Vihtavuori N170 to replace H1000?

[BClrh]

Anyone have experience with N170. I am running out of H1000 and it has a very similar burn rate. Anyone had success with this powder? Temp sensitivity?

I am looking to use it in a 300NM running 215-245 grain bullets out of a 18" barrel.

I have a little bit of it but I haven't used it. Burn rate & characteristics put it really close to H1000. Just a tad faster than h1000 & just a tad slower than rl25. I would think it should would work great for what you mentioned.

Also try RL26. Works incredibly well in my 300 NM with those bullets.

I have about 5 pounds of n170 but have not tried it yet. Anybody know what it does on throats versus H 1000?
