Problems loading 9mm berry's 124 flatnose

[kmw1954]

Western Powders has data listed for each powder in 9mm using either the Berry's RN flat base or the HBFP.

I have also had discussions with many reloaders about the Berry's Hollow Base and the Flat Base. From everyone I have talked with it is generally agreed that even though the Hollow Base is over-all longer they still displace the same volume inside the case.

Western suggests a length of 1.060" for the HBFP.

I use the 1.055" length for both my FB and HB loading because I need that to plunk my XD..

Honestly I've never measured them, all my pistols are semi-auto's, I remove the barrel from the gun when setting up the dies for my Dillon and check how the ammunition drops into the chamber adjusting both the depth and crimp.
How the ammunition fits in the gun you're shooting it in is the deciding factor on such adjustments to your dies. Individual chamber, case, bullet and die dimensions all effect how a reloader sets his dies.
There's to many variables in the equation to give exact measurement to someone else with assurance it will work for them.

But you offered a charge weight and a velocity. That's useless without knowing what you use for the C.O.A.L.

How the ammunition fits a particular gun is not a deciding factor for me. I have three 1911s in carry rotation, and several others that see recreational and/or competition use. It would be silly for me to tune my ammunition to just one of them, since that could exclude several others. I need my ammunition to fire through any gun I put it in. If that results in a bit of extra bullet jump in some of them ... so be it.

For some reason many people don't approach loading handgun and shotgun ammunition with the same attention to detail as rifle ammunition.
There's no problem with loading one ammunition for several different firearms but your going to have to test each one individually to see if it fits in the chamber and magazine and loading them closer to starting loads would be prudent as well.
I offered 4.0gr. of universal because it's about the minimum that will cycle a 9mm 100% of the time, it happens to be about 1000fps from my gun. I wouldn't call that useless information, most reloaders are surely aware that every gun will have a different average velocity because barrel length, rifling type etc etc.
You have to get out of that mindset that loading for a handgun is different than loading for a rifle.
