I've used N555 with 130 Berger's and 140 Hornady ELDM's and it shoots well although I've got about 50fps less than H4350 for the 130's and that's using the Vihtivuroi listed maximum. I may push it a bit further since I saw no excessive pressure signs. It does fill the case more than H4350N555 or N550? Velocities don’t look great for N550.
Ran a quick velocity ladder with full length resized, virgin, small primer Starline brass and StaBall under a Berger 130gr AR Hybrid. The adjustable gas block was basically shut during this ladder, as I didn't want to beat up the gun as I went up in charge weight. No pressure signs on any of the brass, but I presume the bolt barely unlocking had a hand in that.
Thinking I'll load up 20 each at 44.6gr and 45.6gr to get the gas system up and running and see what groups and velocity data I can start collecting.

Anyone else played with the 130s and StaBall in a gasser yet?
When I ran the numbers at 1k it’s a difference of 14” from lowest to highest velocities from that string.More spread than I'd have. If I was you, I'd try berger 144 and 153's. ESPECIALLY with the cold ish powder your using
I completely understand. My youngest is 20When I ran the numbers at 1k it’s a difference of 14” from lowest to highest velocities from that string.
That’s acceptable for my current shooting needs. A 2yo eats up a lot of practice time and makes attending 3-5 matches a month a thing of the past. Current me is far less worried about winning than the old me and I’m just focused on trying to maintain some semblance of competency, haha.
FWIW I ran 50rds of the VihtaVuori N550 starting load with some 108 Scenars (38.3gns) and it worked fine; fed, cycled and no pressure signs. I can't really speak to the accuracy, except I did occasionally hit the 600yd lollipop.Anyone have any N550 loads? Thinking about giving this powder a try, since I can't find much H4350.
I am working on some 130gr RDF and StaBall 6.5 loads and getting mediocre results. I thought I would share and see if you had any recommendations as to how to get some better SDs with good velocity. Don't mind the group data too much as it was super windy and my target stand was moving and shaking a bit. Being shot from a 22in 1-8 barrel using Hornady brass and cci LR primers, sizing with a Redding Type S full length bushing die with .289 bushing ( I also have a .288). I have not seen any pressure signs as of yet so I am tempted to keep going up.
And on another subject has anyone had luck with the Hornady 140gr BTHP in a gasser?

I appreciate that as I have seen some of your data on them (sadly after purchasing). The problem is that I have 440 to use and only about 3 weeks to prep for a gas gun match. luckily the targets are generous in size and 90% will be 800yds or closer so even a 1-1.25 moa load will be ok. Any ideas/help will be greatly appreciated. And In the mean time I will continue my search for the 130 hybrids.First thing I would do.... ditch those 130 RDF's. Dead serious. I did extensive testing with them in both 6.5cm AR and 6.5x47L and they shot like shit for me in both SD's and accuracy... Thought something was up with my gun honestly they shot so bad. I ended up shooting some known loads with 130 Hybrids and one hole and SD's of 2.. Ditch them. I have had ZERO luck with them in 6.5 and .224......Im also not the only one if you dig up the 70 RDF and 130 RDF threads...

I am going to give it a try and extend the ladder test up to 46 in point .2 increments. Hopefully I see a flat spot. The case is still not totally full even at 46gr. I also have an AGB, no can though. I will hope fully be able to test them out tomorrow and report back.I'd keep going up into the 45.0+ range.
I found my sweet spot at 45.6gr with the 130gr Berger AR Hybrids.
No pressure signs on virgin/FLR'd Starline SP brass. This is also in a 22' barrel, but with a suppressor and AGB.
Got 32lbs of StaBall direct from Hodgdon a couple weeks back and will be testing another 20rds with the new batch of powder to ensure nothing is off before doing a big batch on the 650.

do you guys crimp your cases? I feel like my bullets get jammed being chambered.
