Yep, still shooting this bullet in all my 35 cal barrels - 357 mag Contender, 357 Max Handi, 356 Rimless Marlin 336, 358 win Rem 700, 35X30-30 rolling block. It works quite well in all of them. Sadly, BRP is no longer in business but Tom at Accurate Molds can cut something very similar. A fairly long nosed bullet at .351" with small "tumble lube" type grooves.
I have since started using 15# green bar computer paper for patching, and find it is exceptionally useful for patching bullets to use with smokeless powder. It adds .012" and can be sized somewhat after patching so gives a large useful range of sizes.
I hadn't seen the post by rdlange, so sorry for no reply. Patched as normal - two wraps, ends almost butting together with no overlap, lube is vaseline/beeswax mix applied with fingers. Really any wax type lube works - Johnsons, car wax, shoe polish, whatever. It just needs to not soak through the patch and glue it to the bullet.
There are lots of special loading tricks for PP bullets to make them work. If anybody cares you can PM me and I'll be glad to share. Now that jacketed bullet costs and availability is getting so "interesting", I suspect we will start seeing more interest in paper patching. Time will tell...
