Opinions on 300 Blk with 125gr Sierra Pro Hunters

Got my daughter a 300 Blk for deer season this year. Just got it put together last night. It is a PSA 16" rifle so we haven't got to shoot yet as I have to get a scope mount for it.

Have some factory Sierra 125 Gamechanger rounds for it. that I bought pretty cheap I figured would be good for her.
Today locally there was a guy selling a ton of Reloading stuff and I picked up a couple boxes of Sierra Pro Hunter in 125gr.
In looking in my older Sierra Reloading manual it doesn't list the 300 Blk.
In looking at IMR online it shows quite a few loads for the 125s but for the Pro hunters (SBT) its showing only Accurate and Ramshot.
I have some CFE BLK powder.
But the only thing IMR lists for the CFE BLK is the Nosler 125 BT. Yet the Nosler site doesn't even show the CFE BLK for their 125 BT.

My question is would I be ok using the load data for the Nosler 125 BT?
It has a starting load of 19.0 with a Max of 20.0.
 
Cfe Blk, 1680, H110/w296, lilgun will work. 110, lilgun higher fps and efficiency (what I use for 110 vmax or 135 FTX). Cfe Blk shows compressed which is OK, it like just a tad of compression. Biggest concern for different bullets is seating depth, effects pressure toward max loads.
 
You can compare bullet lengths and see if they are similar. If they are, you’ll be fine. Those little 125s are very effective.
 
I have given up on the 350L
It will get rebarrelled into a 6mm Arc soon.
Have plenty of other projects that need done first though.
You know how it is....So many projects....Only so much Money :D
 
I’m shooting the 125 pro hunters loaded with N110. Don’t remember the grains off hand. Killed a few pretty good sized hogs and a couple of coyotes with them.
 
Got my daughters shooting pretty well for her.
19 grains of CFE Blk did the trick
Only shot it at 75 yards which is about as far as I am going to let her shoot anyway so it should work well for her.
Running Starline Brass and Fed Primer.
 
I gave up on cfe blk. Use H110 or lilgun under 110 to 135gr FTX. My understanding is BLK is modified 1680.
edit: you might look at that 135gr FTX. SIL shot a hog with it, did good (shot high - broke spine). I got an armadillo @ 50 yds, BIG hole in the side. About 2200 fps. Deer rated bullet.
