300 blackout and IMR4198

[Speedster00]

Is anyone using this combo? I really like it for my 223 but I cant find data for 150gr bullet for 300 blackout using 4198. I figured it would be a great powder and Im trting to achieve somewhere around 1900 FPS if possible. Can anyone help me out? thanks.

It might be suitable. It is close to to slow looking at a burn rate chart, and I wonder how bulky it is, as in how much would fit in the case.

I am interested as well.

Searching, it appears Lil Gun is the most popular powder and my local shop had it on the shelf today. according to this thread over at 300blacktalk, people are getting 2K-2300 FPS with it using 110-150gr bullets safely. Looks like I need to go get a lb of lil gun unless someone can run the load data for me and tell what Ill get with 4198.

Enforcer can do it as well. Link.

It looks like if I switch to the 110gr sierra RN #2100, I can 2400FPS with Lil Gun which would give me a reliable 200 yard bullet for hunting. zero'd at 150yrds, I would only have a 4" drop at 200 and still be at 1500FPS.
