I sometimes include Norma powders in my handloading articles. Just did one on the 6.5x55 for my column in GUNS, which will be out in a couple of months, which includes several Norma powders, as well as some Vihtavuori powders.
Thank you I'll keep an eye out for it. Reasonablish assumptions as to burn rates:
Norma 202 approximates IMR 4064 (on Hodgdon chart)
Norma 203B is somewhere in the N150 range?
Norma URP is near 204, which is RL19ish range?
Norma claims URP is a little less temp sensitive. Any truth there?
