Thread: Burn rate / velocity / pressure / accuracy

Hey guys. School me on this please.

I get the relationship between pressure and velocity, and between velocity nodes and accuracy. I'm not sure how burn rates factor in to this.

Here's my question. I'm out of the powder I've been using for my 7WSM (W760), can't find anything equivalent but have plenty of AR2213sc. The burn rate is obviously different, but from what I have read it should be okay in the WSM. If I switched, would I have to start load development from scratch and find a new node, or could I estimate a charge that would give me a similar velocity and fine-tune from there?

Cheers, Rob
