coldchar Posted June 1, 2012 Share Posted June 1, 2012 Just a heads up, trying to make major with Titegroup in 45 will be an exercise in erratic readings. Try Clays or another powder. Titegroup requires a lot of left over case capacity to be consistent. Jim Link to comment Share on other sites More sharing options...
pskys2 Posted June 2, 2012 Share Posted June 2, 2012 (edited) From a 5" PC625 With Titegroup and 230 RN bullets I used: Montana Gold FMJ 4.3 and 1.225 oal 724f/s Ranier or Berry Plated 4.5 and 1.250 oal 745f/s Precision Coated/Lead 4.2 and 1.210 oal 730 f/s The problem with Titegroup is it gets real hot, real quick in sustained shooting and that leads to the possibility of scorching your hand on reloads. Yes it does get that hot. Clays seems the best and the most popular for Revolvers, around 4.0 seems to work with Jacketed/Plates loads. Remember the ejecta weight (which includes the powder charge) makes a minute difference in recoil. But the pressure curve can make a difference also. That's why you just have to shoot a load to see if you like it. Edited June 2, 2012 by pskys2 Link to comment Share on other sites More sharing options...
bobtorre Posted June 2, 2012 Author Share Posted June 2, 2012 Awesome info on the tite group issue above. I do have a 1 lb of Univesal Clays... So 4.0 grains is the ticket on a 230 grain jacketed round ball bullet...? Link to comment Share on other sites More sharing options...
Bosshoss Posted June 2, 2012 Share Posted June 2, 2012 Awesome info on the tite group issue above. I do have a 1 lb of Univesal Clays... So 4.0 grains is the ticket on a 230 grain jacketed round ball bullet...? CAREFUL most everyone shoots CLAYS not universal clays. I don't know if the load data for universal clays is similar or not. Most everyone shoots 3.6 to 4 to make major out of 5" 625 with lead bullets, jacketed a little more. 4.0 would be a good starting point. Link to comment Share on other sites More sharing options...
pskys2 Posted June 3, 2012 Share Posted June 3, 2012 4.0 of Clays not Universal Clays. Universal Clays is a denser powder with a slower burning rate and would take more to reach anywhere close to Major PF. Link to comment Share on other sites More sharing options...
buckaroo45 Posted June 3, 2012 Share Posted June 3, 2012 My 4" 625-8 took 4.3 gr Clays under a 230 gr Berry's plated to make 172 PF at last years Florida State. All revos seem to be a little different. Ya gotta have a chrono to be certain. Link to comment Share on other sites More sharing options...
bobtorre Posted June 4, 2012 Author Share Posted June 4, 2012 Clays it is... 4.3 grains pushing the 230s Gracias Link to comment Share on other sites More sharing options...
joedodge Posted June 4, 2012 Share Posted June 4, 2012 You gotta get a chrono to find out what your gun likes. My 4 inch 625 at area6 6 a couple months ago went 182 pf accross the chrono with 4.2 of clays there all different. Link to comment Share on other sites More sharing options...
bobtorre Posted June 6, 2012 Author Share Posted June 6, 2012 (edited) That is a drastic difference... Same gun and model and different speed.... What would cause this? I will chrono. My plan is to start with 4.0 and work my way to 4.3. Edited June 6, 2012 by zorro Link to comment Share on other sites More sharing options...

My plan is to start with 4.0 and work my way to 4.3. Not really, change in temperature could explain the variance. One barrel is tighter than another. etc etc. Link to comment Share on other sites More sharing options...
festus1 Posted June 6, 2012 Share Posted June 6, 2012 In the Hodgdon Load Center (http://data.hodgdon.com/cartridge_load.asp) the max Clays load with both 230 lead and 230 jacketed is listed as 4.0. Link to comment Share on other sites More sharing options...
joedodge Posted June 6, 2012 Share Posted June 6, 2012 Yes it is ........... Link to comment Share on other sites More sharing options...
pskys2 Posted June 7, 2012 Share Posted June 7, 2012 4.0 of Clays is the starting point. You will need more, most likely. Heck you can get a few tenths difference in scales also. But if you only shoot club matches it's a safe load. If you're going to any larger Match, you need access to a chrono, they're not very expensive either. Then make sure you check your final load in several different temp/humidity settings. Link to comment Share on other sites More sharing options...
