Need N570 loads for 300 Rum please

[Mram10us]

I got my hands on some n570 and want to try it with 215s, 225m and 230 smk or berger. Any load data is helpful. Using bertram brass and f215. Thanks

Any updates on this load/ combo?
Thanks

Yes sir. Settled on 90.9 N570 with 225s in a ladder at 300 than did a seating depth test at 300. Load shoots great out to 1468 so far. Haven't taken it further.

I'm amazed this powder keeps getting ignored. VV24N41 is one tick slower burning than N570. I have been using it for years in my 264mag, 26" Bbl. 140 gr bullets 3228 fps with no pressure problems. Many years shooting this powder & load. Perfect....

I'm ignorant to this powder. How is temp stability? Any downside? $40 cheaper for a 8lber is nice

I have been using VV24N41 for a good 8 years. Have hunted with it from mild to extreme cold (single digits ) temps . Never had the slightest problem. This is a powder developed for the 50 BMG.

What velocity did you end up with here?

I picked up some 245 Bergers to see if I can get the velocity high enough to beat a 215 enough to make it worth it.

Found some accuracy with 90 gr of N570 and a 215 Berger in my RUM. Have not chronoed yet. COAL was 3.841"

What velocity did you end up with and the 225s?
