I am usin WW 130 -/+ bullets that I cast and Tite Group powder, my book tells me that the min powder to use is 3.5 and the max is 3.9. I just rechecked my powder dispenser and it showed that I have been shootin 3.3 grains of powder. I have bout 900 rounds left with that load. I have good POI with that load, it's a swinging target and I am firing fast. And I'm gettin good penetration (long ways). Is there something I should worry about with that small of a load? It seems to work good for me, why should I change??
As long as your load is doing what you want it to do don't worry too much about it. Minimum loads listed are there so you don't get a load so light that it fails to exit the barrel leaving you with an obstruction when the next round is fired. Since your loads are cast they will have less barrel resistance than a FMJ round. If you ever fire a round and don't get some indication of bullet impact you might want to check your barrel though.
