Well....., I wouldn't!

Start low- work up! This ain't a drag race.
No, the 39gr. that I mentioned was the STARTING weight recommended for 150gr. bullets, not the max. I figured with a lighter bullet, going one gr. over the minimum for 150gr. bullets would be OK.

And Mr. Horton - thank you very much!

And help me out here....how do most of you "start low and work your way up"? It's an hour drive to my range, one-way, so testing is a pain. Do you guys make like 5 rounds at a minimum load, increase the load and make 5 more, increase and make 5 more, etc., then keep them all separate and see how each load performs?

I don't have a chrono, or know anybody with one. And how in the world does an average Joe measure chamber pressures?
