plenty of information regarding this procedures, that you could attempy or find a good .45 smith to handle it. |

I can't speak for the AMT pistol, but it's been my experience that nothing feeds more reliably in a semi-auto pistol than hardball (fmj) ammunition.

Unless the ammo shortage has forced you to buy somekind of knock-off brand, it's is HORNADY.

Sometimes you just have to go "old school".
My USGI 1911a1 don't care what you feed it. It just keeps going and going. And I've loaded some real junk trying to find out what it doesn't like. My Series 70 Gold Cup is the same way. I just use cheap old GI magazines in both.
