What is Olin's problem with slow burning powders? About the time I got a decent load with W-785, it got dropped. Then came WMR. That one's gone too, but at least I found out in time to get a decent supply. Now WXR, and I never even got a chance to try it.
I've used WMR in a .243, 257 Bob, 270, 280, .300 Win. mag. and I plan on trying it in a .338 Win. mag.
Note that the 30-06 is conspicuous by it's absence. The only data I have is for 200 and 220 gr. bullets and I haven't been able to get decent results with a 180 gr. bullet yet. Velocities run slow and in nearing what might be a max load, they go screwy all over the place.
In all the above cartridges except the 30-06, I've gotten not only good velocity but very decent groups, all with very little load work up.
So, again I have to ask, why does Olin drop every decent slow burning powder they come up with?
This inquiring mind needs to know.
