I am looking to reload Nosler Custom Competition 123 gr projectile using AR2206H for 6.5 Creedmoor.
The ADI handbook does not list 123 gr and the next closest bullet listed is 130 gr. The starting load listed for that bullet is 30.1 gr and the max load is 33.8 gr.
Nosler's load data for their 123 gr Custom Competition projectile using IMR 4895 (which is apparently an equivalent powder) is, starting load 35 gr and the max load is 39 gr.
That's a very big difference for an equivalent powder.
Anyone got any ideas on a safe starting load using AR2206H? I'm also open to trying AR2208 if anyone has any real world experience with that powder for a 6.5 CM.
Sydneywizard wrote:Thanks Bladeracer but I have been using AR2209 and the results are very unimpressive. They shoot <1 MOA at 50-100 m but once I get out to +200 m, they started spraying around a bit. When I first got the CM, I used the AR2206H as that was all I had on hand and the results were under 1 MOA up to 200 m, but then I read that AR2209 (H4350) was "the go" and ever since then, I have been trying to make it work.
In the meantime, I have checked that scope, rings, and base plates are not the culprit. All that left is to swap out that Hogue stock for a GRS but that won't happen for a few weeks. So, I'm going back to what worked originally for me.
Hopefully, it's not a dud rifle.

According to the guys who came up with the Houston Warehouse experiement, their findings from 6 years of accuracy testing was that there is no such thing as a rifle that shoots well to 100yds but "opens up" after that, or vice versa. If it shoots tight at 100 then it will shoot just as tight at 200, all things being equal.
Things that you could look at are your shooting technique and also reloading technique. I suspect that if your bullet run-out/concentricity is off then the issue my compound the further out you shoot but i am a firm believer that most people's issue with accuracy at range is their own shooting technique; but then, none of us really want to admit that, do we!
Not having a go, just food for thought.
A GRS stock would be nice. I am saving for one my self. My experience with hogue stocks is that they suck arse for anything but blasting pests under 150m you can bed & stabilise them but if you can save for a better stock then do so!
Sydneywizard wrote:Yes, I normally shoot the 140 gr but I have had some difficulty sourcing them regularly and I came across some cheap lots of 123 gr, so I thought it might be a good idea to develop some data on it. I also had the same issue with the 140 gr from the word go.
No question that I'm no Jerry Miculek but I'd like to think that I'm no flog either. I do shoot every week with my CZ 452 to keep working on my technique as that's the one skill that needs constant practice. My 223 with the same Hogue stock shoots MOA or better out to 200 m, so using that as a benchmark, I can vaguely assume that the CM should perform equally well in my hands. Is there room for improvement? Of course there is. Till the day I stop shooting, it will be a work in progress.
Yes, I did read that report on PR Blog some time ago and the conclusions were interesting, which make my issue even more puzzling to me.
I have also looked at my reloading technique and I have to say that I am quite fastidious with the quality of my output. I never reload more than 20 cartridges at one session, just so I don't get bored or distracted and I can concentrate on producing quality ammo. I have even gone back to reloading to SAAMI specs, to eliminate any variables in my reloads. I might get a box of factory ammo and use that to get some sort of a benchmark.
I do appreciate the "what about this" and "what about that" but you can see that this not just one bad session out on the range but over a fair number of sessions and over a moderate period of time. It's just very frustrating not getting the results one expects.

I use 40 grains of 2209 behind a 140gr Hornady ELD match bullet. 1 in 7.5" twist rate, 24" barrel. Prints 3" groups on 500m rams.
I use 36gr of 2206H behind 108gr Lapua Scenars for my 200, 300 and 385m targets. sub 1/2" @ 100m. Holds up all the way out.
Dave Emory from Hornady, (one of the blokes who came up with the 6.5 Creedmoor) recommends a maximum load of 39.2 gr of Varget, ( ADI 2208 ) or a maximum of 43.9 gr of H4350, ( ADI 2209 ) behind the 123gr bullet.
Hornady uses H4350, ( ADI 2209) for its match grade ammo.
