Has anyone used N203 or N202 in the 308 Win with 150/165/180's?

I've used NON-CANISTERED N-203 and 150 gr. bullets in the .308 Win for 30 years...42-44 grs. In my guns it is marginally safe, but one more grain (45.0 grs) occasionally blows primers, even in my rifles, so this data tends to be
HOT for my lot of powder. Loads using N203 have been exceptionally accurate in my rifles, that's the only reason why I continue to use this cranky stuff.

As this is non-canistered powder, I STRONGLY recommend you start BELOW THE LOWER FIGURE if you choose to use N203 at all. All the normal caveats apply, such as "You are TOTALLY ON YOUR OWN if you choose to either develop loads from this data, or use this data exactly. You cannot assume it will be safe in your rifle, and you should never use even the lowest load unless you reduce it 10% to start AND know how to work up your own loads and estimate your own pressures."

As I have no knowledge of your batch(es) of N203, your other components, your rifles, your techniques or your tooling, I accept no responsibility whatsoever for YOUR actions. This info is for information only, not for your use. If you want load and charge guidlines, visit the NORMA site. They have loading data for their current, canistered, powders there.

It should be noted that Norma powders are somewhat infamous among the reloaders I know for varying in burnng speed from lot to lot.

I use 45gr's of N-202 with a 150gr in a military case.
