I finally downloaded the data from IMR's website on .30-06 and found the load data for XBR 8208. It spans over several bullet weights.

However, in my Hornady book it does not list 8208 for my Garand. Can I just load 150's and 168's in 8208 to the same FPS listings that are listed for the Garand?

My intention is to make 8208 XBR my primary .30-06 powder.

In a word, no. The Garand needs a load with the right pressure curve or it may bend the operating rod. Just because you could load to the same velocity, doesn't mean it has a compatable pressure curve for the Garand. While it may be possible to load for the Garand with that powder, I myself wouldn't experiment as I don't have the equipment to measure the pressure curve of the load. A chronograph isn't goint to tell you anything about this curve.

What he said^. Stick with proven powders for gas guns.

Timco, have you seen, or do you have, the historical articles for Garand loading?

Many of these articles are floating on the web. I don't recall seeing 8208 on the lists. Let me clip an article in here if I have them on this hard drive.

Don't have them with me, but here is a link to some historical M1 loads.

and this is a little dated, but down the text you can see where the burn rates favored by the Garand will fall.

The Garand is still magnetic for me too, just can't help myself when one comes out onto the line.

Save that 8208 XBR for your heavy .223 rounds, that's where it really shines!
From what everyone tells me, IMR 4895 has the right pressure curve for the Garand.

H335 has been doing well for my Garand. The latest Hornady book has many powder listings for the Garand.

Going to try Accurite No 9 for my Carbine next. Been using H110.

Thanks for the input!
