I'm looking for a starting load using AR2209 for 210gr out of 308W. ADI does list anything. Here are a couple specs I'm starting with.

Estimated overall cartiridge length will be 3.159"; to give

jump - 0.010"

Ogive to cartiridge base - 2.415"

Trimmed case length - 2.003"

Shank length - 0.465"

Seating Depth - 0.164"

LFAD gives about 45.2gr for 45763 CUP.

Any info would be appreciated.

It's not a starting load by any means but what I'm using is:

Sierra HPBT MK #9240
Winchester cases - median weight ~157gr
Case trim length 2.010"
Base to ogive 2.477" which is just kissing the lands when the barrel is first chambered
Federal GM210M or CCI BR2 seem to be interchangeable without effect
50.4gr AR2209

This gives totally effortless extraction in my Davies and RPA Quadlock actions and heads downrange at 2685fps. I use a lighter load in my Omark.

I'll repeat that this is NOT a starting load and remind you of the standard starting out precautions. Particularly take note of the case weight. Winchester are quite a bit lighter than other popular brands of brass - which is why I use them.

Good luck and please report back.

Thanks Barry

I'll start 10% under which corresponds very close to the LFAD load. I'm using them in my S&O Shorty in a couple of weeks. I think +2400 fps out of her 26" barrel with a 1:8" twist would be realistic. I use my old Winchester brass, but I bought some PMC LR primers to try today.

Sorry. Should have said in my previous post that I use Krieger 32" 1:10 barrels.
