Reloading data for 2000 MR?

[cpatbay]

I am looking at reloading data from Alliant web site for 2000 MR and could only find these for 168 gr and 175 gr 308 data.

308 Winchester Sierra 168 gr HPBT Federal 2.8 24 Fed 210 2000-MR 48.5 2,775 -
308 Winchester Sierra 175 gr HPBT Federal 2.8 24 Fed 210 2000-MR 47.7 2,720 -

What are these? Min or max? I guess Max?? If so, what is the Min? Alliant reloading site is not very useful ....

I am reloading for AR10. Thanks.

Those are max. 2000MR shoots best very near max, I get very good results with 47grs under the 168AMAX with lapua brass and 47.5grs under the 178HPBT with Win brass.

Since youre shooting an AR10 Id start around 46.5grs for the 168s if youre using Win brass, a bit less for Rem & Fed brass.
Ive always had good luck with 1 grain below max for autos, sometimes less than 1 grain from max.

I run 47.5 with 175 vlds out of a 22" Gap Crusader and get 2735 fps at 70 degrees. At 40 degrees I get 2703 fps. No op at all. Also run the 185 vlds at 47.0 with no op. Using lapua brass, fgm210m. I'm starting to believe this is the ultimate powder for the heavier bullets in .308.

Forgot to mention coal is 2.830, or 2.155 to ogive

These are great info, guys! Thanks!

Re: Reloading data for 2000 MR?

You will notice your primers will flatten much earlier in the charge range, mine did at least. So I just went off bolt lift/case markings for pressure signs.
All in Win brass, but bolt gun and a little longer than you will be loading to. Max, accurate/safe loads in my rifle:
168 berger hybrids, 51.5gn
185 berger, 49gn
200 berger hybrid, 47gn

ANYTIME you get a 175 up past 2650 fps you are looking at MAX loads. Since these are significantly above those MVs, it has to be a MAX load. If MR2000 has the characteristics of many of the other 175 SMK suitable powders, it will likely go crunch as the bullet is seated.

Re: Reloading data for 2000 MR?

I am somewhat confused. I thought 2000 MR was the end all be all for getting that extra velocity. But.... If it is taking 47+ grains of it to hit 2720 fps with a 175smk holy f'ing shit..... I get 2650 with 43.5 grains rl15 and I am not seeing the slightest bit of pressure

You do realize that 2000MR is a ball powder - very dense by nature.

I've used 46.5gn to get a B185 OTM going @ 2796fps from a 12 F/TR... and could still shake it like a maraca

Most loads with Varget or RE-15 that get similar velocity would have to be seated a hell of a lot longer and probably still be compressed or damn near.

Nope, neither of those is the case with 2000MR. I'm pushing 178gr Amax's to 2746fps and can still hear the powder moving in Winchester brass. I went all the way up to Alliant's listed MAX with absolutely zero pressure signs in my 700 Police.

What is your charge weight? Coal ? Only reason I'm asking is I'm pushing 175 vlds 47.5 at 2734 and 175 smks at 2770 with 48.0 I only have a 22" bartlein. My chamber is very tight ( Templar action) and my loads are compressed 2.830 is all I can fit in my AI mags but lands are 2.835 to 2.840. I wonder if the compressed loads with the tight chamber has any thing to do with the velocities I'm getting??

Yep, you are correct.

47.3gr 2000MR, 2.83", Winchester brass, Rem 9 1/2's fired from a 26" barrel

I still haven't nailed the load down yet, yesterday morning was the first time I've even fired the rifle, but it looks promising. I could probably pick up some more speed if it weren't for the cavernous throat Remington cuts into these guns, but the Amax's don't seem to mind the .100"+ jump that much

I bet they would absolutely scream from a 26" Krieger or Bartlein with a tight chamber though.

ETA: I tried 47.7gr as well, only picked up 12fps so I figured I was getting close to what was going to be my MAX. Granted, my load workup was in new brass, but every load I tried yesterday had an ES of 11fps or less.

51gn for berger 168 hybrids
48.6gn for 185BTLR
47gn for berger 200 hybrids. Shot my best group ever with this load but got a little gun shy after doing a "temperature" test, I shot these on a 90+F day and they were in the sun a few minutes, group opened up some kind of bad vertically.

These are all in a single shot savage FTR 30" barrel.

47gr for a 200 Hybrid sounds like a very hot load, how does your brass look? I run the 185 hybrid at 47.6 and my brass is fine but if I go a little higher im starting to get slight ejector marks. I know this powder likes to run on the hot side, at 47.6 im at 2800 ftps in warm weather (28 inch barrel) and driving tacks.

Re: Reloading data for 2000 MR?

I shot the 208 amax out of a 1:11.25 22" bartlein today with 43.2 at 165 yards. 2.107 to ogive. No op. 5 shots resulted in two itty bitty holes. Less than 1/4 moa. Fixing to run up in .2 increments to find what gives best velocity and my accuracy node w/ that velocity.

I used 48.0 gr. of 2000MR with 190 MK and it was fine, no signs of pressure, COL-3.000" 2880 fps in win brass

Re: Reloading data for 2000 MR?

Isn't MR2000 supposed to be almost identical to CFE223? Made in same plant, actually same powder but a little different or something?

Sorry, haven't been on here in awhile. It's probably a little hard on my brass, I'm getting about 4-5 reloads with Win brass before the primers are looser than I would like. Then again out of this lot, quite a few of the cases were unusable due to loose primer pockets.
OAL to ogive is 2.2685 @ .015" jump btw
