338 Norma mag Improved data

[Rhovee]

I am getting a new 338 NMI soon. Going to be shooting the 250 elite hunter. Curious if anyone has this round, and if you could provide load data. I'm thinking 90 grains to fire form. And load up from there with H1000

3 year old thread but curious what you ended up for charge weight fireforming with 250eh? Have one incoming from Alex next week. Any data or suggestion you might have is appreciated. I was thinking 87g of H1000, jamming a 250eh about .015. Going to focus load development around H1K and 300otm, trying to stay away from N570. Just using the 250's to fire form.

I fire formed with 85 grains H1000. Had a good node around 87 with 300's

Nice, appreciate the response!

What velocity at 87 gr?

 

[Rhovee]

That was in low 2700's. N570 and 300's worked best at 2810 in 24". Or 260 hammer hunter. H1000 around 3000

Thank-You (that 260 HH gotta punch)

I've got a sample pack of 260 Hammers if you'd like to try them.

As of yet, I haven't got a 338... Next itch to scratch
