Bear in mind that this load was showing pressure signs with slightly cratered primers, so I have since reduced the load by 2gn, but have not had the weather to be able to test this new load beyond 100m.
Treat
any other persons load as a vague guide only and work up from minimum, watching for pressire signs.
You only get one head, don't risk removing it by ambitious loading, you have to treat every rifle and every load as completely individual.
I'm still a total neophyte as far as loading goes, but the best advice I can offer from my relative ignorance is caution.
Best of luck.
Cheers mate. I was mainly interested in what powder you were using. 23.6gr was my best load for the RDF 70s using 2206H at 2.275". But by "best" I mean a 1.3" 5-shot group at 100m - though the spread was all horizontal (possibly a bit of wind) with consistent vertical height.
Conversely, I tried the same load with Sierra 69gr Tipped Matchkings - 23.6gr of 2206H at 2.275" with ADI brass and CCI primers - and shot a .400" group at 100m. Anything under half an inch at 100m is good for me.
The TMKs are also slightly longer than the RDFs (.980" vs .960" on average), so I don't know how accurate Nosler's BC rating is. Nosler has been caught out telling fibs in the past, and you can go to Bryan Litz's site and compare real-world BCs with claimed BCs here:
http://appliedballisticsllc.com/ballistics/Suffice it to say, Berger and Lapua are the most honest when it comes to quoting BCs, whilst Nosler appears to have the longest nose. Hornady and Sierra don't appear to be entirely truthful, either - though Hornady claims its new ELD bullets are doppler radar tested and are "honest" BCs.
It's a shame I can't get the RDFs to shoot, as they're much cheaper than the Sierras. I've got a one-hole load using Nosler Varmageddon 53gr projectiles with 25.2gr of BM2 in the same ADI cases with CCI primers, so I know Noslers can shoot.
