N555

N550 is supposedly a little faster burning (I've never used it). N555 is a little slower and powder charge weights are probably a little closer to h4831 in relation to when they hit pressure but is good in many of the same applications as h4350.

I'm looking in regards to 6mm creedmoor and 108s and 109s

For 6 creed I’d go a little slower than h4350 before I went the same or faster.

Hodgson Burn Rate Chart as of Nov '23 looks like N550 is the closest

I would go with n555 in your case. Very temp stable, accurate, good velocity. One of my favorite powders

N555 will work for you. Almost a full case before you'll find pressure. I've tested it directly against H4350. You might pick up just a little extra speed.

I’d have a tough time not just buying a keg of n160 for 300 bucks

In my burn rate chart, N150 is a little faster, N550 a bit slower. IMR 4350 would be a good one too and I've seen it available. A bit pricey, but I have seen it on shelves and I have used it forever.

N555 is your huckleberry. That's what I load behind 109s rather than h4350 and i've got 30-some pounds of h4350 on the shelf.

Also loading N555 under the 108's in a 6 Creed. I picked up a nice bump in velocity from H4350. 3050 FPS in Alpha brass and a 210m in a 22" currently.

Just looked and N555 is fairly new and not even in my burn rate chart. Looks to be a good choice. I think I need a new burn rate chart.

The 5xx series powders are double base. H4350 is not. That alone makes N5XX a bad substitute if you're looking for the exact same thing.
