Thanks,

Sure, Overbore got me started with some recommendations (and they were spot on!). I'll paraphrase his advice to me (all of which I have proven correct).
He recomends 2 powders.
For 175gr bullets and above he uses H4350
For under 175gr bullets he uses Varget.
He recommends a mild primer with Varget (CCI BR2's)
I found (as he later confirmed) that CCI BR2's are not to be used in COLD weather, as they are too mild to give good/consistent ignition. I found this out in temperatures from 20 degrees F and colder. Overbore recommended Federal 210GM for cold weather loads (not the 215's).
My best loads are as follows.
Load #1)
Norma Brass, 165gr Hornady boat tail spire point (#3045), CCI-BR2 primer, 60gr Varget powder. I have these loaded for a minimal jump to the lands and they will consistently print .3" CTC or better. I don't know what the velocity is (I've never remembered to shoot them when I had the chrono set up). This would be a GREAT deer load, as the bullets are REALLY cheap and super accurate. Velocity is probably around 3000fps from a 26" barrel.
Load #2)
Norma Brass, 200gr Nosler Accubond, CCI-BR2 primer, 62gr H4350, Loaded for minimal jump to lands. Shoots consistently at or under 1/2" at 100yds.
Average velocity is 2844fps from a 26" barrel, with extreme spread of 24fps for 10 shots at 80 degrees outside temperature.
I also loaded from 60gr-62gr this winter with Rem 9 1/2 primers and it shot very well in the cold weather. I believe the Rem 9 1/2 primers are the next step hotter above the CCI-BR2's.
Load #2 is getting up in pressure a bit, so please work up to these loads yourself in your particular rifle.
Hope this helps.
AJ
