Loading data
 
First I am new to reloading. I have read the "ABCs of Reloading" and "Modern Reloading" by Richard Lee that came with my Lee Classic Turret press. I have also been doing a lot of research on the internet. I want to ask experienced loaders a question on bullet types and load data. I hope this is not a "stupid" question but being I could hurt myself and others I want to ask before doing anything.

I want to load 38 specials for my Ruger SP101. I have IMR 7625 and IMR700x powder. Bullet is a fully jacketed flat nose 158gr. Neither the Lee manual or the IMR site loading data lists this type of 158gr bullet. They have other 158gr bullets listed and give the IMR 7625 and 700X starting load for those but not the bullets I have. For the other 158hr bullets listed IMR 7625 starting load ranges from 3.7 to 4.0, for the 700X it is 3.0 to 3.2gr. What do you do in a situation like this?

Second question is similar in that I cant find the load data. I have 142gr 38/357 bullets and I cant find 142gr bullets listed anywhere for a 38/357. Again I checked the dia. and it is .357 and the weight is 141.6. I can find 140gr and 145gr but not 142gr. I was thinking about just doing the math and coming up with the starting load based on the differences between the 140 and 145gr but didn't want to do that unless I know that is the correct way to go.

Any help or just being pointed to a book or site where I can find what I need would be appreciated.

Thanks,
Ken

Fully jacketed or Plated? For jacketed just use data for a 158 gr SP or HP and you will be fine. For plated (or TMJ) use cast data.

When you cannot find data for a specific bullet weight, use the data for the next heavier, once again you will be fine

It would also be helpful if we know what brand of bullets you have. Not that brand name is critical, it just may help with your questions.

You can safely use the load data for a heavier bullet on your 142gr bullets. Does the bullet manufacturer have a web site with loading data?

No Sense to "Beat around the Bush"!
 
The NUMBER ONE offender of new reloaders getting into trouble with their loads is the POWDER!!

The two powders you have/have listed are NOT common .38Spl. powders.
Each powder company has the full listing of their powders, and the IDEAL loads that they are used in.
Spend $20-25.00 and buy yourself a pound of powder made for .38 Special.

If you can find it, WW-231/HP-38 is an IDEAL all around powder for most all pistol loads.

Not a rant, but USE the correct powder, and make SAFE reloads...Bill.:o

Unique is also a great all around pistol powder for ltght to medium loads.

dont experiment with shotgun powders in pistol cases. Buy the correct powder or you wont be reloading too long. Hard to do with some missing fingers.

I appreciate the feedback everyone. As you all know supplies are limited and I did not just buy powder without researching. I take reloading and shooting in general very seriously. I have no desire to hurt myself or others which is why I asked the questions I did.
If you go to the IMR site it states that both 700x and 7625 are great for handguns and even states specifically the 38 special under the 700x. If I can't believe the manufactures site where am I suppose to get the correct info?
If you google different powders you will get a wide variety of responses and opinions on which is best for different calibers. Moving forward I will look for the powders mentioned in the responses and I really do appreciate the feedback. I know I have a lot to learn and value your experience.

Thanks again. Ken

Doc most shotgun powders are used in handgun loading. I notice most of the powders you listed are shot gun propellants. As a matter of fact my skeet gun likes the 700 X. You may want to read some Burning Rate Charts.:)

I read it as a 158gn bullet.
Jacketed data would be 3.3-4.0gn 700X
Lead (plated data) would be 2.7-3.7gn 700X
If you can't find data for 158gn bullets, you're not looking hard enough.
