craig2724 Posted February 26, 2010 Share Posted February 26, 2010 I am trying to work up a load for 9mm. The problem is that I am trying to keep the recoil to a minimum and keep the power factor up to 125,000 (velocityxbullet weight) per IDPA rules. I don't have a chrony so I was hoping that maybe someone had velocity data to help me out. I am loading 4.0 grains titegroup and 115 grain Berry's plated bullets with a COL of 1.110. The gun I am using for competition is a Springfield XD with a 4" barrel. The Hodgen site says that it should be around 1075 fps. Does anybody have any tested data? I realize it will vary with the gun you are using. Link to comment Share on other sites More sharing options...
bkeeler Posted February 26, 2010 Share Posted February 26, 2010 Every gun is different you need to chrono for accurate info. Link to comment Share on other sites More sharing options...
rstandley Posted February 26, 2010 Share Posted February 26, 2010 You should be just over the power factor with that load. Link to comment Share on other sites More sharing options...
freakshow10mm Posted February 26, 2010 Share Posted February 26, 2010 Well, a 115gr at 1075 is only 123 PF. Have to step it up a bit, not much. Take the actual charge divided by the max charge and multiply that by the max velocity. That's about what a generic gun will get in same length barrel. Example 4.1/4.3 and multiply that by 1151 to get 1097fps approx. So 115gr at that fps will get you a tad over your PF at 126 PF. I'm sure your range or someone there will have a chronograph and let you shoot through it. Link to comment Share on other sites More sharing options...
xcelr8n Posted February 26, 2010 Share Posted February 26, 2010 Titegroup is temperature sensitive too. I wouldn't take any chances trying to stay close to 125PF without a chrono. Split the difference between starting and max load until you get a chrono. [Reloading is dangerous. You could blow your head off. xcelr8n is not liable for opinions posted] Link to comment Share on other sites More sharing options...

Duane Thomas Posted February 26, 2010 Share Posted February 26, 2010 In 9mm, recoil really shouldn't be a problem. Factory standard pressure 9mm tends to go in the 135-140 power factor range, and is hardly an abusive load to fire. A lot of people who reload 9mm - I'm one of them - forego the "just barely make power factor" approach and load to the factory equivalent 135-140 range just because (1) recoil is still so light there's no reason not to, while simultaneously (2) this really takes the worry out of the chrono station.

RH45 Posted February 26, 2010 Share Posted February 26, 2010 The few guys I know that were using 115 grain bullets with Titegroup were running 4.4 grains. I run 4 grains of Titegroup with a 125 grain, jhp. Link to comment Share on other sites More sharing options...
jailer252 Posted March 12, 2010 Share Posted March 12, 2010 For IDPA I have been using Berry's 147's over 3.4 of universal clays. Nice soft shooting. Thumps down steel pretty good. I am now experimenting with BBI 147's over 3.2 of solo 1000. (thanks to many forum members for this new load) The BBI are very economical and right now out of my 34 with factory barrel they are 134pf. Good luck, welcome, and enjoy.

Also you may want to consider a higher PF, as some guns (M&P) can get finicky below 130PF. The time you loose shooting 135PF vs 128PF is negligible. The time you lose because you gun does not go into battery or you have a double feed... is several seconds per. Link to comment Share on other sites More sharing options...
Aircooled6racer Posted March 12, 2010 Share Posted March 12, 2010 Hello: If you want a soft load use some Precision moly 147 grain bullets loaded with 3.1 grains of Tite Group and a 1.140" OAL. That should be about 126PF in your pistol. Thanks, Eric Link to comment Share on other sites More sharing options...
RePete Posted March 15, 2010 Share Posted March 15, 2010 The 2 powders I use for 9mm are VV N320 and Unique but I use 147gr CMJ bullets. Link to comment Share on other sites More sharing options...
