I’m looking for load data for Winchester 748

[Cmmatijevich]

Hey guys I’m about to finish up my build and I have a lot of win 748 and I’d like to use a few other powders I have an abundance would be Ramshot Tac and Win 231 if anyone can help even just for a starting point I’d appreciate it it using 150 gr pojectiles.

And your not going to find load data for the 300 Blackout for Win 748 or TAC as they are way to slow burning for the small 300 Blackout case.

Win 231 on the other hand is way too fast burning.

I suggest you stick to powders actually recommended and tested for the 300 Blackout and 150 grain projectiles, such as:

Hodgdon CFE BLK
Hodgdon H110
Hodgdon Lil'Gun
Hodgdon Trail Boss
IMR 4227
Winchester 296
Accurate 1680
Accurate 4100
Accurate 5744
Accurate No. 11FS
Ramshot Enforcer
Alliant 300 MP

A little bit of google foo or other queries to educate yourself on the proper propellants suited would have been instructive. So much good info, including data in published form such as Hodgdon.
