I’m on my last pound of Ammomart NRP104. Labeled as similar to IMR4350, start 2gr lower. Is that the 47N ? Works lovely in .270 and 30-06
No, but it's very similar.
Most of us that picked up the 47N had issues with it after about ten years of storage. It broke down and had to be thrown out.
Tom sent me 21 pounds of it, along with the components needed to build up ''safe'' loads in different rifles and I really liked it. IMHO, it was N160 and I found that the loads were directly interchangeable.
I ordered another 21 pounds and Tom sent me 30 pounds in one big bag in a heavy cardboard drum. It was around $8/lb shipped.
Excellent powder, extremely consistent and gave some of the best accuracy and velocities in everything from 243Win to my 338-06 rifles. It was very good with medium weight to heavy bullets. Best with heavy for caliber bullets.
I still have a couple of pounds left, that for some reason didn't deteriorate.
I was a bit worried about it and almost threw it out.
Still I was curious and set it aside in the magazine and forgot about it.
I noticed it last spring, after putting together an 8x57 and looking for some powder to fireform some cases.
It gave 2500fps out of a 23.5 inch bbl with 200grn Nosler partions, over 57.0 grains and CCI250 primers
I didn't stick with it, because it works so well in the 338-06 that I'm saving it for.
I went with H414SL10, which is also a Higginson surplus powder that was excellent and is a bit slower burning than W760/H414 but more consistent and not nearly as temperatue sensitive.
