I have been using the same load data as for a jacketed bullet (90% max load) for all my powder coated bullets, including 50BMG. The powder coat seems to replace the jacket really well. Very slick down the bore with no fouling and I have not seen any issues with bullets flying apart below 3200fps - a nice single round hole at all distances. My 22 cal powder coated bullets run great up to 3200fps. At 3400fps from a 22-250 I get a black cloud about 10 feet in front of the muzzle - the powder coating cannot hold the lead bullet together like a regular jacket does at those high spin rates. I don't use gas checks on anything except 50BMG anymore with powder coated bullets and that is just habit for that. I use a 95% gloss powder coat from powderbuythepound.com (super durable series). Completely protects the bullet from hot gasses and completely protects the bore from the lead. Once the powder coat is melted in the powder coating process it cannot melt any more so no issues with friction in the barrel. The high gloss powder coating is actually more "slick" (less friction) down the barrel than jacketed bullets and I typically get faster ~50fps velocity in pistols and ~100fps faster velocity in rifles than identical load with a jacketed bullet. I switched from low-gloss powder coatings for this reason and no longer use those. Just some observations. robsbullets.com

50Shooter, I sent you an email. Thanks for being willing to try these out for me!

I have some .510 powder coated, tempered hardcast lead 890gr RNFP-GC bullets that a couple people have had quite nice results with, cast from an NOE mold. I would very much like to have a several more people try them out and let me know what load works best for them. If you are interested in helping me out, please let me know and I'll send some to you. https://www.robsbullets.com/store/p35/.510_890gr_LFN-GC_hardcast_powder_coated_bullet_for_50BMG.html#/
