I read as much as I can about reloading. Have enjoyed the activity thus far and have been able to shoot my own hand-loads at the range. Very satisfying!!!
My question revolves around the concept of finding YOUR guns sweet spot. Is it really that you guys just shoot a bunch and find one groups better? or do you have some sort of system or use a Ransom Rest?
I picked up some 124g projectiles and HP38 to start working up a load. Followed Lee's recommendations of 3.9-4.4 (min-max). Loaded 10 of each at 3.9, 4.1 and 4.3 grains of powder with an OAL that cycles well in my MP9. Shot them, didn't blow my hand off.
My method was that I shot from a supported position (hands on the table, seated) at my local range. All loads had a similar 10 shot group (slow fire) to factory ammunition. Was shooting at 15 yards. All would fit on a 4x6 photo. I did not see an appreciable difference between the loads besides my preference to how the felt.
Is there really some magical formula that I will see groups significantly tighten up? Or do you find that the variability of shooting 2 hands unsupported as most of us do in defensive type shooting introduces more than a 'good' load will actually compensate for?
I guess I am curious your method of determining your magical load. All of my bullets plunked, went bang, didn't have pressure indications and hit the paper pretty well. With my subjective preference being for the load of 4.1grains of HP38 behind the 124g FMJ
I was planning on doing a larger run of 25-50 of each, but thought I would pick the collective brain to see how others go about this.
