Anyone using n568?

[steve19]

I've made some loads up for a 6.5prc and I'm getting 230+fps less than I'm expecting.

Vit reckons 2850 on max charge. I'm getting 2620

Looking online a few people state side have had similar issues with this powder, just wondering if anyone on here is using it and having similar issues?

I only used it because the vit manual said it would give me the speeds I wanted.

Similar barrel length?

If you ain't getting the velocity, keep stuffing powder in until you hit pressure.
What bullets out of interest?

what bullet, what barrel length - you should be getting 3k - suspect 568 too slow for your application

Book is 24" mine is 26"

No pressure signs at all, there's no room in the case to get it in!

I'm more than likely going to be switching powders. It's just annoying that the vit data is so far out for that powder. I use vit in everything and the load data has always been spot on.

26" and 147 eld
It 100% is, I'll be switching to something faster for sure.

Just wanted to know if anyone else had used N568 and had the same results.

Always thought it would be too slow for 147's. N560/565 should give you the results

Tikka factory barrel? I’m getting slower than expected velocities in a 26” Tikka 6.5CM.
On powder I would have assumed n560 would be good for 6.5PRC

What powder charge are you using?

I'm probably going to get some N560/565.

I'm running RS76 with 153gr A-Tips and getting over 3k in a 26in barrel. If you want to stick to Viht, I'd go N560.

That's probably what I'll do. I use vit for everything else as I can consistently get it.
The vit data is spot on for everything else, I'm just annoyed it's so far out for this.

59.5gr. No pressure. Brass is on its 6th re-load.

Tried that. SD’s doubled.
