X-Terminator Powder

[Velocity]

Purchased 2 lbs. of X-Terminator and 300 Speer 90 gr. TNT HP projectiles today. Also purchased 300 New 6.5 Grendel cases (PPU) which use a large primer. They were the only cases I could find.

I did some searching on here for the X-Terminator powder and a few years back some members were using it with good success, until better powder came around. They were saying it's ok for the Grendel, just use projectiles 100 gr. or less because the powder is very fast. Just need to work up some load data now. And if the powder doesn't work out there's always my 5.56 rifle.

If someone has a good load for this setup, I'll be happy to look at it.

I started this Grendel project back in March when I first ordered my barrel then started to order everything else. My barrel showed up in late August and now my rifle is complete.

IIRC some posts on here have said that 2230 and Xterminator are the same powder... If so then 2230 load listings might give some insight as well.

So work up loads whatever you shoot.

On the other hand, a post on the forum we love to hate, says there are a couple differences now as of Jan 2016:
"Accurate 2230 and X-Terminator were the exact same powder up until January 2016. Now A2230 uses a change in grain geometry to be much more temperature stable. X-Terminator uses a new chemical composition to limit copper fouling. Their burn-rates remain the same."

So work up loads whatever you shoot.

From Speer's online data for 90gr TNT bullets. Doesn't list X-Terminator but there's some good powders to use in this data.

Nosler data for their 90gr Varmaggeden bullet. Lists X-Terminator...

Forgot to add that Accurate 2230 and X-Terminator have the same load data in the Western Powders Handloading Guide 8.0. So I guess they are the same, or at least same enough.

I've had good results with the 90 TNT and X-terminator 30.0 and 30.4 grains with cci 450's...
Also my rifle is a bolt action Uintah upper...

Having shot around 2000 rounds of converted 7.62x39 brass in my 243 LBC, I can attest the LRP makes faster powders have their pressure peak come earlier since more powder initially ignites. I'd start a grain lower than normal and given the way that the pressure curve gets altered, don't expect to be able to achieve book max velocities you see for SRP brass. Some of my best loads have been around book starting load.

To everyone who came to help - Thank you!
Now to get some loads worked up, but first I need to properly break in my barrel.

Happy Thanksgiving
