- #Ok, so I have this new Browning Hi-Power Practical (the 2-tone model)

- #Bullseye). Retiring the Inglis to the safe, should I use a weaker
- #recoil spring in the new Hi-Power, or pull the bullets and reload
- #more powerful loads?

- #The other interesting thing is that I made a batch of ammo with 3.8gr

- #source min max load

- #Speer 3.5 3.8
- #Hornady 4.1 4.4
- #Hercules 4.9

- #(all loads for 124gr lead bullets & Bullseye powder)
- #I've been told I need to produce around 1100fps for IPSC in 9mm
- #which (according to the books) looks like a minimum of 4.4 grains.

- to change springs. If they do not cycle, a weaker spring may help.

- As far as the loads you mention: I believe that you will have a hard
-
- time finding data for lead bullets at over 1000 FPS. The Speer "max"
- load you listed is only good for 962 FPS, while a 124 grain jacketed
- bullet can take up to 5 grains of B~ullseye for 1148 FPS. These loads
- are for Speer bullets - swaged lead that does not do well over 1000 FPS.
- They deposit too much lead on the barrel at higher velocity.
-
- Get some good hard lead bullets (or plated, or jacketed) and you can
- get more velocity. For IPSC your 124 grain bullet will need to go at leeast
- 1010 FPS, plus a little more to be sure; I use a 147 grain bullet at
- 1050 FPS for extra help on the knock-down targets.
