Re: IMR 8208XBR?
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: dan46n2</div><div class="ubbcode-body">I posted this in another thread but here it is. Also notice that the 8208 is in PSI which is actually lower than CUP. 53000 PSI is about 48000 CUP. So it looks like it could beat out the competing powders listed in velocity if pressures were matched.

Keep in mind the limitation is 58,000 psi for .223 rounds. 62,000 PSI for 5.56 NATO.
I don't understand why Hodgdon (IMR, Winchester) is listing 40k something psi loads for a 50+ psi round. That's pathetic
