RL-15 RECIPIES...

[dancinzen]

hello, i have a 5 pound jug of RL-15 and i only have it marked for being used on heavier bullets(69gr and above) for my 223/5.56... can this powder be used for 55 grain stuff? if so how would i measure it?

My data:

75gr BTHP with 24.1gr R15 I load it max length for long range so its not for another rifle. But you can seat it for max mag length.

55gr with R15...27.0gr(compress). I did this with mild velocity but the best thing....BIG BOOM STICK! Huge fire ball when fired. Cool Factor.

These loads work for MY gun but it might not work for yours. If you decide to go with it, load at your own risk.

I recommend using a scale.

Ofcourse use a scale but I mean I don't have data to know how much gr of powder to use?

That's a better way to ask.

There is 62gr bullet data here:

By the lack of data for 55gr bullets, that's a sign that the powder is not appropriate for 55gr bullets.
