2000-mr powder with 55 grain bullets...can it be had?

[Scoobys_piece]

Read that 2000mr can only be used with heavier bullets...Don't know if anyone has tried using it. Also, what about Accurate 5744.

Seems that I got my powders mixed up.

Should I use 5744 for .223 55gr bullets?
Should I use the 2000mr for my .308 loads

I have no idea what to do, powder is so hard to come by, but don't want to booger up loads and get myself in trouble. Thanks for looking and take care.

The best way to not booger up loads is to take your time and be safe. Start low and work up, you never know how your rifle will like a powder until you try it.

Thinking about 25gr 2000mr to start and work up in .2 increments..Many thanks. I'll post groups...no access to chrono. Take care and thank you again.

OR 11.5 of 5744.

2000-mr website only lists heavier bullet weights, but thinking that this is a relative new powder, guess data is not yet avail.
