I have several 1911 in 9mm and am going to reload some self defense rounds for them .I could use some help in what direction to go with as far as bullet type and powder to get a reliable cartridge for feed and function in an 1911
The O.A.L. can be critical, and needs to be watched. The interior space of a 9mm case is very small, and if the projectile is seated too deep the pressures can escalate rapidly. A change of mfg. from one 124 to a different 124 needs to be worked up separately as nose dimensions could be different enough to cause it to seat deeper or shallower, and alter the ballistics. Find your preferred bullet and stay with it, and check the OAL often.
Yep, and check with a plunk test. I now have 4, 9mm pistols and the plunk test in one worked for the others, except my new gun. Got a new pistol and first range trip I discovered my "Just in Case" ammo didn't work in my new Masada. My JIC ammo is my standard load I keep on hand for emergencies, grab and go. I have about 1,000 rounds sitting next to my 9mm Ruger. Checking my ammo I discovered the Masada chamber is a hair short for the particular bullet in my JIC ammo...Make sure your bullet will feed in your gun. I have some that will feed in my Sigs, but not Smiths. Most HP's that have a sort of round nose look to them will work.
