A few weeks ago I tested some exploratory loads using Berry's 124gr HBFPTP and Longshot. The loads were evaluated at 10yards with the following results. These are all 5 shot groupings:
5.1gr, .93" grouping
5.3gr, .63" grouping
With these good results (for me) I decided to load up some additional loads and evaluate them at 15 yards. Following are the results. All 5 shot groupings again:
5.3gr, 3.5" grouping
5.4gr, 1.55" grouping
5.5gr, 1.40" grouping
5.6gr, 2.27" grouping (.97" grouping with one flyer)
5.7gr, 1.86" grouping
The 5.3gr result at 15 yards wasn't expected since I saw such a good grouping at 10yards. All other groupings are acceptable to me at 15yards, even the 5.6gr grouping which included a flyer.
My problem is that I am not sure on which loads I should spend my time on trying to fine tune it. It just seems to me that every time I try to work up a load in 9mm using Longshot, all my results are very similar with no clear trend to indicate the direction I should go in.
My initial thought is to just load 5 each again from 5.5gr to 5.7gr and see if any trend starts to materialize. Another option is to just pick one of them like 5.5gr and see if I can fine tune it a bit. Or I can just pick one of them, load up 25 or so, and go shoot them.
Please let me know if you have any ideas how I should approach the rest of my load workup with this combination of bullet and powder. Any comments will be appreciated.
