223 Cast loads

[Hick]

For all my 223 loads, I use a gas check, size them to 0.224 using a Lee push trough sizer then just tumble lube ( one coat of Ben's LL - a mixture of that special Johnson's liquid wax and Alox). This gets me to ~1700 fps with no leading.

I have been using 5.0 gr Unique with the Bator bullet, Getting around 1650fps according to my cousin chorny. From a single shot small martini

What are you guys using for lube, and how far over grove diameter are you going?

I am thinking with the Lee 225-55-RF that I will use Lyman Alox lube and gas check them.

I lube with 45-45-10 prior to sizing and gas checks. .001” over groove works well for me, a little bigger does no harm. Final lube is done in a pan with a homemade concoction similar to WWV lube. I’m sure Alox or 45-45-10 alone will be fine.

I have been using Lee Alox and shooting them unsized . have not been using a gas check at these FPS, getting squirrel head size groups at 50 yards.

that sounds like a nice squirrel load, will have to try.

Hope you get the same results, has worked great for me and in my cousins Savage Axis

My lube is a mix of 75%Alox ( the 50/50 kind ) and 25% LBT blue lube . Only lube one ring no matter if I use gas checks or not . Oddly enough I can get away with using less powder when using a gas check .

If I wanted only a thousand feet per second I'd use Bullseye and drop the charge a good bit .

A"LIKE" button sure would be nice!

I was just lent a very nice set of MP molds dropping beautiful HP and solid "hornet" bullets.


Unsure if they will make it i to 223 cases. But my Hornets and Bees are gonna really enjoy them!!


MP surely knows how to make a beautiful
Mold!

I have been using RCBS 22-55-FN weighs 59 grains using straight ww and RCBS lube.

I have been having good luck with 7.0 grains of Unique in a 1:9 barrel.

I recall doing some testing with 700x and hornet boolits (Lyman 225438). I used from 6-7 grains of 700x to get from 1900-2200 fps, 8 grains of Unique gave me about 2300 fps. Very low recoil with the little 44 grain pill. I believe that was out of the TC Encore.

I use 5.7 grains of Accurate # 5 behind a Lyman cast gas check 415, 55 grain grain bullet. Lee crimp die for all.

Scroll down to page 129 for Red Dot loads in 223 for boolits from 37 grains to 54 grains. Don't overlook the 748 loads, I use that powder for 223 in AR's with a 70ish grain MP boolit.

What charge do you use for the 70gr? I am looking to develop loads for that wgt bullet. I am using a Savage 12 bolt action though
