View Full Version : Jacket Seperation with Extreme Bullets brand

10-30-2010, 7:13 PM
First time trying bullets from Extreme Bullets LLC of Carson City, Nevada. Tried some 210 gr .41 cal copper plated bullets from Extreme Bullets. They look great and load well. I put together a .41 mag load pushing them out at 1600 fps. The load is accurate but suffers from jacket separation. No, it's not a timing issue as I've tried the same load in three different guns with the same results. A Blackhawk, a Redhawk and a Model 57 S&W.:( Perhaps the load is too hot and backing off the velocity would make the difference. Not sure, but like I stated, this is the first experience with this brand of bullet. Anyone else have this type of issue with Extreme Bullets?

I've heard plated bullets should be loaded similarly to mild to hot lead loads, max.

From what I gathered about the lead and plated lead, you can't load them at jacketed rates so you can't get those high FPS or you get separation and leading of the barrel. Info gathered says around 1000 fps.

I like the Extreme's; I've gone through 3 1/2 boxes and seem accurate in both RN and SWC for the indoor range.

I have over crimped plated bullets and had the same thing happen with 10mm. When you crimp you should have just a fine line on the plated bullet. Try seating and crimping on seperate stations.

I believe extreme say's to keep them below 1200 fps with the plated pistol bullets

Ranier and Berry's say the same thing
Berry's was trying out some double plated for magnum velocities but ran into weight issues.

All about bullet construction.

For ****s and giggles I tried loading 200 grain Speer jacketed HP's in my 454, they just flew apart. Not intended to be driven that fast.

I use unique for mid range loads for 44 mag and 10.0 grains gives about 1100 fps with a 240gr bullet, but the Extreme branded plated bullets cast of their plating at that charge.

8-9 grains, no problem at all. I still want a medium power load using 10g Unique, but I'm going to build them with jacketed projectiles I have stashed away.
