Re: .270 wsm powder
I would start at 63.0 grains and go up in .5 increments. Somewhere around 63.5-64.0 sure works nice.
No one in Utah has any RL17 to my knowledge. I think I have the only pound that exists in Utah for now. I checked all my sources and I have many beyond the big chain stores and had no luck.
If it's not far, it's boring.
