Wanted Posted March 5, 2009 Share Posted March 5, 2009 Ok, I have some 230gr. lead truncated bullets. these are homemade by a guy. I can't find any published data im my manuals or on line. Now I set the OAL at 1.25, nope, wouldn't chamber. I re-seated to 1.20, chambered fine, headspace looks good. So now I'm looking at load data. I averaged out the lightetest I could find for that weight bullet. Unique 5.2 gr 231 4.5 gr TG 4.2 gr Any thoughts? Link to comment Share on other sites More sharing options...

Wanted Posted March 5, 2009 Author Share Posted March 5, 2009 (edited) Kimber Custom II, When I took the barrel out and dropped one in the chamber it was above the top maybe a couple of hundredths . Let me clarify. I'm not using proper termanology. Not headspace, but when I do a drop test test in the removed barrel, they fit good and are flush with the hood.

Ray R. Posted March 5, 2009 Share Posted March 5, 2009 wanted, I never had a 45acp that wouldn't chamber a round if the rounds fit in the magazine. Still, its possible that the barrel is short chambered. However, if the rounds drop in the chamber when you check them with the barrel out of the gun they should work, unless you have a feeding problem. Are you taper crimping? Bkeeler's load data is good for Clays, although you can use data for a 230 gr cast round nose bullets for the 230 grain truncated bullets. Generally speaking, it takes 3.7 to 3.8 grains of Clays to make major with a 230 cast bullet. With WW 231 you might need 4.7 to 4.8 grains. All depends on the particular gun....

mwx40x40 Posted March 6, 2009 Share Posted March 6, 2009 Trunacated Cone Profile seats shorter than same weight Round Nose. I least that is what I have experienced. Maybe others with chime in along these same lines. Link to comment Share on other sites More sharing options...
Hany Posted March 14, 2009 Share Posted March 14, 2009 (edited) Trunacated Cone Profile seats shorter than same weight Round Nose. Thats been my experience too, sounds like your chamber might be on the short side...but then again I guess mine was too. 1.200 should serve fine.

Wanted Posted March 14, 2009 Author Share Posted March 14, 2009 I did get around to shooting some of these. OAL was 1.200, I used Win231 and Unique. The loads with 5.4 grns. of Unique were the ones I liked best. No function problems, accurate and less smoke. Link to comment Share on other sites More sharing options...

z40acp Posted March 15, 2009 Share Posted March 15, 2009 I had some bullets I bought from Penn Bullet. They were 230 gr. TC, the OAL I used was 1.215". You could probably go to their website and see if yours have the same profile. Link to comment Share on other sites More sharing options...

ChristopherG Posted March 15, 2009 Share Posted March 15, 2009 I too am using a home-grown cast 230 LTC. I loaded them to 1.200 because that appeared to be SOP from a mix of manuals and bullets, though I didn't have data specific to the LTC. Haven't had any feed or reliability issues in my CQB. 3.7 Clays makes major very comfortably (and I've been doing my chrono-ing at 25-30 degrees f.) and with good accuracy.

technetium-99m Posted March 25, 2009 Share Posted March 25, 2009 I shoot a 220 gr TC from a Lee mold. I load em to 1.205 with 5.3 gr Unique and a CCI 350 primer. Makes 170 PF. Great load. GT Link to comment Share on other sites More sharing options...
Wanted Posted March 25, 2009 Author Share Posted March 25, 2009 Thanks, I made a bunch with 5.4 grains of Unique. They shoot well, I appreciate the PF info. Link to comment Share on other sites More sharing options...
8ring Posted March 25, 2009 Share Posted March 25, 2009 The bearing surface of the truncated cone bullet is longer than on a round nose bullet. Hence, they must be loaded shorter to fully seat. My powder recommendations are 3.7 to 3.9gr Clays, 3.7 to 3.9gr N-310, 4.2 to 4.4 gr American Select or Winchester Super Target. These powders all work well with lead.

Patrick Sweeney Posted March 25, 2009 Share Posted March 25, 2009 Truncated cone bullets are not loaded to the same length as other bullets of the same weight. You determine the correct length for that particular bullet by seating it such that the edge of the shoulder is just barely past the mouth of the case. Exactly as you load an H&G 68, so the lead shoulder just "shields" the case mouth from the feed ramp. Whatever that length is, it is. If, at that length the bullet does not feed well, then you either abandon using that bullet, or you get the gun worked on. No other choices. As for powder, the classic advice applies: start low, work up, use a chronograph. Link to comment Share on other sites More sharing options...
