N500 Series High Energy Powder

Has anyone tried these N540,550 or 560 and what type of results did you get?

Re: N500 Series High Energy Powder

What chambering with what bullet weight? I use VV-540 in a .22BR and VV-550 in a .22-.243 Middlestead with good results.

N550 is similar to RL-15, a tick slower in velocity/pressure, accuracy is outstanding in the .308

Nighthawk, its not new but was told that it should give a 5-10% increase in velocity while retaining the same pressure.

S1 thanks it good to know what it compares to.

Re: N500 Series High Energy Powder

In the Highpower Competition world where I play, N540 has a good following when used with the .223 Rem. We're typically getting 100 to 200 fps more with 80 gr bullets than the other popular powders such as Re15, Varget and N140 (of course with excellent accuracy).

I was concerned that the greater velocity was coming at the price of dangerous pressures. However the proponents were not blowing primers. In fact their primers were normal in appearance all the way up the ladder (I'll stop short of quoting 80's velocities to avoid the skepticism that's sure to follow). I was sufficiently baffled that I ran some incrementally increasing charges through my strain gauge equipped AR Upper. The pressures I obtained were consistent with the primer appearance.

I've been told that the 500 series gives more velocity by Prolonging the Peak Pressures and thus increasing the AUC of the Time/Pressure curve.

One downside that was highlighted by a friend that was in charge of loading for one of the Military teams was that in their experience, double based powders such as the VV 500's were more temp sensitive.

I went with N540 last year in my AR after using N135 for years. It gives the same excellent accuracy with much better velocity. It makes a difference in a .223 at 5-600.
