My go to load for my M&P 15 is 23.6 gr of Ramshot X-terminator with Hornady 55 gr fmjbt on top. Anybody else using this powder and bullet combo?

I use 25gr of AA 2230 which is the same powder as X-T with that bullet in my 5.56 chamber. Accurate list 23.7gr as "Start" for a 5.56 chamber.

LivewireBlanco, I had a pound of X-Terminator in early 2012 and the load I worked up was 24gr with the same bullet. It was right around, or slightly under, a 1MOA load for me in my M&P 15 Sport.

It's a very accurate load for me but very little data on ramshot powders.

fyi, xterminator is exactly the same as aa2230.

Steve beat me to it.

Exactly as in same powder different label, or as in so close you can't tell the difference?

Exactly as in the exact same powder in a different bottle. They are both distributed by Western Powders. AA 2230 and X-T have been identical since 2007.

I've been using 23.0gr Ext. with a 55gr hornady soft point with pretty good results in my 16" bushmaster.

I use 24.2 grn of xterm under a 50 grn dogtown bullet. Jake, thanks for the tip. I wish there was a list somewhere of same powders with different labels. (if there is will somebody point me to it?)

I use 25.2 x-term and 55 grain sierra game king hpbt results in 3/4 inch groups... it's my favorite load

Has anybody used them on Midway's 55 gr Dogtown bullets, or a similar HP bullet with a flat base?

I used xterm with midsouth's varmint nightmare 55grn soft point flat base, but my rifle didn't like 55's much with any powder so I sold them.

with the 50 grn dogtowns I shoot about 1/2-3/4" with xterm.

1:12 maybe? I can't recall exactly. It's been a while since tested it. it's slow. It's a zastava mini-mauser.
