Anyone using CFE-223 for 308? Looking for Dillon friendly powder.

[Danattherock]

Im looking for Dillon 550 friendly powder to push 155 bergers or JLKs. Just ordered a Brux 26” MTU contour 1:10 308 barrel for my Curtis Vector switchlug action. I will mainly use 6 and 6.5 creed barrels, but will use 308 to train. While targets go to 1000 yards, main area of interest is 400-700 yards. Thanks for any thoughts.

Dillon 1050 progressives metered IMR4895 into new 308 cases primed with Fed 210M's and seated Sierra's first lot of 155-gr. Palma bullets that shot about half MOA at 600 yards. The 3 to 4 tenths grain spread in charge weights around 45.3 grains was not an issue in a couple dozen barrels with different bore and groove diameters.

Metering 46 grains of Varget will probably do as well.

I would take a look at 8208.

It is the only powder that I load under 150 Interlocks. 2924 fps from my Ruger American and 1/2 moa.

look for a load WINDOW vs a specific weight. dillon's have been used to produce excellent long
range ammo. one more powder is accurate 2520. built for 308

I've used Win-748 and it's a good powder for the 308win.

Use hotter or magnum primers with ball powders.

I've tested different primers with W-748.
Best to worst...

215m
WinLR
210m
cci200-br2 not even worth trying.

Thanks for the insights guys. This will be my first 308, wasnt aware that 8208 was a good 308 powder. I have a few jugs of it as I use it for my 77 smk load on Dillon 550, and just had a 6.5 Grendel built with same intentions.

Read old thread here suggesting CFE-223 produced good velocities, 2900+ with 155 gr projectiles. I know it will meter on Dillon pretty well, +/- 1\10 gr I suspect, as does 8208, if not better actually. And I have ten pounds sitting around, so there is that low hanging fruit analogy.

I also have a good supply of H335, as I use it on Dillon for 55 gr AR15 plinking loads. Saw on Hodgdon site that its used in 308 also, lighter pills at any rate. But velocity was much lower, 2650-2750 as I recall.

Thanks for any further suggestion.

If you haven't done anything to your measure, you can do a lot to improve the accuracy of the measure by polishing the interior of the cone. I load only for hand guns on mine, but it significantly improved the accuracy of dispersing the hard to meter powders like Blue Dot and Unique. Some folks also add a baffle in the tube to improve consistency.

I agree. I found XBR8208 to work very very well in the dillon 550 and 308 with 125 TMK and 178 ELDX.
There is a narrow window for the accuracy node in my AR10 and the dillon will usually keep the powder -0.1/+0.1 grain of my target weight.

VV N140 works great for the 155g in my Bartlein MTU 1:10 and meters well in my Dillon powder drop.

Here's some tricks. You can take some metal polish (Semichrome, Flitz, Maas) put it on a felt nib, chuck it up in your dremel and polish the bottom of your Dillon powder hopper and powder funnel throat. That really gets everything metering better. Also, take a dryer sheet and rub down the inside of the powder hopper before you make a run. Static seems to be the enemy of consistent powder drops.

The one powder I've had no success getting to meter in progressive mode on my 650 is IMR 4064. Feels and sounds like I'm grinding coffee. Throws often vary over 1.0g

Edit: Oh, I see @jepp2 beat me to it on the polishing trick

I commonly refer to it as Lincoln Log powder.
