For those using 150gr fmj/bt in 300blkout would you mind sharing some load data that works for you .... I will be using 16" AR ....AR 300 blkout.jpg

I run 15.5gr of H110 in my 6.5"300 blk. Work well.

I just shot a test load last night of Lil gun from 15 to 17gr. This was giving me velocities in the 1800s from a 8.5" barrel. I was seeing some flat primers on the higher end so be careful.

Try H110 at 15.5gr. That's what I use.

What are you getting for velocity?

When I was playing with the round. CFEBLK shines with the heavier bullets. H110 for the 100’s-125’s

19.0gr of 1680 is getting 1870fps in my 16” barrel with 150gr Remington PSPCL.
Not at the max either.
