[Balljoint]

Was able to pick up some of this ammo 55gr. FMJBT anyone know what the powder load is in this ammo was thinking of pulling some heads and seating some 77 gr Mks

It's not commercial powder. You can't duplicate it. Pull the bullets by shooting. Load the heavier bullets using published loads.

[Balljoint]

Think I'll pull the bullets save powder for later and load with Varget

[helotaxi]

Use the powder for fertilizer. You don't know what it is.

[Balljoint]

Have to give it some thought about the fertilizer still some one on another form could know what it is

[rez187]

agree should shoot then reload, powders are industry kept secrets and its safer to not get yourself in trouble.

Factory loads use a blended bulk powder that is not available in canister form to the public. The ammo companies won't release any information on the powder used or the blend.
