Anybody have any live experience with this powder for light loads in the .243?
Thanks, Tim
You do need to be careful, pressure mounts very quickly. The loads were accurate.
Thanks, Tim
Now you see why I won't do it from memory!
I would very much appreciate if you would post the info you have.

All of my varmint rifles have Hornet loads but loaded with 40 gr bullets in .22 cal for instance. I carry them for offhand shots to keep the noise down.
The imr sight with free data is at www.imrpowder.com.
These loads are light in report, very accurate and in most cases hit right on at 100 yards when the full house load is sighted 1.25" high. I use magnum primers with imr4759.
This is one of the forgotten ideas from the first half of the century and really a lot of fun.

Thanks for the input. It sounds like 24gr would be a max load, so maybe 15 or so is a good place to start, after all?? Perhaps 1894's data will confirm this.

Go to the imr site and confirm the data. Never take a internet load at face value. Always check a load in another book.
You can also calculate your own loads for most imr powders from the "Powley Computer", "Load Base" or other internal ballistic calculators.
I just looked at the imrpowders.com site and the max load for the .243W and the 80 gr bullet is 25.5 gr of imr 4759 at 2710 fps.
It has been my limited experience that 243 is quite pressure sensitive. I have experienced quite big differences in pressure signs according to the number of rounds fired. It's certainly not a round I would ever be tempted to go 'hot' on and allthough there is published data using faster powders I think great care is needed. My VVN140 data was pulled in a later edition, I think I can see why.
