Issues of leading the barrel with lead bullets and changes in peak chamber pressure when using jacketed vs. unjacketed bullets all come quickly to mind.
Handgun loading lead loads vs jacket loads?
I have a .380 mold coming from Lee in 100 gr bullets.My question is why do jacket
bullets in the same weight have different powder loads then lead.
I have a lb of Alliant Unique powder & can't find a chart for .380 100gr cast
but I can for 100gr jacket.
My Lyman 49th book is all jacket bullets in that cal & I can't find anything on
the net.Can I load my 100gr cast bullet the same powder loat as my jacket?

At those pressures and speeds Yes. Just size to fit your barrel, as most 9mm dia. barrels can vary and a .355 bullet will seldom yeild decent accuracy.

Well I loaded them 3.8 gr of Unique & they casted out to .556 & out shot any factory load I have
ever shot with that gun.No leading & I just tumbled in Alox.
Thanks Fly

Thanks Fly
I hope they wern't ".556" until they hit something solid.:laugh:I'm sure you meant .356"Well I loaded them 3.8 gr of Unique & they casted out to .556 & out shot any factory load I have

I recently bought the Lee Book&Press deal. My newest manual is probably from the early 90's and the press is perfect for bullet sizing. I looked in it for a cast load for a 158gr. 357 and the starting load was 5.9gr. Bullseye. I have a load on file with a 125gr cast at 5.0gr. Bullseye. It didn't seem right more powder and heavier bullet but I loaded some anyway at 6.0gr. They shot good and did not lead my barrel but were a lot hotter than I expected. I later checked my old Speer manual and found their start load was 4.3gr. Bullseye with a lead bullet and the max was 4.8gr. Granted the bullet was most likely a swaged design and was soft and that is why the max is low. Why didn't Lee make it's starting load 4. something? This is just another case in point of why it's good to have a few data sources to access and not try to rely on just one. BTW the mold was a Lee 158gr. .358" and although it is not a tumble lube bullet it worked fine lubed with the Alox liquid lube.
Wow. That's pretty quick loading and shooting. And I hope they were .356 also.Well I loaded them 3.8 gr of Unique & they casted out to .556 & out shot any factory load I have
ever shot with that gun.No leading & I just tumbled in Alox.
Thanks Fly
Wow .556,Hummmmmmmmmmmmmmm & I did not have even a beer.Thanks for pointing that out arat.
I noticed that Motor.The Lee chart for my .380 was a much hotter load than any of the rest.
Fly, check this link. When the page opens, scrool down to the 90gr. lead RN:Well I loaded them 3.8 gr of Unique & they casted out to .556 & out shot any factory load I have

Now next read and understand this:

Then check this:

My Lyman Cast Bullet Handbook also list a max load of 3.7grs. of Unique for the 92gr. cast bullet.
Of course alloy, bullet design and seating depth comes into play. Did these loads seem hot to you?
Armyrat, thanks for the links. stevespages looks like it contains a lot of info.
Did the loads seem hot?No not really.Now remember the Lee mold is kicking out 100 grain bullet & calling
for a min load of4.2 & 4.3max of unique.Then on the same page 95 gr bullet with 4.2 min & max of unique.
Another chart I saw some where called for 2.9 max of unique.Go figure??????
