Hello,
I just got the 45-270-SAA RCBS mold, and I can't wait to try it..
(I do have the Brian Pierce article by the way..)
Which of these loads should produce the best velocity with that bullet in a 4-3/4 barrel without too much pressure (Pietta SAA):
1. 8gr of Unique.
2. 16gr of 2400.
3. 17 to 19gr of IMR4227.
Any other suggestion?
Also, I measured the chamber throats at .4525. Would it be better to size at .452 or .454?
I wish .453 dies were available..
Thanks!
