Dwbsig Posted September 2, 2018 Share Posted September 2, 2018 (edited) This may not mean anything to other sig owners but I slugged one of my barrels on a full size p-320 and it slugged at .3563 so I started using.357 bullets in it got better Es and sd#'s with some improvement with accuracy.

This. when i changed to .357 135gr bullets my groups got better and SD/ES improved SIGnificantly. I also have a cleaner barrel than i did even shooting .356. I see no reason to shoot anything else.

Do you know the PF. @Dasniper X5, Manufactured april this year. 3.5 Titegroup, 1.135 OAL. 1093 avg FPS, ES 5, SD 2 from same headstamp brass, 5 shot string. after those numbers i didn't feel the need to keep going. this puts me @147 power factor, which is higher than most like. But it is super consistent and super accurate with this recipe. i could probably play with OAL and drop to 3.4 or 3.3 and drop that some, but don't feel the need to. With this load the gun cycles fast, and is not snappy, i can very easily keep the 6MOA romeo dot in the window with this. Also the .357 show land/groove marks clearly on recovered lead, the .356 was super light but visible. Edit: For the record i shoot this out of mixed brass for matches, i only sort by headstamp for load development to reduce variables. Edited September 7, 2018 by DsWright adding brass info.

3guns Posted October 4, 2018 Share Posted October 4, 2018 Here is my load data for 125 gr Blue Bullets Link to comment Share on other sites More sharing options...
JAFO Posted October 5, 2018 Share Posted October 5, 2018 I'm assuming you guys are all talking about 320 X5's. I don't have one of those, but here's my data for an X5 Allround with a barrel that slugged to 0.3565": 125gr Blue Bullet (0.356") 3.6gr Titegroup 1.08" OAL (I load short so they also fit my wife's PPQ) Winchester WSP Mixed Brass 20 rounds Avg Vel = 1056 fps ES = 38 Sd = 8 PF = 132 Before I started using the Blue Bullets, I was using Ibejihead 124gr at 0.357". I had asked Nathan at Blue Bullets whether he recommended I use their 0.355" 9mm/.38 Super, or their 0.358" .38/.357 bullets, since my barrel slugged to 0.3565". He recommended sticking with the 9mm. For comparison, here is the load data for the Ibejiheads: 124gr Ibejihead (0.357") 3.6gr Titegroup 1.08" OAL Federal #100 SPP Mixed Brass 20 rounds Avg Vel = 1067 ES = 55 Sd = 12 PF = 132 Link to comment Share on other sites More sharing options...

Aircooled6racer Posted July 30, 2019 Share Posted July 30, 2019 Hello: My P320X5 did not like the blue bullets for accuracy so I switched to 147 Acme bullets which it did not like also. I am shooting 135 Acme and the accuracy is much better. Going to try some Gallant 125's this week. I am also going to load back out to 1.135-1.140" OAL as well. I have been loading to 1.115" and having zero problems with my reloads. Thanks, Eric Link to comment Share on other sites More sharing options...

Southpaw320 Posted August 6, 2019 Share Posted August 6, 2019 I’ve been messing around with the Brazos Precision bullets. The above was with 1.14 oal and 3.3 grains of Sport Pistol out of my X5. Link to comment Share on other sites More sharing options...
