I have been hearing the praises of MRP for the 30/06 as the powder to use lately. I'm looking to hear of your experiences with it.
I primarily load 180 grain bullets for my '06 but am also looking at the Barnes TSX in 168 grain and for a heavy load maybe some 220 grain Partitions someday.
What do you all know about MRP?
Where are you all getting MRP?

Do a search. There are several posts over the last week or two about Norma powder being available.

I used MRP for years and ran out. I swithced to RL22 it is very very close. As is Winchester WXR.

All my MRP loads worked out to be 1 gr +/- in Rl22. Velocities within the accuracy of my Chrono. I doubt I go back.

Hey Ramrod I was reading one post that said they thought MRP and RL-22 were the same powder, another post said that MRP was less temperature sensative than RL-22. What is your experience in this matter?

isn't MRP the same thing as win 780?

Presumably, Norma MRP, RL-22, and WXR are all made by Bofors in Sweden and are all made to the same specifications. But remember, this powder is infamous for lot-to-lot variations, so just as one lot of, say, RL-22, may vary significantly from another, so will the various "brands" of this powder vary. All lots seem to perform fairly well, so whichever you buy, just be sure to buy enough of it to do everything you want for the forseeable future without having to start load work-up all over when switching to a new lot.

I used the Norma version many years ago with a .30-06/180 and it did exceedingly well.

30-06

IMR 4350 @ 56.0 w/180 Sierra GK
57.5 w/165 Sierra GK BTHP

Fed 210 Match Primer
WW Cases

This has been a outstanding load over the years!
These loads will work also with the Barnes TSX.

DITTO! If you need more speed in 30-06, try 150s with H414. 3000+f/s is easy, and a bit more if you work up.

My main load for my rifle is exactly like Alaska Bushman uses 180 gr Sierra and 56 gr of IMR-4350, mine is always in a WW case and CCI primers. I don't know what the speed is nor do I care but I was just going to experiment a little with this rifle as I have used that same load exclusively since 1987!
The rifle and load shoots 3 shot groups to an inch sometimes as big as an inch and a half but occasionally it gives up a sub one inch group. I just meant to play around a bit with 168-180 TSX's just to see and then thought I'd work up a 200 or 220 grain load, once again just to see how it likes them. I will probably always shoot my regular load unless something better comes along. I'd just been hearin about MRP and thought it sounded interesting.

Sorry I hadn't seen your question. I've never really had an issue with either. I've heard the comments about RL22. Since I live in Tx all my work is normally done in the HEAT. If the loads slow down I have never noticed.

My basic 30-06 load for the past twenty-five years has been 59 gr MRP ( I used to use Norma 205 till it was replaced by MRP) behind 200 gr Nosler Partitions. In my 22 inch bbl I get a little over 2700fps which has proven enough for anything I ever shot with it.
I liked the load well enough that I stocked up on both bullets and powder and until I started loading MRP in my 505 Gibbs I had a lifetime supply. I'm hording my last pound now for the 06.

Phil,

Black Hills Shooters Supply now has Norma MRP in stock.

I WILL SAY IT AGAIN....N MRP and R 22 are not the same powders...they are made by the same campany/under the same roof ...they are similar but not the same!!!
once collins finishes posting my pressure data ...another 15 spread sheets, i will test N MRP and R22 as far as temp sensitivity goes
it will be fired at 21 deg celcius...ambient temp then put in the oven and fired at a temp of 50 degrees cel and then fired after been in the cold at minus 20 deg cel
i will also test some 220 noslers and 240 gn woodleighs also, especially after phil shoemaker mentioned he nearly got them to expand to an inch diam....thats the woodleighs
after testing a varienty of diffrent powders NORMA MRP is the absolute ants pants so to speak for the 06 .....it takes the 06 up to another level above factory loaded ammunition, and also a lot of handloaded ammo with other powders

Hello Phil,
I recognized the combination of 458Win and 505Gibbs from your writing.

Good news about black Hills carrying MRP as I am interested in finding some good data for the 220 and 240 bullets as well. My son has been carrying an 06 with 220 solids in Zambia now for six months and says they are highly reguarded by PH's in that area for everything short of following up wounded beasts and they can even be pressed into service for that if the shooter is up to the task.

PHIL
what medium were you shooting those 240s into to get them to expand to an inch , geoff mcdonald had 100 buffulo shot with them in the territory while he was developing them and they seemed to do real well on the buffulo

I had hoped to use them this past bear season but the new, custom 30-06 I was planning to use them in was not 100% reliable in feeding so i did not get to use them on a big bear. I did fire them into wet snow banks, soaking stacks of magazines and alternating stacks of wet magazines with dry layers. In the wet snow and magazines the numerous petals spread out extreamly wide and the alternating layers of wet and dry tended to fold the petals back closer to the shank but they still were .60 caliber or better.
In fact you just reminded me; I think I still have some loaded ammo and will take it with me on my whitetail hunt next week.
