Re: Newbie primer question
Some anal guys will tell you to start a little low and work back up, I'm not that guy but maybe should be.
For safety, I'd load maybe 3 rounds, 1.5, 1 and .5 grains under current. Shoot them each and look for pressure, the 4th round would be my standard load and I'd just go from there. Unless you were already at the very max load, getting pressure signs when it's warm, etc then I wouldn't worry about it.
I'm not saying that for accuracys sake you won't need to adjust your charge a hair, maybe .1 or .2 grains one way or another, but as far as safety goes it's been my experience that primer change won't make a load go from safe to extremely dangerous.

I would say as long as your not already at max load and/or somehwere between you will be fine. But if you are at max you need to back off a least a couple of grains to check. Some primers run hotter than others causing a pressure spike.

+1... I agree.
