  1. A buddy I shoot with has feed issues with his XD's as well, both an XDS and an XDM. His just don't like Xtreme FP's but they feed Xtreme RN's without a problem Everyone seems to think this is mainly a 1911 problem but mine, an Remington R1 and a Springfield Mil Spec, will eat anything I have ever fed to them Why they use water in grains is a very simple way to measure the volume inside an irregular shape. The old school way I heard of doing this yourself is to seat a bullet in an empty case with no primer. Weigh it on your scale. Use a syringe to fill the empty case through the primer fl
  2. About #2 COL is nothing more than an external measurement of a finished cartridge. Seat depth is determined by what will run in your gun or possibly other factors such as trying to increase pressures or even reduce the powder charge and still maintain the same pressures/velocity. Bullet shape is the primary determining factor of COL. I doubt there is a gun out there that will use the same COL for all bullet types. About #3... Every load manual I have or have data from (Sierra, Hornady, Speer, Nosler, Western Powder, Vihta Vouri, Alliant etc ) all mention specific bullets by brand in the
  3. It's not really a perception, you are loading to different OAL. OAL is only an external measurement. Just because you didn't have to change the die set up doesn't mean it is the same OAL. But glad things worked out for you...
  4. Chris I feed nothing but FP's to my 1911's, feed problems were all related to OAL. I load them extremely short (for a 45 anyways) and this solved my feed issues. Doing so may or may not work with a 9mm 1911...
  5. You need to know the length of the bullets themselves. Get out your dial calipers and measure the length of one of each, RN and the FN, and they must be the same weight bullets. The difference in length is how much difference there needs to be in the OAL to maintain the same volume inside the case. The shorter bullet needs a shorter OAL to match the chamber volume of the longer bullet. That way you can use data for a RN when you don't have data for an FN. But the data is only valid for the same weight bullets. If for some reason your FN and RN's have the same length of just the bullet y
  6. This is exactly why I get ticked at the load manuals when they do not include actual length of just the bullet. Provided the loaded cartridge will feed, chamber and cycle in your gun it doesn't care how long or short it is. The important thing is just how big the volume is inside the loaded case. And as you know this is determined by the OAL and the length of the bullet itself, so to use the data from a RN you need the length of just the bullet So provided you are using the same bullet material (lead, plated or fmj) loading a FP (yes some makers do call them flat points) to an OAL that is
