| I have an older Lee Data Sheet for relaoding 223 Remington. I had bought a Lee Die Set back in the mid 80's. It only had information for bullet weights up to 60 grains. The size dipper I have is 1.9 cc and the poweder my table uses for 55-60 grains bullets is Hodgdon H380. Any forum member using a new Lee Data Sheet that has a powder recommendation, using these size dipper, for a heavier bullet, in the 60-70 grain weight? I have found the advice on this forum to be very helpful. Twist on my rifle is 1/7 and unfortunately, none of my local store that sells ammunition has any rounds heavier than 55 grains. |

Using the 69gr Sierra Match King, I got this. 1.9cc = 26.2gr of H-322 - Too High 1.9cc = 27.5gr of H-380 - Near Max 1.9cc = 26.1gr of H-4895 - Too High 1.9cc = 26.9gr of RL-15 - Too High 1.9cc = 26.0gr of Varget - Near Max 1.9cc = 25.4gr of AA-2495 - Too High 1.9cc = 27.8gr of AA-2520 - Too High 1.9cc = 28.3gr of TAC - Too High Looks like you will need to use another dipper, or a scale. |

Varget is a good powder, though I do not use it. Using the 1.9cc dipper with the 63gr Sierra SP is a near max load. I would not want to start out with this load. Also keep in mind that due to differences in humidity, the stated weight to volume ratio can be off. Never start out with a near max load without access to a scale. |

PLEASE buy a scale and a couple reloading manuals!!!! THIS... I've found the Lee Dippers to be off by up to 10% on weight with different lots of the same type of powder. Also, his calculations were based off of formulations 20 or 30 years ago, therefore if the powder your working with has had any changes, you're going to be way off. I discovered that when loading with the "new" Unique. I had been using the "old" Unique, and the volume/weight calculations were pretty accurate, when they brought out the "new, cleaner burning" Unique it was off by like 20 to 25%. Now, the "new" and "old" Unique formulas burn the same way by weight, but the density is different. Moral of the story, get a scale and double check your loads. |

I suggest you get a set of Lee dippers. Included is a cardboard slide rule like guide for the various powders and dippers.
Also Modern Reloading (Lee loading manual #2) has a lot of loads listed and the dipper used for that load. A powder scale would be a good investment also. Good luck. |

For your 69-75gr bullets try H322 and/or H335
I like H322 for 75gr loads. Get a scale and some books is good advice. Accurate and Hodgdon have online data. Lee has their cc -> gr conversion chart online here: http://www.leeprecision.com/cgi-data/instruct/Dippers.pdf The 1.9 is wayy too much powder. |

Thanks , Guess I get the book from Midway USA. What type of scale would be appropiate for someone who loads about 20-40 rounds at a time, digital or analog? I'm leaning towards digital since my eyesight is making it hard to read small letters. I prefer ballance beam scales, don't let anyone tell you they are slow when measuring powder. If you do go with a digital, don't get a cheap one. (under $100) I have had several of the $30 ones, and they fail for measuring powder. They drift and I don't trust them. |
| Thanks for all the suggestions. I took the advice and pick up Modern Reloading, 2d Edition by Robert Lee. It is currently on sale at Midway USA through the end of the month. Lo and behold on page 226, it shows I can use H380 with a 63 grain bullet with the 1.9 cc dipper I currently have. Also the information he provides is eye opening too. |

It's a good book, some don't like it... But like all manuals...I do cross reference them to the powder manufactures websites....and any variation, I write side notes in the book and date the citations. The USA load books are nice because they are cheap/caliber specific and contain data from various bullet/powder manufactures...and give a place to add/modify recipes...(if updated information is different - NOTE: *use the data that was published for the year of your powder!) Start at the min values, usually they are accurate and will give your firearm the longest life span. |
