Hi, I’m brand new to reloading and could use some help.
I purchased some V-max 87 gr. 243. and IMR4350 powder. When researching what load to use I am finding some conflicting data. Hoping you guys can help me out with a few questions.
1. The Lee manual and the Hornady manual list Accur4350 not IMR4350, and it shows their burning rate 51 & 50. Are the powders the same? Or should the loads be different.

2. Another conflict I have found is the min & max loads. Lee’s data for 87 gr Jacketed is min 41.8 gr & max 46.4. And Hornady’s data for 85-87 gr is min 39.9 & max 43.4. Both of those loads are in A4350 not IMR4350, which is the powder I have. I googled 87gr V-max & IMR 4350, most of the recommended loads I found are 43 or 43.5 gr of IMR4350. Which is the Max load according to Hornady.
What do you recommend the min & max loads from your experience?

3. Also do any of you have experience with 87 gr V-max and IMR 4350? What load worked for you?

Thanks much for your help.

What are you loading for(like what kind of gun)? Good advice is always to start near the bottom (I always start about 10-15% above the min) and go up. Look for pressure signs and have fun. the Load charts are not set in stone they are more guidelines. As far as A4350 vs IMR4350 I dont think they are the same but I've never used either so i dont know.

IMR on their website say for a 90 gr min max with that powder is 42.0 to 44.9C, So I'd start right about the 42 mark (maybe even 41.5)

Remember you're putting a controlled explosion right next to your face, always better to be on the side of caution instead of starting with a hot load :)
 
1. Powder with different names are different. You can NOT use info for the other. There is the odd exception but you are not at the stage to worry about that yet. 4350s are all different.
2. You need to work up a load from the min to find your load. Every rifle is different. I think you need to read your manual again on how the process works.
3. I don't use that exact combo.
 
Go to the Hodgdon website and check out the reloading data for IMR 4350. Start with, and stay with, the minimum load until you get a few rounds under your belt.
 
Most of us were newbies one time and we did not have the web to help or confuse us. As said go with Hodgdon web start with min check your case for pressure signs. I have a few hand loading books and just about every book is a bit different using same powders when it comes to min/max.
 
As stated above - don't interchange the data from one powder to another and always start with the minimum load. Use these links for Nosler and Hodgdon sites for data. The Hodgdon site only gives you three choices for powder: IMR, Hodgdon and Winchester, which is fine for you now as you have IMR to work with. The Nosler site give data using a handful of different powders but you can not select from a list.

Having the books is great, there is a bunch of other information in, them but the on line data sources are kept up to date without having to purchase another book (new powder or bullet availability).
