I looked into this a little and I think you are close, but you need to research it a bit further. For loading Rainier you need to look at data for lead bullets, not jacketed. I THINK you are close to a safe charge but since I don't have all the details I don't know if you are closer to the minimum, the maximum or maybe a little oustide of the scale.Ted D wrote:I don't know where to put this.I'm new to reloading I have all my equipment set up.I'm reloading 9mm.I'm using federal and blazer brass cases,115grain Rainer bullets,Federal small pistol match primers,and Unique powder.I went on the alliant website it didn't give me the recipe for this setup.It gave me sreer bullet,cci 500 primer charge weight of 6.3 grains.The guy at the gunshop said to start with 6 grains.My charges are coming out at 5.8 grains would that be a safe start?(on the lee die set the oal is 1.69 mine are 1.15)also the finished product has very small scratches on the case when I rub my fingers on it they are smooth is this ok?And also should I fractory crimp it?From all the things I have read some say not to others say to fractory crimp.YOUR HELP IS VERY APPRECIATED.
When asking a question on here, more specifics are needed. The brand and weight of the bullet is good info but what type is it? I am assuming you're just using thier regular plated RN but I don't know. Also, when you're quoting lengths and powder charges are these min, max? Only one listed in your scource?
Scratches... Is this new brass? Once fired?
Crimp..That's kind of hard to answer because I don't know what you got goin on there. Normally a slight taper crimp for 9mm is fine.
This is from the Rainier site.
We, at Rainier Ballistics, recommend using lead bullet load data when loading our bullets. There is no need for adjustment when using lead bullet load data. Our bullets are jacketed using an electroplating process and are softer than traditionally jacketed bullets; hence the recommendation to use lead bullet load data.
If you only have access to traditionally jacketed load data, we recommend a starting powder charge directly between the listed minimum and maximum load, and you may use published load data found in reputable reloading manuals.
A slight roll or taper crimp may be used with our bullets;
Overcrimping plated bullets may result in decreased accuracy, and fragmentation of copper plating.
