Too damn cold for me......
Please realize I have a 1/11 barrel...and that you should work up yourself carefully
....Also remember these loads are based on the Nosler 130gr Flat base SP-a discontinued product.(I picked up about 1k of them when I found they were stopping production, and I buy any I run across) The load is almost identical for the 130 Nosler BT hunting. And yes these are compressed loads. I do plan to try both the sierra 130's as soon as I can find them.
I found my safe max to be 28.7 gr. At 29gr, I have light swipes. The groups hover around 1-1.5 moa with all charges from 25.0 to 27.5 (in .5 increments) but after a good 120 rounds of detailed bench testing, the sweet spot for accuracy for my barrels is 28.2 grains. My best 5-shot group was .584 at 100 yards with my 18" SPR- average is .65-.7. The 16" groups reliably at around .8-.9
The data aside, the real world results with both the now discontinued 130 Flat Base SP and current production 130 NBT Hunting is absolutely devastating on the local hogs.
