RE: Different cases/different weights-will they affect performance in hunting loads?
 

Yes, it will make a difference. For Federal brass, I have to drop my load some. But with remington, I have to raise. Not only is wieght the difference, but the hardness of the brass.

WEIGHT ALONE CANNOT TELL YOU HOW THEY WILL PERFORM. THE HEAVIER MAY NOT HAVE AS MUCH CAPACITY, MAKING YOUR MAX REACHING DANGEROUS LIMITS. AT BEST, REDUCE THOSE LOADS 5% AND TAKE A FEW TO THE RANGE. TO GET AN IDEA, FILL ONE OF EACH CASE TO THE TOP, WEIGH THE POWDER AND SEE IF THERE IS A DIFFERENCE. PLAY IT SAFE!

This may or may not apply, but when switching from lighter commercial cases to heavier military cases in .308 or .30-06.......the NRA reduction formula calls for taking 12% of the case weight difference and reducing the powder charge by that amount.
So in your cases, the PMCs should be reduced by .6gr of powder. This may be overkill, but it does give a safe, reliable starting point to figure out what you need to do.

RE: Different cases/different weights-will they affect performance in hunting loads?
 

It' s a good idea (safe) to always reduce the powder charge when changing ANY component in a maximum load such as primer,bullet,case;)

Always seperate cases by head stamp. Good luck.

RE: Different cases/different weights-will they affect performance in hunting loads?
 

It COULD make a difference, but not necessarily. It depends on whether or not there is a difference in case capacity, and checking to see how much difference there is, if any, is the best idea. I use a small grain-size ball powder, fill to the case mouth, then tap the case to settle the powder. Then I dump it and weigh it. Same with the other case. I generally use H335 for this capacity comparison testing.

748 or H380, would also be good to do the comparison with. I also find that the two are pretty close performance wise with what I load for. That' s not saying you' ll have the same results.
