Baer45 Posted July 15, 2012 Share Posted July 15, 2012 I bought some of these to try for first time in a Baer 1911 and was disappointed with no grouping. Tried them over 4.2 and 4.4 of TG. Loaded them a little long. I wondered if since they are .356 they might be better in 38 Super then in 9 mm Luger...next step would be to drop down to 4.0 or try different powder... Any ideas greatly appreciated...C Link to comment Share on other sites More sharing options...
rhyrlik Posted July 15, 2012 Share Posted July 15, 2012 What I ususlly do with FMJRN is start with a given powder charge at 1.170" OAL and reduce in .020" increments until I get the accuracy. You could try 1.170", 1.150" and 1.130" with 4grs of TG to start. Then, try 4.2, and 4.4grs. Sort your brass and try different primers. Bell the case mouth minimally and don't crimp. Just remove the bell. If you overcrimp plated bullets you ruin accuracy. I choose not to crimp at all, relying on case tension to hold the bullet. 9mm's seldom have setback issues.

Cheesewhiz Posted July 17, 2012 Share Posted July 17, 2012 (edited) I've had very good results with Berry's 124gr HBRN over 4.5 to 4.6 of HP-38/231, I load them at 1.165" OAL. Mine are shot out of mostly stock barreled CZ's. My taper crimp is just a kiss. Edited July 17, 2012 by Cheesewhiz Link to comment Share on other sites More sharing options...
Baer45 Posted July 18, 2012 Author Share Posted July 18, 2012 Thanks! This is real helpful. I have given up on TG and thought I would try a slower powder next....C Link to comment Share on other sites More sharing options...
