2000-MR Powder

[bigjohn451]

Ran across this powder at a gunshow this weekend, quick check of Alliants site listed it as a medium rifle powder with a secondary use for heavy bullet 223 loads. However they don't list any 223 loads, neither does anyone else so I figured I would see what I can do with it.

Disclaimer: The following information is backed up by NO published data, use it at your own risk. My gun is not your gun what may be safe in mine does NOT mean it's safe in yours.

Test gun: DPMS receivers, White Oak Armaments 18" SPR bbl.

Components for 1st test: New Winchester 223 Brass, Remington 7 1/2 Primer, primer uniformed and hole deburred, Hornady 75gr BTHP. OAL 2.260, lightly crimped.

I found reports on the powder listing it as similar to RL-15 so I used Hornady's listing of 24.1 as a base and reduced it 10% to 22.0. I loaded a single round of 22.0, 22.5, 23.0 to check for pressure signs, None noticed.

Groups of 3 rounds were then loaded and tested for preliminary groups:

23.5 .380 group
24.0 1.325 group
24.5 .810 group
25.0 .670 group

I stopped at 25.0 since it was a full grain over the base RL-15 data listed. No pressure signs were noted at anytime. Next round of testing will take it up a bit more to see where the max really is for my gun. Chonograph testing will follow once I get a new tripod to mount it on.

The accuracy makes it worth following up with further testing so will update this as I proceed.

Re: 2000-MR Powder

Thanks for posting, Just blindly loaded some up using the same barrel starting @ 23.0 and ending @ 24.0. Glad you had good luck with it.

Re: 2000-MR Powder

Just confirmed my loads yesterday at TVP.

Savage 10FP 308
Win case
CCI 200
175 SMK
47.2 gr 2000MR
Just under 1/2" 5 shot group at 100
2780fps
confirmed 32.75 moa to 1K

I have 0 pressure and plan to work up a load for 47.7 and 48.2 to see if they group as well.

Re: 2000-MR Powder

I went with 47.6 gr as center of accuracy node. This will give me a little flexibility on both sides and still stay in the sweet spot. Speed is cookin at over 2700 fps in a Rem 700PSS with factory barrel (24"). I have a bunch loaded up to test the best OAL this weekend.

Good stuff, Love how it meters.

Re: 2000-MR Powder

I just got my powder in yesterday. Unfortunately, I won't be able to get to any loading until next week or so. It's good to know that you all are getting promising data for me to use!

Re: 2000-MR Powder

I know this is an old post but looking for any updates. In particular, I would like some ideas on 2000MR with the Berger 80 VLD.
Alliant shows 25.1 max with the 80 SMK.

Getting the exact same #'s. Only have a 22" bartlein so to compensate I'm loading 47.9. No op. To be on at ftr matches only have to come 13.95 Moa

I have 0 pressure and plan to work up a load for 47.7 and 48.2 to see if they group as well. </div></div>

Re: 2000-MR Powder

I should be more informative I suppose. I thought the 80 grain bullet would give reason to believe I was talking about the 223 instead of the 308 I suppose.
I am looking for data for the 223 with 80VLD.
Thanks for the info there Aimsmall55.

Re: 2000-MR Powder

I couldn't get enough powder in the case to get the velocity I am getting out of Ramshot Tac which works really well for me. It does shoot pretty good though. 24.0gr with the 77gr Nosler gives me 2634 FPS average, about all I can get in the case with the 77gr bullet. I could get 25gr with the 80 Amax but velocity was still under 2700 FPS. I get 2870 FPS with Tac and the 80 Amax. This is in my 26" barreled space-gun. I get about 60 FPS slower in my A-2 Service Rifle with the same load.

Not trying to be a dick. It was I, after all, that forgot to relate that I was looking for 223 load data. Put your big boy pants on and chill out!

Holy Moly Guacamoley! I gotta try this stuff in my Rem 5r! It's like making a 308 into a "light Mag".

Re: 2000-MR Powder

I'm working with this powder in my 7-08 and 42-43grs looks to be real promising with the 162 Amax. Easy .5 moa.

Re: 2000-MR Powder

I worked up a load for my 20" TRG that pushes 200gr SGK at 2550. I do start to get a sticky bolt above 80 degrees. I use this load for temps less than 70 (which hunting in the am easily provides) and have the next lower accuracy load for higher temps or woods hunting.

I am also working up a load for 77gr SMKs in my AR. So far have found a very consistent, accurate load (10 rounds into 0.9 inches, most less than 0.5 inches) at a little over 2500fps. This load is similar velocity but more accurate than my RL-15 accuracy load. I need to find the next higher accuracy node and see what sort of velocity I get.

This powder also meters like water and is cheap!

If you could read the OP you would see that it was started with 223 in mind ASSHOLE!!!

Oh my gosh, your right. I can't believe I missed that. I guess I was just reading the OTHER 4 or 5 posts for .308. If I'm an asshole, then your my toilet. And all these other guys must be assholes as well

Re: 2000-MR Powder

Ok, there was data found showing 25.1 max charge with the 80 grain bullet. I ran my first OCW up to 25.7 grains. All thru the test everything was shooting well and into the same quadrant of the target. The 25.7 grain load showed not signs of over pressure and all five groups of three shots were very close in strike point and group size. I decided to see just where I could go from there so I loaded, at .1 intervals, from 25.6 to 26 grains. All rounds were similarly placed in respect to POA and all but 25.9 were nice and round (horizontal but I feel I shanked shot number two). At 26 grains I still saw no pressure signs (temp 52 degrees F). I did not gather any chrono data but I am going to load some more 26 gr loads and head back to the range with the chrono. I get target pics posted ASAP.

 

[shoot4fun]

Re: 2000-MR Powder

Follow up on 223 loads; I loaded more 80VLD Berger bullets with 26 grains 2000MR and headed to the range with my chrono. I felt no need to do the last step of OCW (test seating depth) as all loads shot incredibly well. I fired ten shots over my Oehler 35P. Accuracy was great as all ten found the same hole. Now, for the disappointment. This load is well over reloading data I found but served up a most disappointing 2855 FPS ten shot average. Yes, the SD was 7 FPS and I did say it was very accurate but this load is for 1000 yards and, compared to the AA2520 load I had previously worked up, misses the mark greatly. I chrono'd the AAA2520 load again with the same environmental conditions and found it making 2980 FPS (uses slightly less powder too). That 125 FPS is going to make a bunch of difference at longer distances. Oh, and the SD is 8 FPS.

Re: 2000-MR Powder

Did you see pressure signs at 26.0 gr.?

 

[shoot4fun]

Re: 2000-MR Powder

No signs of pressure but I think I am close to max. A friend is shooting 26.3 with moly.

 

[Belisarius]

Re: 2000-MR Powder

I asked, because my load with 80 SMK is a little heavier and the primers are not even flat. Stock R700 PSS 26" barrel mv-3050fps very accurate.

Pretty much. It has me curious as to how well it would push the 208 Amax.

 

[Belisarius]

Re: 2000-MR Powder

My test with 208 a-max was very, very limited. I used full length sized PPU brass/ what was I thinking/, I got 2670fps, 45.0 gr. 30" barrel.

Maybe I will try moving up by a tenth at the time to see what happens. I really like this powder. Meters great thru the Chargemaster. A little easier to work with than AA2520 IMHO.
Might also work up with CFE223.

Re: 2000-MR Powder

I just got 8lbs. (yes, it was in stock!) I gotta give this stuff a try. I have a stock Rem 5-R that shoots every load a lot slower than everyone else's rifle. It's accurate, but slow!
