I have just turned the scales on to warm up and was having a look at the load data for IMR 8208 XBR with 40 grain V Max and the figures from the Hornady book are considerably different to the IMR website.
The maximum load in the Hornady book is 36.5 grain and on the IMR website is 39 grain. This seems like quite a big differance for a maximum load.
Does these seem OK ?
Whilst working up should I stop at the books recommended maximum load or IMR's website.
