Discrepency in TAC load data

[450rydr]

I have the printed load data from Ramshot with a max load of 26 grains for a 55 grain sierra bullet in a .223rem. The PDF file I have downloaded says 25.2 grains. Which are you guys rolling with for a max load for a 55 gr bullet with TAC?

I assume you are refering to 223 Rem. We have been using 25.0 gr of TAC with the 55 gr Varmint Nightmare. Works very well with no signs of pressure in several guns. A lot of the AR guys are using 24.5 grs. with a 55 gr FMJ. We have been very happy with this powder.

i started my 223 load at 24.3gr and they work good so far but I will try working up to 25 or so here shortly to see if my groups still pull in.
