Powder Equivalencies

I grabbed some Norma Oryx 156gr bullets for my 6.5CM. Not a real sexy bullet, but I was curious how the projectile would perform in my rifle.

Norma’s online info only shows Norma powders. However, they have a nice chart at the beginning that is a burn rate chart.

Right below Norma 204 ( with relative velocity of 100.9 and relative pressure at 98.9) is Hodgdon 4350 (listed at 100.0 and 94.9).

In the reloading data for the 6.5CM 156gr is a minimum charge of 35.5 and max of 39 using the Norma 204.

Would it be a safe bet to start a load at about 37.0 or 37.5gr of H4350 with this bullet?

I am just trying to make sure I am interpreting everything correctly.
Thank you!

Officially it’s best to start all the way at the bottom, but if it were me I’d do exactly what you said.
