deerslayer Posted January 7, 2011 Share Posted January 7, 2011 I'm trying to achieve 750 fps with a 230 FMJ. So far, 4.9 grains resulted in ~625 fps. 5.2 resulted in almost 700 fps. These velocities are MUCH lower than I expected. I plan to bump it up to 5.6 grains, which is pretty close to max. Do any of you have any load data and chronograph results data for Winchester 231 with 230 grain bullets? Link to comment Share on other sites More sharing options...
lugnut Posted January 7, 2011 Share Posted January 7, 2011 Not sure what gun you are using but here are my results with my G21SF- G21SF, 230gr Berrys, 5.4gr W231, Fed Primer, 1.260" COL- Ave 782 ft/s I thought I ran another test with same load/gun and the speeds were a tad higher but I can't find them. I've gone up to 5.8gr and one of my manuals has 6.2gr max. My 1911 results were slower than same loads in the Glock. Link to comment Share on other sites More sharing options...

CHARLES D Posted January 7, 2011 Share Posted January 7, 2011 I loaded 5.3 of 231. results 173 p.f--754 fps. The results were shot from my Kimber. However, I think the bullets only weighed 228 grains (Zero) Link to comment Share on other sites More sharing options...
deerslayer Posted January 8, 2011 Author Share Posted January 8, 2011 Gun is a Colt Lightweight Commander. I also tried the first 4.9 loads in a friend's 5" Baer and got about 30 more fps. I am shooting Precision Delta 230 FMJs at 1.26 OAL. Hodgdon/Winchester website says 4.2 min, 5.3 max. That is with a 230 FMJ FP loaded to 1.20. Sierra book says 4.9 min, 5.7 max w/ 230 FMJ at 1.27. Between the two, I thought 4.9 would be a good place to start. I think I'll try 5.6 tomorrow. Thanks for all replies. Link to comment Share on other sites More sharing options...
Emerson Posted January 10, 2011 Share Posted January 10, 2011 I load 5.4gr of HP-38(231) with a Precision Delta 230 FMJ. Link to comment Share on other sites More sharing options...
jdewberr Posted January 14, 2011 Share Posted January 14, 2011 @Emerson, What is your OAL & crimp? -- Joe Link to comment Share on other sites More sharing options...
RH45 Posted January 15, 2011 Share Posted January 15, 2011 Hmm, when I used 231, I ran 5.1 grains behind a Zero 230 fmj for 750 fps out of my 5" Les Baer. Link to comment Share on other sites More sharing options...
