Some Norma powder is becoming available, so I'm getting MRP, 217 and URP from MidwayUSA. Figured I'd better get what I could while I could.
Years ago I had great results with Norma 204 in my 7mm-08. No longer have that rifle, and have only a remnant of N-204 remaining. I understand from Norma promo that URP is similar to 204, with 10% TNT for increased energy. I guess that's like the Vv 500 series vs. the Vv 200 series.
MRP, reportedly is close to RL-22, maybe with less temp sensitivity and maybe more lot to lot consistency.
Not much out there on N-217. I'm thinking it must be close to RL-25. I have a 7RM that performs best with RL-25 and 168 VLD's/180 VLD's. Does anyone have N-217 loading data for the 7RM? I can't find anything on Norma's website.
Any thoughts/advice on these Norma powders?

I have used URP with good results in both 284 win and 7mm wsm. Seems to be similar to 4350.

My only experience with Norma MRP was a long time ago. I used it in 300 Weatherby. I used it because that is what Weatherby ammunition used from the Norma manufacture of their ammo. They actually had loading data using it. I was shooting my "normal" load that I shot all the time. It was in the summer. I had just shot 4 shots of an intended 5 shot string when a friend of mine came up to talk to me. I put the gun on safe and talked to him about 10 minutes. After he left I shot the fifth one. The recoil was significantly more. The cartridge had been sitting in the hot chamber. I had to hammer the bolt open because the brass had extruded in to the ejector hole. The Mark V action was fine. But that taught me a lesson on temperature effects. The barrel was not that hot. The load was about 98% of the listed max.
Gun Shows are almost as comical as boat ramps in the Spring.

I've had excellent performance with MRP in the 270, 280 & 33 Win.
It's fine grained & meters very will through a decent powder measure.

I use MRP in my 280AI, 7mm SAUM. 217 is the replacement for MRP2.
Enough already, just shoot it!

I was under the impression that 204 was identical to rl19.

Exactly.....and Norma 205 was changed(name)to MRP when H205 came out years ago.....I still have 10 or 12 pounds of Norma 205.
Luck....is the residue of design...

I heard from the famous "source close to Norma" that RL22 is MRP that does not make all the required specs. I have shot MRP for years, still shooting some I bought when a gunshot closed.

Bought 5lbs of MRP from Powder Valley about 6 weeks ago. So far it has shoot real good in my 270 winchester. 10 days ago I shoot a cow Elk on Camp Navajo with it and 150gr Nosler Partitions.

I ordered an 8# jug of MRP from MidwayUSA. That prorates the price per pound to $15. And, that stuff will last a long time.
Before the powder shortage, I had gotten powder ($700+ order) from Powder Valley, which is in Winfield, KS. My in-laws live in Wichita and I got my BIL to pick up the order. He lives in Derby, so it wasn't that far. When we visited Wichita last year, I got my powder without having to pay Haz Met or freight. Glad I did, as lot of what I bought is now very hard to find.
I was pleased to see Norma powder starting to show up on dealer shelves. I had never used MRP, but from what I understand, it's about like (or the same as) RL-22, which I like and use. RL-22 is my .300 Win Mag powder of choice. Although I have a couple of cans of RL-22, it's nice to have MRP back up.
