I've got a bunch of new Starline brass and a new G20 to shoot it in. For my Colt and Mec Tec I've been using 180g lead and W231.
The Glock I've read and been told doesn't do well with lead, polygonal rifling. So for the G I bought a bunch of 180g heavy plated bullets from RMR. They say to load like jacketed. ? 1, do I trust RMR and load as they say? Or load like lead? ? 2, Which powder to use? I have A LOT of bullseye, 3# each of 231, True Blue and Blue Dot. All of which my manuals cover. Layman # 48 & 49, Hornady, Speer and Nosler. ? 3, Layman says to trim the cases to the same length since this round head spaces on the mouth. Is new brass that different in length? I also have 1,400 Hornady 180g HP XTP I'll be loading some of those, which powder for these? Thanks y'all! ETA 180g |

From Berry's plated bullets.
Plated bullets occupy a position between cast bullets and jacketed bullets. They are soft lead, but have a hard outer shell on them. When loading plated bullets we have found best results using low- to mid-range jacketed data in the load manual. You must use data for a bullet that has the same weight and profile as the one you are loading. Do not exceed mid-range loads. Do not use magnum loads. Of the powders you have listed I would go with True-Blue. Blue Dot is s popular powder in the 10mm, but it works best when loaded to the upper end, low to mid range loads do not perform well. It also has a ton of muzzle flash. I also have 1,400 Hornady HP XTP I'll be loading some of those, which powder for these? What weight. |

What grain are you XTP's, my 20 really likes to eat up the 200gr and spit em out without a hitch. True blue but do refer to a reputable loading manual, if you don't already know better yet. The nice thing about the 10mm is that there are a lot of great loads out there. You can fire a .41 or a .40 caliber bullet, opening up the menu of bullets quite a bit and can load hot, as a companion on an archery hunt, or cold, for frangible ammo and so on.
I have four different loads I'm particularly fond of but, unfortunately, we are in the midst of moving and just about everything we own (save some clothes, the guns, and loaded ammunition... they never go far) is in storage as this transition hasn't been as smooth as I had planned. In other words, my notes are buried and would require a small search and rescue team to locate any time soon. Hot Mess Express, when I find my notes I'll be happy to share my favorites (if I remember, still trying to figure this forum out). |

Blue dot is a speedster in 10mm auto. Load with it if you want high velocity. I have made plinking loads for my S&W 1076 with bullseye, but I was using the start charge in the Lyman cast bullet manual and the rounds weren't hot or fast.
I've never used plated bullets so I can't recommend a plated bullet specific powder or load. |

My experience with handloading 10mm Auto is still kinda limited but I loaded a few 180 gr Berrys plated that I'd had leftover from my .40 S&W in new Starline 10mm brass with 7.8 gr Power Pistol and was rewarded with a nice, accurate load from my S&W 1006.
When I bumped that up to 8 gr of PP my groups looked more like patterns from a shotgun. 8 gr of PP under Hornady HAP 180's brought back my nice satisfying groups. Obviously I found the threshold above which my plated bullets in this particular load simply crapped out. Blue Dot seems to be a very popular powder for full power loads along with Power Pistol (which I used cause I have 8lbs), IMR800x, AA#9 and Longshot. Never used RMR bullets so I can't comment on them other than to say if they're saying to load like true jacketed bullets I would start at the low end of jacketed data and work my way up to where I wanted to be. You certainly should have no trouble finding a great load with your Hornady XTP's. I have never trimmed a piece of pistol brass and cannot imagine a reason why I ever would. IMO it's simply not necessary. |

I love Blue Dot for 10mm, but as mentioned above, the flash is considerable.
With 180 gr XTP's, 10.0-10.5 grains of BD is pretty mild with CCI LP's. Thats with Starline brass as well. Ive found that its pretty much the lower end threshold in my gun for performance, but I think that load is fairly high in my load manual. Below max, but only by half a grain or so. Out of my 6.6 inch LW barrel, it was around 1200 fps. Ive never shot any of those loads in the factory barrel, so I dont know if it will leave a smiley. I havent noticed any pressure signs in my spent brass. ETA Properly sized "hardcast" lead (usually anything around 15 or higher on the hardness scale) wont leave any lead at all in your Glock barrel. The key word is "properly sized." |

Do you consider Missouri Bullet properly sized? Maybe you haven't tried them. They are real popular over at THR, my 2nd favorite gun board.
Thanks guys for the info. I rarely, like almost never load at max charge. I just don't need to. I think I'll load some of each powder and see what happens. If I'm lucky BE will be really nice but it probably won't be, oh well. |

Is new brass that different in length? I also have 1,400 Hornady 180g HP XTP I'll be loading some of those, which powder for these? #1: I haven't loaded RMR 10mm bullets, but have used their .45 230grs. Good bullets: the plating is thick and uniform. The only thing I'd be curious of with the 10mm 180 gr bullet is the diameter. Is it .400 or .401? Anyway, as others said, use mid level jacketed data. I would back off one grain of powder from the max as the top limit. #2: Of those powders, I've only used Blue Dot for the 10mm. It is a very good powder for this round, but doesn't meter very well. I use Blue Dot behind 180gr lead as a plinking load. I don't go to hot, 9.0-9.5 grains of Blue Dot. #3: With new Starline brass you shouldn't need to trim the cases. Starline has some info on their FAQ page. For the Hornady 180 grs, Blue Dot will work, but so will AA #7 and Power Pistol. I would use something that metered better than Blue Dot for jacketed bullets, unless you are just making "plinking" loads, or wish to weigh each charge. |
