hey guys hope everyone is having a good weekend, I picked up some tite group pistol powder and was
wondering if this sounds ok. since the load data is different on the bottle and on line. the load data for 9mm 115 grain plated round nose and the 40 s and w 180 grain plated flat nose is all over the place I already check the data that is on hodgdon web site, so this is what I did. for the 9 mm I used x-treme plated with 4.2 grains I did load some with 4.0 and the 40 cal I used 180 grain plated x-treme with 4.3 grains I also loaded some with 4.0 is this a good start point? Thanks guys 
I fixed the all caps in your title. Please do not do that again. dryflash3 |

Yes, treat plated bullets like they are cast lead waxed bullets, and work the loads up checking the primers for signs of over pressure. The date your looking for is under 115 and 140 RLN loades for the 9 and 40 for your start pressures, and the max you want to work them up to in regards to Gr drops of powder.
Also, standard small pistol primers, and not magnum small pistol primers!!!!! As for your over all lengths of the rounds, standard lengths listed in the data will work, but I tend to just load them .005" from the bullet engaging the rifling on lock up isntead. Hence this allows you to longer load the ammo, leaving more volume in the case to lower the working pressures isntead. |

My experiences with Tite Group and Xtreme:
9mm, 124gr Xtreme Heavy Plate Concave Base, 4.3grs Tite Group, CCI 500 Small Pistol Primer. Shoots accurate, cycles in all my 9mm pistols. Only restriction on plated bullets is keeping velocity below 1500fps as the plating may "peel" off. Absolutely nothing wrong with using Magnum primers in non-magnum cartridges. With the exception of Tite Group, I use CCI 550 Small Pistol Magnum primers in all my 9mm loads. Even when getting close to maximum powder charges, you'll still be only at +P pressures. Better powders for 9mm: HS-6 (my favorite), AA #5, CFE Pistol, Silhouette. I've been using Silhouette for +P loads, can't tell a difference in recoil from factory standard rounds. |

Yes, no, maybe.
Hence magnum primers have slightly thicker primer cups, so why will have the correct "Look" spent primer signs of the higher pressure loads. So you can use them with mid range powder standard loads and may not have problems with over pressure, but when you do start banging on the door of over pressure in a non magnum load, may not give you the correct spent primer flattening signs isntead. |
