Old IMR data

[fuerza o razon]

Does anyone know where I can find an older IMR chart of loading data for 30-06 180 gr with imr 4320?

I used to find one online, but now on their website it just links to hogdongs website??

The Hodgdon website has data on the load you're working on, it gives data for IMR powders too.

Why not just use the updated data from the Hodgdon site or from a newer manual?

An old speer #8 manual gives a starting load of 47 grs./2563 fps, and a max load of 51 grs./2737 fps.

OP, if I may suggest. Instead of relying on internet sites, keep a log book to record the shooting history of your rifle with the loads you use and how well they work.

Depending on your requirements, your rifle will significantly change point of impact with every lot change of components.

I suspect that you are one of those folks that loads up a box or two every couple of years or more for hunting purposes only. I'm not knocking this practice if it works for you. I have a couple of rifles that get used in a similar manner. The thing is I do keep log books for the firearms I use. One other thing some people do is to copy the information concerning the load on the side of the box of cartridges. Masking tape with the information written with a black felt pen works very well for this.

I see what you are saying, but I do and have recorded the information for my rifle. I am trying to use a bullet I have not used before and instead of changing multiple variables. I am going to do just one at a time. The resource I used last was from an IMR data chart.

Thanks for the hints!

I like the sounds of that load... any chance you could post/email the reference?

The info I got for a previous load(that i recorded) came from a different chart then what they show now. My rifle reaally like it. so I want to cross reference it to the new one to see how much if any difference for a 180 gr bullet
