Varget vs N140

Temperature Sensitivity of Powders for .223 High Power Service Rifle

Too bad IMR 4166 got discontinued. I have 2-3 lbs of it and wont bother doing load work ups on it…

As for the OP, give Winchester Staball Match a shot. It’s a good powder that matches velocities with the same charge weights and can get higher velocities when desired. Accuracy may or may not be at the same powder charge as Varget. I’ve done a fair amount of testing on the two powders head to head.

So you're saying N150 is closer to Varget than N140? Just asking because Varget shot well in my 223, 6.5Grendel, 6 BR and I wanted to try it for my 22ARC

not EXACTLY. or yes EXACTLY.

I am saying that Laurie Holland is getting those velocities:https://www.targetshooter.co.uk/?p=3856 with 223REM and 77gr bullet.

you MUST understand AND REMEMBER, that powder burn rate or velocity is VERY CARTRIDGE and maybe BULLET dependent. you cant say if you have Varget faster than N150 in 223REM, that it will be the same in 308WIN. it can be that Varget will be slower.

the same is for temperature sensitivity. it is HEAVILY CARTRIDGE dependent. in some cartridge Varget is very temperature insensitive, in others is more sensitive.

remember this, because people give wrong answers about those topics!
