What are you getting for velocity?

I would be more concerned about accuracy the velocity to be honest.

Yes but what is accurate in your gun might not be in mine at the same charge weight. I was just curious to compare it to what I was getting with Lil gun.

Exactly. Just concentrate on getting accuracy. All trial and error in finding what works best for your rifle.

what seating depth are you guys using ??

I’m away from my data but I do remember the 150gr Remington PSPCL ended up at 2.220”. Being it was a flat base bullet, you can get away with it.
This was about the max length I was comfortable with of the bullet (or lack of) in the case for neck tension. The boat tail probably won’t work at this length.
I’m also doing a 150gr RN at 1.900”, same powder charge, in a 7 1/2” barrel.

Hornady lists 2.090” for their #3037 150gr FMJBT.
This is corrected from the 9th Edition that showed 2.220”.

Do you mind telling us what the 150gr BT bullets will be used for.
Are these bullets "pulls",military,etc ??
Being FMJ, I would guess NOT hunting bullets. Loading for the 300BLK, flat base bullets are your friend. So are bullets <131grs . . . especially for hunting. --- SAWMAN

I use Barnes 110gr Tac-Tx for hunting , I bought 500rds of the Hornady 150gr fmj/bt just for plinking and punching holes in paper .... just not finding much load data for a starting point ....

I bought the 150gr in hopes of getting a super cheap subsonic plinking round. I have come up with a few loads that stay subsonic and still cycle the action. Just need to load up some more and test for position sensitivity of the powder.

Hornady’s 9th (and probably 10th) Edition has data for 1680, 4227 and H110 with the FMJBT.
Hodgdon has data with CFE-BLK but with Hornady’s Interbond bullet, so the length is probably going to be incorrect for the FMJBT.
