IMR4451 for 6.5 CM, .30 06 and .308

[General RE LEE]

I was able to get 2 lbs of 4451 and have 3 calibers to load for...6.5CM, .30 06 and .308. Is 4451 a good medium burn powder? Anyone load with it?

4451 was made to compete with h4350 back during the last shortage. I've tested it in several cases. I didn't get good accuracy until I got close to max load. Same applied to es/sd numbers. They got good near max. I also couldn't get the velocities with it like h4350. The decoppering agent works well. I had no visible copper in my bores when using it and I was shooting Barnes bullets.
