Springfieldxd

Good Idea...Gonna be a real pain with 600 rounds though. I would check for pressure signs at shorter OAL's first and go from there. I'm sure you have some that gradually step down from your original 1.150" Say something around 1.125 then 1.100 and so on. If not....you can load some up at various OAL's and determine the shortest you wish to go. Those rounds that are too short..........well you gotta get to work.

If it were me....I would would measure each round and start Shooting the longest OAL you have and work my way down to the shortest. Check for pressure signs as you go.

I've used this bullet with CFE-Pistol in my XD 9 mod 2. OAL was 1.050 with 5.2gr CFE Pistol. I use the same amount of CFE Pistol in my 124 RN bullets with an OAL of 1.135. Velocity's were pretty close to each other. The HBFP-TP bullet is .534" long compared to the RN @ .585" Difference of .051" So If you seated the RN at 1.150 OAL and seated the HBFP-TP at 1.099 OAL you would have the same amount of bullet inside the case. The Hollow Back would also allow for more case volume. Load up those HBFP-TP with the OAL you need to Pass the plunk test and start at the minimum powder drop for W231 which I believe is 3.9 gr. (double check me on that) and work up some loads. You shouldn't have any issues.

I have a Springfield xd 9 and it is similar to the cz's with needing to load shorter with Hp's and flat points. Especially Berry's Target hp's and HBFP-TP. I have both bullets but I don't have any good data yet on the Target HP. Will be working on that in the spring. I checked my data for the HBFP-TP which is pretty close to the Target HP. Sorry Nothing with Titegroup yet. Berry's HBFP-TP 124 gr. 5.2 gr CFE Pistol OAL 1.050 1098 fps I did a plunk test with the Berry's Target HP and it just clears the lands at 1.072. I would probably load them at the same oal as the HBFP-TP @ 1.050 If you're bullet is just clearing at 1.070 you should reduce that another .015 to .020 so you should be loading at 1.050 to 1.055. Your bullets hitting the feed ramp are another issue. If they don't chamber at the proper oal you need to consider a different bullet.
