6.5 Creedmoor Load Development

[Non-Typical]

I had a great load developed using RL17 and 147gr ELD Match bullets. RL17 has been hard to find lately so I started working on a new load. I started with H4350, 140 gr ELD Match, Lapua brass and CCI #450 primers. I loaded 5 different loads starting with 40.2 grains and increased 0.3 ending with 41.5 grains. The 41.5 was the best with a 3 shot group of 0.236". Next I'll probably chronograph a 10 shot group and then do the same process with StaBALL 6.5.

41.5grs H4350 is a very popular load that seems to work across most rifles.

In my 22" barrel it was 2643fps average with low es/sd in a friends 24" barrel it averaged 2717fps with low es/sd.

I am starting to develop a load for mine, going with H4350 and the 143gr ELD-X as I just hunt with these. I have the magneto speed with a mount that doesn't touch the barrel so will chrono when I shoot the ladder. I'll pay attention to the 41.5gr load as that is what I've read does well, probably load a few extra of those and use them for zero as I'm mounting a new scope too.

Edit; I actually misspoke here, I have 39.6grs as optimal, and 41.5grs as max on the load data I have, 41.5grs was for the ELD-Ms which I was looking at using, to hunt, since I could not find the ELD-X at the time, but I am good now.

Without looking in my data, pretty sure I am running 42 grains imr4350 under 143 grain eldx. Excellent accuracy, and great performance on deer.

I'm still testing, put on hold for other things currently, a load of StaBall 6.5 under Hornady 153 gr Atips. It was promising before I started chasing another squirrel. My pet load tho is 44.5 gr of Superformance under the 140 gr ELD-Ms. That load is not a barn burner for speed, but holds sub MOA accuracy out to 600 yards, and I've shot .6 MOA groups at 1000 with it.

Try some RL26, if you can find it.
