[QUOTE="ottobounds, post: 2948834, member: 125584"] Doing barrel conditioning and fire-forming brass. Hornady Precision Hunter 175grn. 24" Proof barrel with about 70 rounds through the tube. Just a little sharing of my experiences: Lot #3231126 - Averaging just over 2850 fps. Lot #3224041 - Averaging right at 2900 fps. My gun LOVES the #323 lot. Cold bore just under 3/4" MOA. The #322 lot sprays the shots. Best group was close to 2.5" Crazy difference. I'm getting closer to having enough brass to start some load workup and clearly the goal will be to match up with whatever is in those #323 loads. I'm still not sure what powder Hornady was running for the 2023 production and if any of you know that detail, I'm all ears. I asked Hornady what powder they would chose to run in their personal reloads they told me that they love the way RL26 works in that cartridge. I lucked into finding 4lbs of RL26 at a local ammo shop so I have that to try along with H1000 and StaBall. Anyway, just sayin... Time will tell! [/QUOTE]
