When trying my “normal” OAL of 1.120 inches, I found the new hollow back flat point bullet was hitting the lands on one of my pistols (but not the other one). The hollow back causes the bullet to be longer, with the result being more bearing surface during passage through the barrel. I do want to mention a problem I encountered. Developed a really cracker jack target load with W-231 and ran out of bullets. Liked the results with Unique and Power Pistol so I bought 1000. Please find a mentor to help out.Bought 250 of the Berry’s 124 grain HBFP (hollow back flat point) for testing. If you don't understand it well, or are unable to extrapolate the data for yourself. Verify that this data is correct for yourself by checking at least 2 other pieces of printed load data. This is the Internet, but I'm a human and could have made a mistake, error, or even a typo. Do Not start right out at the maximum loads.ĭisclaimer: If you use this data, do so at your own risk! I would recommend following the more recent modern Lyman load data, and starting around 4.4 to 4.5 grains of Unique with a 125 plated bullet, and working your way up until you find reliability and accuracy, with 4.9 to 5.0 grains of Unique being your plated bullet max. At one point in time however these loads were considered safe to use Needless to say these are maximum loads - You were expected to reduce the max load by 10% to start, and work your loads up again to max or near maximum. Source - 1991 Hercules reloading pamphlet. It also serves nicely as a data comparison between Herco and Unique. This data was pretty hot, and I would NOT use it anymore, though I did back then. Unique 5.5 grains MAX = 1122 FPS (no pressure data)įor comparison purposes, here's some warm older 1991 Hercules load data from before Alliant had taken over Hercules and began listing BE-86 as the only powder choice for most calibers online.

Unique 4.5 grains Start = 1057 FPS and 24,900 C.U.P OAL = 1.010 - 4 inch barrel, universal receiver. Source Lyman Cast Bullet Handbook (2010) 4th edition: I'll look at a few different versions of load data, so as to get a better idea of what I'm doing before starting out. Pulling a loaded cartridge after crimping is an easy way to check to see if this is happening. Use a gentle/light taper crimp with plated bullets. Also be careful during the crimping process that you don't crimp too hard and cut through the plating. I don't try to push plated bullets to jacketed velocities for fear of stripping the thin copper plating from the projectile. Many of the cast loads listed previously in this thread would also work nicely with plated bullets. I've done so myself when using plated bullets. You can easily use a 125 grain 9mm cast Unique load, from the Lyman Cast #4 handbook and have it work just fine. You could try contacting the plated bullet manufacturer to see what they say about it, and also see if you are able to obtain any load data directly from them. Many plated bullet manufacturers recommend using cast lead bullet data with their plated bullets. Both powders behave almost the same, with Herco being a tad slower than Unique. ![]() Anyone have a recipe for Unique and 124 plated rnl? Looking for general purpose plinking loads I can run through several 9mm pistols.I've always been under the impression that slower lots of Unique, simply get labeled as Herco. Will be switching to Hercules Unique when the Herco runs out. Going to take them to the range this week & try them. I just loaded 50 rounds using 5.2 grains Herco behind a 124 copper plated rnl.
