7prc funny or not

the 3 and only listed powders for the 185 (only bullet nosler listed) are either discontinued or way past hard to find! so, what powders would be compatible for this (i don't have a 7prc)?

Look at 7 RM data. PRC is normally 2 or so less, in H20 case capacity.
Appears nosler didn't want to give much credit to the Public Relations Cartridge huh?

I would suggest you study the Hodgdon web site.
This isn't data specific to your Nosler 185, but the list of candidate powders will still be the same ones between these 180s and the 185s.

The advice above to also mirror the 7 RM data was the same idea. It would be a good starting point for candidate powders. Here is the list for 7 RM with 180s


Notice the similarities in the lists and the data? YMMV

The data for IMR7977 and H1000 are normally VERY close. The 7977 is slightly faster burning than H1000 IME. I've got all 3 of those powders but they won't last long, especially the speedster RE26.

H1000, N565, Retumbo, N568.

Those velocity numbers they are posting up are really low. They don't want to give the cartridge any promotion for sure.

Or VV powder it appears.

If you want info for a Hornady design cartridge, look at Hornady.
If you want info on a Nosler design cartridge, look at Nosler.
Would you go to Ford to find Chevy info.

In that case capacity, I find H1000 to be about as much case fill as the cartridge can handle, BUT, if you can get enough Retumbo in there, then that may be the best powder other than a double base Vhit powder.
I use H50BMG in those same size cartridges with success, 264WM, 270Bee, 257Bee & 6.5-300Bee come to mind. Have finished and threaded the 6.5-300Bee blank, so just waiting on headstamped cases.

Cheers.

My Son Cracked, the 3,000 FPS Barrier with, StaBall HD using ----- Grains of It and, the Hornady 180 gr ELD-M's !
But, has since, Backed Down to, the 2,987 FPS Level for, some, serious, Accuracy. ( Low 3's with, his Proof, 24" bbl on, a Tikka action )
He's Using MORE, StaBall HD than any chg's shown,. in the Hogdon Book so DON'T, ask !
ADG Cases, Mic OK and NO showing of, ejector Marks yet ! ( He kinda Knows,.. what, he's doing ).
Some Famous, Long Range, Elk hunter, gave Him, the Data

He have a 10tw?
Trying to figure out how his bullets reached the target...?

8 Twist, 24 inch, Proof barrel. 180 ELD-M's,. got to, 3,005 FPS.
Put 5 shot's into .314 Ctr to Ctr at, 103 yards, with the reduced Load, a few weeks back,. He's Happy !

Staball 6.5 is rumored to go from fine to too much all of a sudden. Which is OK, if you are careful, AND if it is truly temp stable.

I wonder where Staball HD will settle out. I have a 6.5-284 that I am trying it in. Using 6.5 PRC data as a starting point. I am going to shoot a complete one shot ladder from starting load to max, one shot every 0.5 gr and then stop if I hit any sign of pressure.

I shot the first couple rounds and had to stop (I had remounted the scope and had HOPED that my zero was not far off, but alas I was not papering at 100) so I need to move over to the pistol range and boresight and start over to get the scope on target.

I will say, the Staball HD was fast as hell already in my starting load. If this stuff is really temp stable and accurate, its going to be the replacement to RL-26 or even better. Emphasis on IF temp stable and accurate....... Might be like RL-33. That one faded away --- never got to shoot some.....

I've thought about the very slow powders (h50, 50bmg, rl50 & 2 vv powders), but so far for the 264wm I have rl33, 570, lrt to try. I do have 1 full # of 7977. I bought the 7977 for nosler 142ablr in 264wm.
