N 568 28 Nosler

[snowcreekkennels]

Anyone have a good starting point for 195 Berger in a 28 Nosler with N 568 powder.

I'd start at 79 gr. of N570. There's very little data on 568 from what I've found. But it appears to be slightly faster. So I'd drop a few grains from that. Load up from like 74-82gr in 1gr increments. You'll find out where pressure is in just a few shots.

I think I'd back the starting point down to about 69gr. I was helping a buddy with some load development H1000 and 195 Bergers in a 28 Nosler. I believe the powder charge we ended up with was 75.3gr. I know it's a different powder but should be relatively close.

Sounds like potentially dangerous advice to me. My 28 is maxed at 80grs of 570 under a 180VLD.

My apologies. I was at 82gr. N570 with a 195 and 84gr. with a 180VLD. That's the first time I've heard of someone pressuring out at 80gr with a 180. OP is probably no longer with us do to my starting load advice

Did you ever do any experimenting with the n568?

 

[snowcreekkennels]

No sure didn't I found some 570 and used that instead.

Thanks for the reply. I have a couple pounds of the n568. I guess I will need to be my own guinea pig.

I did that with my 7mm Rem Mag after contacting Vihtavuori ( who never responded ) and Nosler who suggested contacting Vihtavuori.

I read that the 568 was slow is the reason I never tried it. I came across about 10 lbs of 570 and decide it to give it the first try. Let me know what you come up with

 

[2buffalo]

Will do. Probably going to be two weeks but I will get on it. Lsherm gave me some information that will help.

Anyone have any good loads for N568 and the 28 nosler/195 combo. Unable to locate N570 but managed to come across N568
Looking to get the mid node in and around 3050 fps. Ive heard mixed reviews about it being slightly faster or slower than N570 and with the powders being extremely hard to find nowadays Im not looking to burn through a bunch. Touching is 3.75 coal and ive been running .02 off at 3.73 coal with N570 at 82 gr.

I cant p.m you not enough posts.
Depending on brass you will be 2-2.5 more grains with 568 than 570.
Start at your 570 load and work up.
You should end up around 3050fps, and about .030 off the lands.
