.36 caliber

I'm hearing many more people saying that 30 grains is what they use. This will give me a good start. I purchased it for squirrels anyway. I'll start there and then go down or up.
Thanks hanshi

The usual method is to start low and work up. That's because it's easier to start at one end and work to the other than start in the middle and work both ways. I'd start with 20gr, increase in 2 or 2 1/2gr increments till I find the "sweet spot."
Most important thing in my possibles bag is a little notebook and pencil. Has to be a pencil. Ink-pens leak. Ask me how I know this.

Thanks for your help D Of M. At what range should I start shooting, 15, 20, 25, 30 yards?

That's really up to you. I'd start off at maybe 20. Shorter range forgives shooter error to a greater degree. Once you have a good load, move the mark out to 50 or wherever. Don't be surprised if you have tight groups but they stack slightly differently at different ranges. I have noticed that and put it down to the faster twist than was traditional for RB, but I'm still dipping my toes into learning about how velocity, bearing surface of the projectile, resistance. and rate of twist interact with one another. Hence the notebook and pencil.
