I think it would actually be from rifle to rifle irregardless of make and model. Rifles are very individual in how well they shoot and what loads they like. You can take two identicle rifles off the production line and one might like something better than the other, or just not shoot as well.

And muzzle loaders are crazy considering there is no uniform barrel diameter from one maker to another.

I know my buddies knight likes very different loads than my remington does.
