Anyone load these yet? Results??

I loaded some with h4831sc. Found a node at the high end. After testing, I still had a round to check pressure with and 2 others from the testing group left. I let those fly at the 500 yard targets and hits at 1moa targets. I'll retest around the node and take some paint with me as well later this week.

So far hornady's manual has been spot on for speed for me. No chorno for me so all my speeds are adjusted from drop data.

Not much data out there yet. You are plowing (almost) virgin ground. Be proud to be one of the first. Looks like you're going about in an appropriate manner, as well.

Good to hear some about the .277 offerings, keep us posted.

I just got in some for shooting and loading. Use 150 grain bullet reload data, and you should be fine.

I got some in, but haven't loaded them yet. I will be using H4831 as well. I'm hoping to get that project rolling here soon.
