Any of you guys using N140 for .223?

I did a ladder test with once fired Privi Partizan brass, Fed Match AR primers and Berger 70g bullets. from a 24" AR, I found a node in the high 2800's with an SD of 8 and ES of 18. Loaded to just under max COL. 24. Primers looked good all the way up to 24.7 with only one slight swipe. I think 24.3 is close.

I’ve never used it in 223, but I have used it in 6 Dasher. It was about 10fps faster than Varget if I remember correctly.

Yeah it's fast and it meters great. Tried it first with 77g SMK's, and got a good node between 23.1 (2812fps), and 24.0 (2937fps).

that seems really fast for 77s, must be the magic of the long noodle barrel

Played with leverEvolution much? Was getting 2653fps with a 75 outta a 16" barrel. No pressure signs at that point

Agree, its fast, but zero pressure sings as far as I can see. It's always delivered fast speeds, I always attributed it to the extra 4" of barrel length, over what the mfgs presumably use for pubished data.

It's what I use in 6ARC with 105g Hybrids and it works well. The drop at 1k yrds is the same as my 147g 6.5 CM load.
