H1000 VS N570 ( 28 nosler)

[dave_halsey]

So I just placed an order for a load development pack from Unknown Munitions out of Idaho and in said pack of 50 rounds one ladder of 25 will be with H1000 and the other 25 will be with N570. I'm curious if people have used both and compared the performance as far as velocity and temperature stability? And just your personal opinions on how they both will perform? I will be testing both out of a custom built 28 nosler with a 26" proof 1in8.24 twist and a dead air sandman ti suppressor on the end pushing the 195 berger eol ( C.O.A.L. of 3.700). I realize this is a reloading forum but due to time constraints( really good rifle deer tag coming up) and the local store not having any of the reloading components I had to go through a custom loading company. Thank you all and happy hunting!

N570 and h1000 share a pretty similar burn rate. We've had awesome results with both, but N570 seems to push the heavys faster with less pressure. Ive also read that n570 is better for temp stability.
Currently using the 570 in a 7mm stw with the 195s.

N570 is very consistent. I am pushing the 195 @ 3050 with very excellent accuracy. I have a 26 inch proof and really don't want to burn it up so I stopped at a very nice spot.

I wouldn't use anything else in my 28 nosler but n570 and 195s.

I tried h1000, r33 and n570. I ended up with great accuracy and decent speed from the n570. 195s right at 3000 chronoed, not guessing

N570 would most likely win with the 195's.

Does the n570 help a lot with the barrel life? It's going to be a hunting rifle so I wouldn't guess more than 25 shots a year max ( after I settle on a load).

I like N570 but heard it burns real hot. That said 25 shots a year your barrel should last a long time. Just fire your shots slowly no need to rush.

I will take accuracy over speed any day but 3000fps with a 195 will be a slayer.

How many grains are you guys shooting in your 28 noslers

N570 will run 3100-3150 in the 26" cf proofs with the 195s. Low ES, Pretty temp stable, just wish it would meter through the A&D.

Do you think the supressor will give it a few extra fps?

 

[CA48]

It depends on the suppressor you will be using, my HTA doesn't.

 

[WildBillG]

CA48 you are right it does not come out of a powder dispenser very well. My Redding would not even dispense a half a charge. I ennded up using a Lee powder scoop. At least it went through the powder trickler ok.

 

[CA48]

I weight it through a charge master then check it with the A&D.
