N555, any experience with it

[bamban]

A friend gifted me a pound of it. Any experience with it? Load data for what cartridge?

 

[Eric H]

I have a 1lb but yet to use it. Supposed to be good for.6.5 CM. Go on their site for load data.

I ran a ladder test and OCW test with it in my 6.5 man bun and the 130 Berger OTM. Good speed, ES and SD, but best group was only .63" @100 yards. It isn't that I wasn't happy with that, but RL16 consistently groups in the .3s and .4s if I do my job. I suspect it may be better suited with heavier pills. I plan on testing it with the 156 Berger EOL when I get a chance.

Thinking about running it on 30-06 with 166 HH or 175 TMK

Good luck.

In my 30-06 with 215s I start to see pressure signs 1gr earlier with N555 than H4350 and the velocity was the same for both powders.

Chart I made from Quick Loads burn factors. Not all powders but ones that are used mostly.

Just beginning to work up a good all temperature load for a 30 Nosler and 180 gr Hammer Hunters. I got 3220 ft/sec with N555 at 95% load density with no pressure signs. Still doing the preliminary work with N555 along with N565, RL-23, and H4832sc.

Peterson brass, F215M primers, -0.050 off lands as a starting point, 24" barrel.

I have a couple of boxes of 180 HH, appreciate your input. Might start with the 180 HH and 555. I use N540 for the 137 HH, great velocity, well, the barrel is 28 inches long

 

[Rhovee]

It falls in between H4350 and H4831SC. Closer to SC.

I used N555 with 108 Bergers EH in a 6mm Creedmoor with great accuracy and velocity small rifle primers were FED-205M

Thank you for that. Saved, printed, and in my reloading binder.

I'm using it in a 6CM with good accuracy, and low SD and decent velocity. I am ok with slightly lower velocity, in hopes of extending barrel life a little.
I would recommend it.
Good luck

I'm using it in a 375 RBH (338nm improved and necked up). Pushing a 270 grain Shock Hammer @3k from a 22 inch 12 twist barrel.
Great es of 10 fps and outstanding accuracy
