N568 or N656 for 6.5 PRC

[Backcast88]

Picked up a Seekins PH2 last week in 6.5 PRC. I've bought Lapua brass and am looking loading 143 ELD-X or 145 TGK this season. I would like to go with H1000 or RL26 but with both being impossible to find I have found a local source that can get N565 and N568 for the time being.

Anybody have any load dad with the 143 ELD-X or even the 147 ELD-M and 565 and/or 568?

Seems 565 is the more popular route but I can get 568 a little easier so if it performs well I can certainly stock up.

N565 works great in two 6.5prc’s for us. H1000 has been available pretty often lately and tons of online stores offering free hazmat.

FWIW, I’m using 565 as well, and what I’ve heard from testing is 568 is slow in comparison.

I was disappointed with N568, too slow burning with disappointing velocities. H1000 has been great, N565 works well.

Sounds like 568 is slow. I've been seeing it that posed other places so that makes 565 the clear choice.

N565 in lapua brass is working very well for me. 20in barrel pushing 147s righ at 2900fps. The old berger data had a max of around 62 gr, if you get anywhere near 60grs the case capacity gets FULL. I have developed clickers after a couple reloads so aw2 on the way to fix it.

Decided to pass on the 568 since here and other forum stated it was slow. N565 turned out good velocity wise and SD wise. Gonna play with BTO and give N565 another go in a couple weeks.

143 ELD-X
2.340 BTO
New Lapua brass
CCI 200

Loaded 3 rds at the following:
56.g, 57g, 57.5g, 58g, 58.5g

Very slight ejector swipe at 58.5g. But I feel 59g is totally doable and will likely test it in a few weeks.

Here's the Garmin data for folks wondering.

Great numbers, I am right at 2950
With Berger 140 HT and 58 gr H1000 with a 24 inch barrel.

Sorry, old post, but what app is that? I'm assuming it comes with the Garmin Xero C1?

When N568 was getting ready to hit the shelves, the way I understood it, was it would be a short cut version of N570 which sounded great considering N570 generally produces some of the best velocities, BUT, because it's such a large bulky kernel size powder it mostly worked best in cartridges with larger case capacity and not so great in those with less capacity so the idea of a powder that produced great velocities like N570 often does but in a kernel size that would allow you to get enough of it in the smaller cases sounded awesome. Unfortunately, from the guys I've talked to who have tried N568 that hasn't been the case and it doesn't produce great of velocities at all.

In the 6.5 PRC H1000, N565, and RL26 have all been winners with RL26 often producing the best velocities but unless you already have some your chances of finding any are about the same as finding a Unicorn.

It's the gramin app and you can pair the chronograph with your phone and that's how it records the data and you can look at each shot string separately.
