Doing my part to #grownostr!

How do I clear the cache in Damus?

Um.

Wow. 🤯

VV is available (as much as any powders are available) pretty much anywhere. For the price check I went to Midway. VV is Finnish and a part of the Nammo group that includes Lapua and Berger. Flow is lately determined by granule shape and will vary with burn rate and composition. N555 has a uniform, squat, square cylinder shape that meters very consistently with my Lee Perfect powder measure. It uses wipers. I’ve been throwing charges well within half a grain.

This post is about VihtaVuori N555 but first, It’s odd to inadvertently find yourself as the top contributor to #reloading and #handloading. I hope I get other folks stoked on what they are doing to share their own progress and projects. What are y’all up to? What’s working? What’s cool? What sucks?

Ok. N555. My experience is still pretty limited but what I have so far, I like. I have had strings with extreme spreads (ES) in muzzle velocity (MV) of 5 feet per second! They were only 5 round strings during powder-charge testing but I’ve never had anything that low before. The load I’m using I have a 9-round string with 27.5 ES and 9.8 standard deviation (SD). That’s using an unremarkable, uncalibrated, beam balance. It’s not amazing but it’s plenty good for what I need. I’m hoping this next batch will be a little more consistent since I’m resizing the brass to be less loose in the chamber. I’m still full length sizing but I’m bumping shoulders back about 0.002” less than I did the last round. This could improve ignition consistency and I’m told by people with significant experience and impressive results that ignition consistency has a big impact on SDs and group size.

Back to N555.

The story is VihtaVuori developed N555 specifically for the 6.5 Creedmoor, what I’m shooting, and I’ve seen it picked up by multiple competitive (i.e. they often win) F-class shooters. What appealed to me about N555 mainly was its reputation for temperature insensitivity. I’m developing the load in moderate temperatures but expect to be using it in temps from 10-15° F. I don’t know how much that would impact a powder like IMR 4064 but I don’t want doubts running through my head while I’m taking a shot. I actually need the meat I’m hunting for.

VV says N555 has anti-fouling ingredients. I’ve not really pressed this with a high round count but the cleanup I’ve done after a range session has been noticeably faster than any of the previous loads I’ve used, both factory and my own.

Historically VihtaVuori powders have been a little more expensive and I was going to list cost as a downside but I just priced N555 against IMR 4064 and Reloader 16 and N555 is meaningfully less expensive!

The weird and unexpected thing about N555 is the cloud of smoke it produces. It’s definitely less than blackpowder but an old-timer at the range was wondering if it might be.

So, I’m very happy with N555 so far. I plan on buying it in 8 pound jugs. Not only do I save about 10% but that’s over 1,200 rounds from one lot number so I’m not wasting components and time verifying the safety and precision of a new lot of powder.

Do you have experience with N555 or other good powders for 6.5 Creedmoor?

I have not. The site isn’t polished but I’d risk $30 on it. It would be a pretty odd collection of items to scam people. I’d buy with a credit card.

Happy Sunday!!

I want to catch up with what I’ve been doing. I’ve been out to the range twice now! Not very much but when you have a real life and aren’t a gun toober you take what you can get and I’m stoked.

The first series are my load work ups (at 100 yards) for powder. I took it right to the max load of 41.7 of N555. The listed max MV (what I see as the true pressure indicator) is 2664 feet per second (FPS) and as you can see, I was getting about 2550 FPS. Tikkas are known for having slower barrels. I thought about chasing that extra velocity, but when I did the math, it didn’t get me very much difference in trajectory. I decided to stick with the max load at a safe velocity and that’s what you see in the last target with eight shots at 200 yards.

You can see the eight shot group is quite a bit wider than the same load at 100 yards. This isn’t just because it’s farther away, but also the barrel is light and as it heats up it begins pointing in different directions. I’m extremely happy with these results!

So what are you all up to? I can’t wait to hear from the other shooters what projects they’re working on.

I’d like to see a list of governments that don’t and then remove from that list the ones that can’t.

I’ve only found the loaded ammo, no bullets. ☹️ hopefully it will gain popularity and production. It looks like a great bullet!

Alright! Back at the bench. I’m now working up my final hunting load. I landed on VV N555 for powder (running a 6.5 creed) and Hornady ELD-X 143gr bullets. I know this gun will shoot these bullets well and I’ve seen them get the work done in the field but I have misgivings about them being cup-core bullets and not bonded.

What bonded precision bullets do you think are worth looking at? All I’ve found is Nosler Accubond.

This is powder development. I have just one round for each step working up to velocities I’d be interested in, then 5 rounds in 0.3 grain increments to max load.

I don’t have a great powder scale so I used my phone to remove parallax. I don’t know if it matters but I’m loading for precision (whatever I can get from a factory barrel) and I want to practice the best methods I know.

Next step: Finding time to go to the range! #whereswaldo
