223

25 and a half-ish grains of Xterminator with 50grain ballistic tips, Vmaxes, soft or hollow points gets about 3450fps out of a 26 inch barrel. If you have it on hand, use it. No need to look for another powder.
 
H322, H355, W-748, 2230 & Tac all work good with the lighter bullets. I've also used Varget, 8208 and RL-15 but mostly with the heavier bullets.
 
For the light bullets (40's)- Accurate LT32 is pretty hard to beat in most rifles we (my buddies and I) have tried it in. TAC can work pretty good with the 50-55 weights, as can 8208XBR (we run 23.0-24.1 with 50's) and Reloader 7 (we run 21.9 with V-Max). The LT32 is a bit pricy, but normally available. Great stuff. For 40's, LT-32, W748. Your TAC might really like 50-grain Varmint Grenades with 25.5 Also the Barnes MPG 55 with 23.1. - 23.9. It is wicked in a couple of the rifles. We found TAC to work much better with unleaded bullets than leaded in our rifles, so if you have any - give them a try. Use Barnes OAL recommendation and don't try to get them close to the lands, as they don't shoot too well that way as a rule. Work up - especially with the RL7.
 
I used xterminator for 40g nosler BT. Velocity was a get age of 3596 with good accuracy
 
I have had good to better results with 50-69 gr bullets with X-terminator. In several rifles, 23.5 gr behind a 69 gr bullet are best in class. As always work up, 5.56 level load
 
Ok thanks i always work up
How old is your lot of powder? Recently Western may have decided to take 2230 and XTerminator in different directions, but the old data was identical for both. This is a Nosler accuracy load @23.5 gr and the 69 gr bullet.

Ok thanks guys my lot of x terminator is old stock
 
I usually load 60 to 80 gr bullets. My goto’s are 60 vmax, 77 smk and 80 smk. Over time I’ve tried to simplify my loading components. Couple powders and a few bullets. I’ve also narrowed down calibers over time.
 
What bullets? What platform? I’ve got a 20” remington tactical and shooting 75gr bthp and n540 I get 3000fps. I was up over 3200fps. I generally stick with cfe223. But have been wanting to get into the Vihtavuori powders some. I use that load at the range on steel. I don’t know what brass life I can expect running that way. Granted it’s only about 200fps faster. But still. I’m running starline brass
