Badger Mountain Charlie SASS #43172 Posted December 27, 2013 Share Posted December 27, 2013 I do not shoot .357 or 38 long guns. My Grandson does. I want to load some bullets for him using lead bullets. Probably 158 grain. What is the magic number for muzzle velocity to allow lead to be used and not cause leading in the barrel? Ken ya hep me?

Buckhorn Bud Posted December 27, 2013 Share Posted December 27, 2013 The rule of thumb is a maximum of 1200-1500 fps. But, having said that, a lot depends on the hardness of the bullet and the lube you use. Link to comment Share on other sites More sharing options...
Badger Mountain Charlie SASS #43172 Posted December 27, 2013 Author Share Posted December 27, 2013 Thanks Buckhorn. Reading a little further I found the information about the leading and MV. Still looking at the formula though. Thinking of using HP38 Hodgdon powder and a 157 grain bullet. Link to comment Share on other sites More sharing options...
Chickasaw Bill SASS #70001 Posted December 28, 2013 Share Posted December 28, 2013 BMC just looked up the max load of HP38 , listed pressure and speed (1109 fps ) does not look to be a problem with a hard cast CB Link to comment Share on other sites More sharing options...

Chickasaw Bill SASS #70001 Posted December 28, 2013 Share Posted December 28, 2013 BMC most commercial , will have a Brindnell hardness listed on thair website , if not on the box at the listed pressure and vol , from the LEE book a 10 + Brindnell sill be good to go Handcast from wheel weaights , should also be fine if you can mark the projectile with your thumbnail , like a round ball for B/P , you are probley going to get some leading IF there are Lazer Cast , them be real hard , 16 Bin , if I recall correctley , I have pushed them , WITHOUT a GC , over 1800 fps without problems CB Link to comment Share on other sites More sharing options...
Badger Mountain Charlie SASS #43172 Posted December 28, 2013 Author Share Posted December 28, 2013 Laser cast list their Brinnell at 22 on their web site. Another vendor list his at 16. I am looking at around 1100 ft/sec for MV. I suppose that either one would work without problems? Link to comment Share on other sites More sharing options...
Chickasaw Bill SASS #70001 Posted December 28, 2013 Share Posted December 28, 2013 BMC I do not think , you will have any ill effects , eather way , load em up and send em downrange , REPEAT as needed CB Link to comment Share on other sites More sharing options...
Tom Bullweed Posted December 29, 2013 Share Posted December 29, 2013 LaserCast, Oregon Trail and Miester sell hardcast bullets that can be loaded to 1500 fps without leading a microgroove barrel. They can provide the information about the Ballard-cut barrel used in a Marlin cowboy gun. Softer bullets, including Hornady swaged bullets, will lead a barrel at over 1200 fps. Shooting a heavier bullet of 175-180 grains will also generate lower velocities. Link to comment Share on other sites More sharing options...

BLACKFOOT SASS #11947 Posted December 29, 2013 Share Posted December 29, 2013 Bullets from most any reputable caster will do fine if the SASS maximum velocity is not exceeded. Lafitte Link to comment Share on other sites More sharing options...
