Anyone using Red Dot in .223 or .243 cast?

Is anyone using Red Dot in .223, .243 or 6X45 and cast bullets? It is hard to find information other than mention of 8 to 10 gr in 30-06.

There is a lot of data out there. I have not used these so good luck. Take it slow and do some serious load development.

I have had very good luck with 2 different loads, both using the 55 gr bator bullet.

One with gas check and a little more powder, one without.

6.5 grs of Red Dot will get you in the 1800 fps area,and will shoot well also.
8.0gr. of Red Dot and a 55gr. FMJ is a maximum pressure load. It should be good for about 2150 fps in a 18 inch barrel, while generating around 50,000 psi.

My low velocity no gas check load was 4.6 grains of Red Dot, and seemed to be just below supersonic. Very quiet mild load, shot very well at closer ranges 25-50m.

Essentially I considered it a .22lr replacement. And as such I was looking for a dirt cheap load. So no gas check, 55 gr lead is not a big cost and with 4.6 grains a pound of powder is good for well over a thousand rounds. So primer and a couple cents worth of powder if you buy Red Dot by the 8 lb jug (or use promo)

The hotter load was more accurate at longer ranges, not quite as accurate in my handi rifle as factory ammo, but certainly minute of squirrel or groundhog at 100 yards.

Taking the center of the group as an eyeball all10 would have scored clean kills.

Yes Red Dot CAN be used in almost everything with some common sense and load development.

I used 6.0-6.7/RedDot/55gr. FMJBT for various applications. I'd happened into a bunch of badly discolored and (I guess) corroded projectiles that nobody could decide what to do with, so I cleaned them up & reloaded them using brass that had dents in the body or neck of the case. My mission was really to rehab the brass than to develop a sub-normal load. I started at 6.0/RedDot/55FMJBT, which worked on some of the brass, but not others. I finally worked up to 6.7/RedDot, which seemed to fully "unwrinkle" bent brass.
Accuracy was "minute of tennis ball" out to about 50 yards, but not much better (shooting from a Mini-14), which was better than expected. Seemed to iron out the wrinkles well, in messed up brass (which never seemed to fail faster than any others, when full-power loads were tried).
Interesting experiment in sub-par loads for .223 Remington.
