Quick Draw McGraw Posted December 29, 2010 Share Posted December 29, 2010 Looking for Zero 230gr FMJ loads for my SIG GSR XO 1911. Does not like EXTREME plated bullets. Currently use Titegroup, Unique, & HP38 for powders. Thanks, Bob. Link to comment Share on other sites More sharing options...
DougCarden Posted December 29, 2010 Share Posted December 29, 2010 4.0 grains of CLAYS with a 230 is hard to beat.... DougC Link to comment Share on other sites More sharing options...

DougCarden Posted December 29, 2010 Share Posted December 29, 2010 With the ogive on the 230 Zero I load to 1.230. You should make up a couple dummy rounds, start at 1.250 and chamber it, and make sure it will fit in the chamber, then extract and eject out ok. Once you find what you like, then tighten up your seater stem, set the crimp at .468-9, and go to town.... Good Luck, DougC Link to comment Share on other sites More sharing options...

Good Luck, DougC Doug, Any chrono numbers on the short aol 1.230 , I have been running mine 1.255, I noticed that most 45s feed well in the 1.25-1.255 range. I have been reluctant to go shorter fearing high pressures. My shortest load is with a 185 HBRN at 1.240. Link to comment Share on other sites More sharing options...
pjb45 Posted December 29, 2010 Share Posted December 29, 2010 (edited) hmm, I thought the 45 ACP was a low pressure round? Additionally, was the 1911 designed for a 1.2 AOL. If you load your ammo too long some magazines will not function reliably. The angle of the follower can decrease thus putting the bullet in a more perpendicular angle to the front and back wall of the magazines causing friction which can result in FTF or stoppages. Bottom line is many guns run very well with a 1.2 AOL. Minimum SAAMI is 1.19 - I believe Edited December 29, 2010 by pjb45 Link to comment Share on other sites More sharing options...
DougCarden Posted December 29, 2010 Share Posted December 29, 2010 In my guns, 4.2gr CLAYS with Fed primer at 1.230OAL in my Revo is around 740ish, and in my 5in .45s it runs around 760 ish. Hope this helps.... DougC Link to comment Share on other sites More sharing options...
Aircooled6racer Posted December 30, 2010 Share Posted December 30, 2010 Hello: I load to 1.230" and started that since the Kimber I had at the time would not take anything longer with Precision moly bullets. My load is 3.9 grains Clays and 230 grain Precisions with Winchester WLP primers in a 5" 1911. Thanks, Eric Link to comment Share on other sites More sharing options...
fastarget Posted December 30, 2010 Share Posted December 30, 2010 (edited) Well, I am in agreement with you all then,,,,I was reading all these posts with people loading to 1.275.... Ok, I have loaded some RN bullets before to 1.265, and they functioned ok, not consistent in my kimber, so so in the nighthawk, and not well in my Baer/SVI. Reading The wilson combat insert from a magazine package, it recommended 1.250......so I started shortening the oal......found that 1.250-1.255 ran beautifully. All the guns were cycling 1.250 100%. Then I get gifted 5K of 185 HBRN, and I went down to 1.240 or a bit less looking for a practice round to use all these bullets , cycled fine, needed a bit more powder (I was running 4.3 clays), accuracy was good, but was not sure how far to go and be safe.....the 1.235-1.240 for the HBRN was dictated by the end of the shank as max insertion limit.

DougCarden Posted December 30, 2010 Share Posted December 30, 2010 Nope, you are on the right track. Might I also suggest using a little more taper crimp? Try some ammo with the .468 crimp, then try some down at .462 and see if your group tightens up..... 4.5 or so should get you around 140-150PF that should function your 5in guns as well..... Good luck, DougC Link to comment Share on other sites More sharing options...
planenut Posted December 30, 2010 Share Posted December 30, 2010 (edited) I see you have Titegroup. I made some 230 Zero FMJ with Titegroup and got the following results from a Colt Commander 4.25" barrel, PMC Brass 4.4 Titegroup, WLP, 1.265 OAL, 734FPS High, 700FPS low, 710fps avg, 24FPS ES, 7FPS SD 4.66 Titegroup, WLP, 1.265 OAL, 765FPS High, 743FPS LOW, 753FPS avg, 22FPS ES, 6FPS SD I only fired about 20 rounds of each and plan on doing more at 4.5 grains of titegroup and shortening up the OAL after reading this thread. Hope this helps. Edited December 30, 2010 by planenut Link to comment Share on other sites More sharing options...
Quick Draw McGraw Posted December 31, 2010 Author Share Posted December 31, 2010 Thanks for all the responses. I too have reduced my COAL to 1.250 -1.255 and voila my SIGruns much better. Loaded the Zero's to my usual 1.26 at first and noticed the ones that didn't feed had little dents in the bullet nose. Reduced the OAL and problems went away.
