Thread: Loading for .300BLK

What’s everyone’s favourite off the shelf stuff for the .300? I’m getting one soon and I don’t reload, Both sub and super sonic.

Sub: hornady 190 sub-x

Nah Ive never tried the Lil Gun, Ive always had great results with H110 for both subs and supers so never really strayed from it. I used 2205 on one of my AR15 BLKs bit that was more of a gas flow issue I was chasing.

Interestingly Sierra doesnt have data for LilGun with their 125gr TMK but do have it for the 110gr and 168gr.

What is its case fill like behind a 125gr and what is the approximate velocity with a max load in a 16" tube?

I see hodgdon have it on their load data website, I did my development back in 2012.

Lilgun for me was better than H110 - 110gn vmaxs at 2500fpc max and 125gn 2450fps max I settled just below these maxs in a 16" barrel AR. Case life seemed ok being AR lost quite a few

Looking at ordering some 135gn FTX and ADI 300brass for a bit more development

I've shot a couple of deer with the 125's now out of my 12.5 ar. Both double lunged, pass throughs and clean if not spectacular kills. The first one got a second between the ears to hurry it along but it had only run 20m and lay down anyway, so would have expired.

I'm contemplating moving to somthing slight softer but will shoot a couple more before i make my mind up.

They shoot moa over little gun for me. Haven't chronied as Its a bush gun with red dot
