Hey folks , I have some campro plated 230g 45 LC projectiles. Campro says to use jacketed data for these projectiles. I have trail boss and tightgroup powder. Hodgdon gives data for LRNFP only for this weight, with the two powders that I have. Question is , can I use the hodgdon data for my Campro projectiles? Is there that much of a difference between the lead and the plated projectiles?View attachment 36995View attachment 36996 I know that some plated projectiles ( berry) can use the same Data .

At those velocities you could use lead. Berrys bullets says their bullets can be run to 1200 fps, and their thick plated bullets to 1500 fps
 
I believe the gun ( Uberti 45 LC SAA) is rated for 13000 psi. So if I run a 230 g Campro plated and 6 g of tightgroup or trailboss , will o be close to 13000 psi
 
Given that this is a cowboy action gun I'd just work with the starting loads for Titegroup and perhaps use 6gns of the TB and call it all good.

The copper on the Campros will likely mean that you get a little less muzzle velocity. Something about the copper to steel and tighter fit of the copper not being as malleable so the drag is higher and we don't see as fast a muzzle velocity for the same charge as with a cast lead bullet. If you look at numbers for a round like .38Spl where there is a lot of comparable powders and charge weights for both cast, plated and jacketed you can quickly get a feel for this.

I'll check out the 38 special to get an idea. So if there's less muzzle velocity, does that mean less PSI also? I'd be sticking with trail boss but I'm almost out and it's so hard to find. So that leaves me with tightgroup or CFE pistol, but that's another story :) And Thanks.. Brian

if you had the same cases, powder charge, primers, bullet weight and shape, same OAL etc etc then the copper plated or jacketed would have a higher psi vs lead round. nothing to worry about at starting loads though,
 
Yep, a little more pressure needed to fight the friction means less pressure to speed up the bullet. And in fact because the bullet doesn't want to get out of the way as easily this actually might mean that the pressure is higher even though the ML is a touch lower.
