Cooper... nah not Melbourne mate, out bush, local town about 10-13,000 pop., one small LGS who has 'fixed' ideas (he'd be in mid 60's) and inflexible in many ways (see below). Thanks for the projie recommendations, and yeah, they too were on the list.
Confused the Speer purchase on that being what OSA/Aussie Outback rounds are loaded with, which get great reports from a range of rifle makes. I see now on second glance they are Sierra, but no 55gn listing for Sierra on the ADI data sheet.
(my bad). Will look again at pricing/availability of both once more.
Rod_outbak...Seems I'm stuck with the LGS for primer/powder combo's then, unless I want a 2hr return trip to a larger centre...
I like to keep it local as much as I can, but my LGS sure makes it difficult when he doesn't want to sell me what I want. Case in point, I am buying a CZ and he keeps pushing the Howa down my throat, likely as he has it on the shelf...and has to order the CZ in.
I have read reports where the BR#4 is also a contender for primers (among benchrest guys) and chose #400 for my list based on popularity, though as stated, my selections are not set in stone.
Reading your mates experiences I was somewhat confused by "..AR2206H is pretty close to AR2208 so it may also be a bit too slow." in comparison to 3000fps when the ADI chart lists 2206H/2208 as being from 1:12 a 24" bbl, mine will be a 1:9 24"....
55 GR. Speer Soft Point, Spitzer, Spire Point
AR2206H .224" 2.200" 25.0 grain
3176 fps 39700 cup 26.0 grain
3315 fps 49000 cup
55 GR. Speer Soft Point, Spitzer, Spire Point
AR2208 .224" 2.200" 25.5 grain
3174 fps 41300 cup 27.5 grain (C)
3384 fps 49700 cup
but then again, no listing for the Nosler projie & running a lighter load in a shorter bbl of manufacturer unknown...perhaps therein lays the difference? Also, I don't have access to a chrony, so it will just be a matter of which recipe groups best, regardless of speed.
It's a given every rifle will be different in what recipe/components each likes 'best', but due to $$ limitations, I figured i had a reasonable medium all round entry level combo to start out with to start my testing, I stand to be corrected.
Over time as funds allow, I can obviously change things up one at a time to see any variances, beginning with experimenting with the range of projies, then powders as most primers appear to be within set parameters to a degree with the least variety.
Glad to hear I at least got the brass well chosen...
Thanks for the input folks.
Cheers
