WOODFOX , sass#34179 Posted March 26, 2016 Share Posted March 26, 2016 I'm starting using 700X in my 45's I'm loading at the minimum load with a 200gr. rnfp and it is leading up in my pistols . I have been using win 231 with no leading but the stuff is so dirty thats why I changed . If anybody has a good load for 700X please PM me . I always thought leading was caused by too much powder does it work both ways ? Woodfox Link to comment Share on other sites More sharing options...
Tex Jones, SASS 2263 Posted March 26, 2016 Share Posted March 26, 2016 Yes. Not enough pressure being generated with minimum load so that the case does not expand enough to seal the gases. Upping the load should reduce the leading. Link to comment Share on other sites More sharing options...

Chuck Would, SASS # 53289 Posted March 26, 2016 Share Posted March 26, 2016 I use 231 or HP-38 with a 250 grain bullet. Yes, the load is pretty light and the case does not completely expand (Forgive me Driftwood, I've forgotten the correct word for that.) to keep the cases from getting sooty from the blow by but I've never had any issues with leading. I wipe my firearms down after each shoot and put them away. Once a year or so, I do a full tear down and clean them. Never had any issues. Link to comment Share on other sites More sharing options...

SHOOTIN FOX Posted March 26, 2016 Share Posted March 26, 2016 Look to the IMR load data for loads thatvwork. Middle of the road works best. Which lube are you using on the bullet? Fox Link to comment Share on other sites More sharing options...
Garrison Joe, SASS #60708 Posted March 26, 2016 Share Posted March 26, 2016 Low velocity or low chamber pressure by themselves will NOT cause leading. You've changed something else - lead alloy, lube, bullet diameter, I'll bet. Just a change powder with the same kind of chamber pressure is not going to cause leading. I shoot a lot of .45 Colt 200 grain over light loads of 700-X. That load is actually just below the bottom of what is the low end of the scale from Lyman's latest Cast Bullet Handbook. I use a fairly soft lead alloy - about 8 Brinnell hardness. Not a speck of leading. I'll PM you my load, but I'll say it again, it's not due to changing to 700-X powder, and it's not due to low velocity and pressures. Something else is the root cause of leading. I'd bet you are using some fairly hard lead slugs and perhaps slightly smaller than your groove diameter. Gas cutting at the slug's base is much more common cause of leading with our cowboy loads, because of using HARD lead alloys. If you are using commercial cast bullets, you are shooting a pretty hard alloy most of the time. And, gas-cutting leading is common right at the barrel throat, in the forcing cone and the next half inch up the barrel. Take a close look and see what part of the barrel that leading is occurring in. Good luck, GJ Link to comment Share on other sites More sharing options...

The opposite is true, an 8 to 12 brinnel alloy makes a much better, cleaner shooting and accurate bullet. The casters use a 18 or higher brinnel alloy because it works better in their high output casting machines. Period, that's the only reason for the hard, bordering on brittle, alloy they use.

Will Lynchem Posted March 27, 2016 Share Posted March 27, 2016 Woodfox, I have used 700-X (when I can't find Trail Boss) in my 45 loads quite often. 700-X also burns on the dirty side but I have found that if I stick to about the middle of the load range recommended by IMR on there web site, I have very good results and manageable recoil. I never have had a "leading" problem but then again I use a moly coated 200 gn RNFP. It works great in both my lever action and my 1911 for wild bunch. Good luck, W. L.

Ripsaw Posted March 27, 2016 Share Posted March 27, 2016 Missouri Bullet Co. cowboy bullets (brinel 12) with the hi tek coating (or without) do not lead my barrels with light 700x loads in .45 colt. Or Clays, or red dot, or...whatever., The key is proper bullet size and a soft alloy. Link to comment Share on other sites More sharing options...
watab kid Posted March 27, 2016 Share Posted March 27, 2016 its burn rate is comparable to red dot / clays / i use all three Link to comment Share on other sites More sharing options...
WOODFOX , sass#34179 Posted March 27, 2016 Author Share Posted March 27, 2016 I have been shooting the same bullet for over ten years I don't know the hardness but as I said no leading with 231 so i guess it's the low powder charge I'll increase it and see what happens thanks to all that helped .

Cowboy Junky Posted March 28, 2016 Share Posted March 28, 2016 its burn rate is comparable to red dot / clays / i use all three When powder was hard to find so did I........also used all three in 38's and shotshells. Link to comment Share on other sites More sharing options...
