N568 Any experience with it?

[Wrenches]

I purchased an eight pound jug of this a month ago when there was a big drop. Not much load data out there and I want to use it in my 300 Win Mag.

Most people i know are using it with great success including myself, most common in .284 cals, 7mag, 28 Nosler . Don't have any info for .308 cals though sorry

It appears to me to be kind of an odd ball. Looking at the VV site it has less bulk density than either 560, 565, or 570 which are 960 and the 568 is 907. Again 560,565, and 570 have 4000 J/E and 568 only has 3850. I sure more loads will come in the future but for now the VV site lists very few.

It's easy to load for, I have had good luck with it in most magnums.338 lapua, 28 nosler, 300 prc, 300 win.

This is a tough question! It appears to be a new powder and I haven't seen any load data on it other than what Vihtavuori recommends.
I guess you need to start there and work up some loads to be one of the first pioneers. I assume that you are aware of their web address; (https://www.vihtavuori.com/reloading-data/rifle-reloading) You can find everything there you want to know.

Check VV website. There is plenty of data. Id send some but no idea what bullet you are using and my crystal ball doesnt work.

Ladd, interesting data on your loads. At what point did you see signs of pressure?

 

[skipglo]

I laugh everytime I see these threads! Hmmmmmmm...powder shortage...I wonder why?. LOOK A JUG OF POWDER....RUN...BUY IT..... oh boy I have powder.....wonder what it's good for? ......and the shortage goes on!

Agree. Think people buying to make sure had something close to what they normally use. If powder could be shipped by anyone without hazmat think the powder liquidity that would give people would take the pressure off the "shortage". I know I bought some in case ran out of what I normally use, then got lucky and got my preferred powder. I could sell to people looking if not for hazmat. Just a worthless comment.

I ran out of room in the case before seeing pressure. It is very consistent powder.

I havent had time to fully experiment w it, but it does have less energy content than N570 and N565. Those will likely give you a little higher velocities for the same pressures. To me, the big advantage is possibly its more accurate metering it, and I have anecdotally heard that it seems to give perhaps a bit more accuracy or
consistency in grouping maybe for that reason.

It is closer to N570 than to burn rate of N565.

I tried a bit of N568 yesterday just to see how it worked in my 7mm Rem Mag with 160gr Shock Hammer bullets. Not the best test since I used Large Rifle Primers instead of Magnums. I think the velocities would be higher if the Magnum primers had been used.
