You won't find N205 on that list. You can find data in old books. N205 was discontinued decades ago. Norma's explanation was that they were having issues controlling burn rate of N205 and replaced it with MRP.

I used N205 in my 270 with 150gr partitions and 30-06 with 180gr partitions (don't recall the data, it was a LONG time ago). I still have a couple pounds of it. N205 is very temp sensitive and is a slow burning powder. It is #164 on this list:

I have an old SPEER reloading manual number 8 from 1970 and it lists the loadings for several calibers for N205. They range from 25/06 thru 30/06 and maybe a few other calibers. If you have specific calibers I could send you what the manual has.

I was hoping to use it up on praire dogs ,but a 25 or 30 06 is a little to big .whats the smallest caliber i use it in?

It's much too slow burning for smaller calibers. 243 is the smallest caliber listed in any of my books from the 70's. This is from the 1973 Hornady Vol. II book:

The smallest that is listed in my 1970 Speer book is .244 Remington, 6mm Remington, 240 Weatherby Magnum, 6mm/284. 25/06 and up.

Better to post an intended use, bullet weight, and cartridge. I have some data. It's a slow burning powder like H4831.
