55gr GMX in .223 Rem or 5.56?

[Scrumbag]

Hi folks,

Anyone got any load data for the 55gr Hornady GMX in .223 Rem or 5.56 NATO?

I'm thinking of using Ramshot TAC as the the powder.

Best wishes,

Scrummy

I use TAC in 55gr bullets all the time , it's actually all I use... I load FMJ rounds 24.5 to 25gr of it... That puts it in the 5.56 range... TAC will really push them so be careful... You can find Ramshots reloading data free on their website... To me their data can be very hot , once again be careful...

Thanks!

I use TAC with Hornady 55gr FMJBT and 65gr Sierra GameKing SBT so works with those. Also about 25gr seems to be about the magic charge weight for my rifle with pretty much any bullet I have tried with it.

Does anyone have an idea what Hornady's manual says?
