My problem, if it is one, is that 3.7 grains of HP38 was good for both .38 and .357 cases with a 158 lead bullet. But after reading and taking advice I switched to a lighter bullet namely 125 lead. I still want to reload with the same powder charge for both but the .357 round out of a Rossi rifle is giving me pause for thought. I want light cowboy loads, I want to load the same powder charge...........has anyone tested a similar bullet/powder combination that satisfies?
If I hear you correctly, your problem is that you're worrying. Stop doing that.
You should be GTG with that load. Many of us run less than that amount of powder with 105 bullets and have no problems.
