This is what I’ve heard from others. N140 for heavy 223 rem bullets and n150 for heavy 308s. And n150 is working well on the br as well.I've switch from varget to N150, it's close than N140 to varget I think.
308 and 6BR loads are within +-0.2gr from my varget load for the same Velocity.
But, for 223 loads, I think N150 is not optimal.
Went from varget to N150 in my FTR 308 200gr loads and it is shooting great.
I would certainly give it a go in a 223 with heavies seated long.

I switched from IMR-4831 to Varget in my 30-06. I'm going to try N-160 in my 240 Weatherby, along with H-4831SC, replaced it with Reloder #26.Who’s swapped from one to the other? I’ve read some people have landed back at the exact same charge after working loads up in the same rifle?
Any truth to this?
I’m planning on swapping my 223 from varget to n-140 in the next week or so… shooting 85.5 bergers.
I picked up a bunch of N140 to replace my almost gone stash of 8208 (Ive got through 32lbs of that).
First impressions are good but I have found that it wont generate the same velocities as 8208 (not super surprising as 8208 is higher in the burn chart).
I have even went to compressed loads which I generally avoid and it was *just* making the same velocities as my 8208 load without compressing. I settled a load 0.6gr less (not compressed) as it shoots consistently well but I am giving away 50fps or so.
It kinda makes me wonder if I would have been better with N135 but I know from watching Ultimate Reloader that he very successfully reverse engineered an N140 / Berger factory load with amazing results that N140 is a solid choice.
Hands down the best load I have found in this rifle has been D8208 (have 10lbs or so of that), seems to shoot phenomenal with 75gr or 77gr bullets. It has been said that D8208 is hotter and loads should be reduced, this is indeed what I found, I had to reduce around 10%, I wouldn't want to try the same load as I had for regular 8208 or it may result in a bad day.
Haven't tried N140 in the 6BR yet as I still have a bunch of Varget and it has been excellent but at some point I will give it a whirl.
You must be referring to 6BR with that amount?Try N150 series 2023 and up, might surprise you, 29.7 for me,
In what CARTRIDGE ? 29.7 grs N150Try N150 series 2023 and up, might surprise you, 29.7 for me,
In what CARTRIDGE ? 29.7 grs N150![]()
The burn rate charts say otherwise, and I checked the speed of both to verify this from the same barrel on my T3X, chambered for 223, with 77 grn Sierra MK bullets, using my Garmin.N140 is slower burning than Varget, in my lot #'s
