Just looking for a place to start at. I know a lot of people swear by this powder so I'm giving it a go. I appreciate the help in advance.
I'm looking for an 8208 CCI 450 lapua brass recipe for 123gr a max

28.5gr 8208
CCI 450
Lap brass
123 Amax
about 1.5 thou of neck tension, no crimp
COAL 2.268
This is a hummer of a load in my rifle... yesterday I made 4 consecutive hits on my 12 inch steel at 950 yards, with 34 MOA of adjustment. I forgot my rear bag, so if I had that I am sure that it would have been even better.Last edited by Guest; 07-24-2011, 03:43 PM.

Assuming case capacity of Lapua is near that of Hornady brass and assuming CCI450 primers are hot like Remington 7 1/2s, here's what works best for me.
65 Deg F
123 Amax @ 2.29 COL
Hornady Brass
Flash Holes Deburred & Primer Pockets Normalized
29gr 8208XBR
2602 Avg velocity (24" medium contour AR Stoner barrel)
SD 13
100 yd Groups like the one on the left:
The fliers were courtesy of the fellow next to me banging away with a Sako 338 Lapua Magnum.

600 yds 10.6MOA (I use 13 MOA)
800 17MOA (I use 20.5)
900 20.4MOA (I use 25.5)
1000 23.9MOA (haven't tried yet)
How come there is such disparity?? Just when I begin to think I am starting to understand this stuff I end up back at square one.Last edited by Guest; 09-04-2011, 05:13 PM.

What G7 BC are you using for the Amax? I've only seen G1 BC's listed (.510). If you're just plugging the .510 G1 BC in as a G7 BC you're going to get way better calculations than what will really happen.
edit: when I plug all of your info in and use a .510 G1 BC, it gives me 26.2 MOA for 900yd, much closer. And to be honest I'd only expect calculators to be within 1 MOA (if everything is done properly) regardless.Last edited by Guest; 09-04-2011, 06:46 PM.

Anyone know the G7 BC for the 123 AMAX??
