Reloading 300AAC Blackout for accuracy
Since I purchased a Ruger Ranch in 300AAC to complement my DDM4 in the same caliber, I have been attempting to find a high accuracy load.

Currently the best result seem to be with very lightweight bullets (110gr Hornady V-MAX with flat butt). I've tried pretty much everything in between. I have tried getting very close to the lands. I have tried N120, N110, N105. I have sorted the brass by weight, sorted the brass by length. Trimmed the brass from the shoulder. All sorts of attempts.

Nothing really give me the accuracy I desire (or not realiably, which is even more frustrating).

I have been using GRT (Gordon's Reloading Tool) with great success regarding velocity, but it wasn't of much help regarding accuracy and in finding nodes.

I had to stop my attempts due to the birth of my baby, hopefully I will get back on this subject at some point.
Since then I have received an annealing machine from an Australian company, and some fresh brass from Starline. Until now I reloaded exclusively S&B without annealing.
