Nosler Brass, Nosler Bullets -- What Powder and Primer?

[Jarhead37]

Loading for a .223 Rem AR-15, 20 in. bbl, 1 - 9 twist. Total novice at
this small case rifle cartrige loading business. I just bought 300 nosler
brass and 300 nosler 60 gr partician bullets. Trying to decide on powder
and primer choices. Like what I read about Benchmark and Varget in this
cartridge: consistency over temperature range is important and both of
these are reputed to burn clean and provide good accuracy. Which is
better? Should I buy pound of both and see which one the rifle likes?
What are some recommendations for the best primer? Both of these
powders pretty well fill the cases, and I will hunt coyotes in December
in Utah, so the temperatures will be low; do I need a magnum primer?
Given the limited choices in the stores, I may have to "make do" with
whatever they have, but I would appreciate you recommendations for
which primer you think is actually the best one, and also the best one of
those that the stores have in stock. Thanks!

You gotta give them both a try and see what your rifle likes.

Pop's right, for the ultimate solution... have to try combinations of compinations. I would, however, buy one powder and see if you can get a good load with that before buying the second (or third, or...)

I use Varget with Winchester primers in my 223 and 22-250; both give 1/2"MOA results, although with 52 & 53 grain balls. Haven't tried other primers with either; I got good results with the 22-250, so started with the Winchester primers when working up the load for the 223.

Personally, I would stay with the standard primer vs the magnum - unless you can't get decent results... then you have to start changing components. I also load .020 off the lands to begin (and stayed there with both).

Just thinking... Varget may be a little hot for a 60 grain ball (?); I couldn't get the accuracy I wanted with a 55 gr ball in my 22-250, but might just be my rifle. Still, you might consider something a little slower - I'm sure others will have some ideas.
