I have a RRA DCM rifle, wilde chamber, 8 twist.  Have 69 gr SMK bullets and RL15 powder, federal match primers.

Anyone have a favorite load they care to share?  

Brass is cleaned, PP uniformed, flash holes debured, trimmed to length.  Just need to prime and load.

My range shoots 200 yd reduced

Here's some good info from White Oak...

just my 2 cents
i load rl15 at 24.9 cci small rifle primers with the 69 grain bullets

also 75 grain bullets here   ––-   rl15 24.7 cci small rifle primers  they are really nice as well and great at 200 and 300

my 69 grain load is as follows:

Lake City brass
sierra 69 match kings seated at mag length
winchester 748 24.0 grains
remington 7 1/2 small rifle primer.


i have cleaned 300 yard rapid prone targets with this load so these are MORE then accurate for your 200yards

Are the CCI pimers the small rifle or the military small rifle?

I use the Wolf SRM primers for everything. there are two, one for 5.56, and one a true Magnum. I use the 5.56 one. Harder cup takes the pressure better. With the same set up as you, the std CCI would almost always flatten. The mil primers or wolf ones never have.

I have used 3 loads for the 69's
25.3 varget
25.0 H4895
25.0-25.5 RE15

The varget worked good in the old barrel, but the H4895 worked better. The new barrel will shoot 69's incredibly well with the H4895 Load. as a reference my .223 M700 5R shot them into just under a half inch this morning at 200 yds. they will shoot under a minute in the AR, but damn thats about as tight as I can hold, sure they would shoot better if I could. The RE15 was just as good, but I save that powder for the 75's and the .308.
24.7 of RE15 mentioned by Randy is hard to beat. We figured out the same load here in GA would shoot in just about anything. If I had to pick one load for XTC that would be it. If your gun won't shoot it, rebarrel it. Its that predictable.

My other favorite loads for your set up are
77 sierra's
24.3 N140
80 Sierra's
25.5 N150, .015 off the lands ( no its not too slow)

Varget and RE15 loads with the 80's were blowing primers for me. even with mild or std loads. The N150 gives me 2820 fps and zero pressure issues. Also RE15 wasn't good for 77's I would get pressure just when they started shooting good, but N140 gave me more speed and better accuracy way before pressure issues ( right about 24.8-25.0)  and they were mild.


That 200 yd reduced MR-1 is nothin to f#@k with either.... Shot it once and it was the hardest target I ever shot.

USA SSG....

Sir, the 200yd reduced target for the slow fire prone stage of the match is the MR-52.  The aiming black is 11.79" diameter and the X and 10 ring are 1.79" and 3.79" diameter respectively.  If the shooter/rifle combination are not capable of MOA accuracy it will be very difficult to "clean" this target.  The same is true for the 100yd reduced target MR-31.  JMHO, 7zero1.

I have been using CCI reg small rifle for up to 75 grain bullets

Key point mentioned on primer
80s and 77s I use CCI magnum

I have used the mil spec 41 as well and they are great for this as the cup is harder
I work for a reloader loading and selling stuff  ––- we sell a lot of the mil spec both small and large

never had an issue for large but they do make them

never blown a primer using this method

Set up a 100 yd target, anyone of them, and shoot a 20 shot group into 1 inch slowfire, take your time, don't look int the scope to see where they went, just twenty shots slowfire for group with out looking. Do it on demand.  Harder than shooting a clean at 600.

The200 yd targt and the 100 yd reduced are smaler than actual moa size of the big one. they are tough.

yeah I learned this early on. justmade it simple and went with one primer for all loads. Do the same for the big bores as well.  Started pushing the 8mm hard and went to the magnums and ended up with better groups and less variences. Translated to every other cartridge I loaded too. Call me an athiest blasphemer but the Mag primers work well. even with precision rifle loads. .9 at 300 tds with a 308 and mag primers, who would have thunk it?? Although I  have blown primers with the 80's. Lapua brass may have bee as much to blame as anything, its just not that good in an AR for me.

But back on track, the 69 will be hard to beat in your set up at 200 yds. Very accurate. The varget and H4895 loads have worked the best, but with RE15 you should be able to use the Varget data without issue. I would recommend starting at 25.0, then trying 25.3 and 25.5 and see which one is the tightest, one will be obviously better than the other. With mag or mil primers of course.

Remington 7 1/2 primers will take the pressure too.

I used a scope on my rifle (flat top) and shot 1/2" groups at 100 yds using 24.8, and 25 gr of RL-15.

Loaded up 75 rds of the 24.8 load for our DCM match on Sunday.  Scored a 445 (personal high again)

1 FTF, but my fault.  I somehow loaded the case I used for setting up my trimmer (no primer).  It was during rapid prone, buty I cleared and had an extra nearby, still made time.

Loading bench will be clear of any other cases in the future.

I've also had some good results from 23.7 grains of Accurate 2520 and a CCI 41 primer in Winchester brass. My testing was done with a 20" barrel on a cold day (35F), but it's a light load for the 69 SMK, so should be no worries when the temps get back to normal.  Hopefully, it will still make the same ragged five shot hole it did in testing.

Lower left target...they are 3" circles at 100 yards (aiming black is 1"). Scoped Ar-15 from rest.  Don't know what happened with the "flier", but it's only a half MOA away from the group.

Rem 7-1/2
LC brass
Used this load in my RRA Service rifle.
Pretty warm load but shoots very well.

I've been working up a load for getting started in Highpower.  Powder of almost any kind has been so hard to get! My son and I - he shoots a lot of 9mm - kind of settled on Hodgdon H-322.  It works for both .223 and 9mmP.  I just tested some loads today working up through 20.5, 21, 21.5, 22, and 22.5 grains, and found that 21.5 grains of H-322 loaded under Sierra 69 grain Matchkings with CCI small rifle primers seemed to give best results from my el-cheapo 9-twist barrel.

So even though Varget is an extruded powder it meters ok or are you doing handloads? I may go that route instead of using the Dillon powder measure as the high power is not a volume reload. I cannot tell whether or not the Reloader 15 is ball or extruded.

RE-15 is an extruded powder.  Kind of short pieces, but my measure does "cut" some when I load.

LC Brass
Federal 205 MBR primer
24.7 RE-15

Shoots like a champ in both my RRA and Krieger barrels.

you know I bet if 20 of us got together and got 1 round from everyone else, we could all clean 200..... with 20 different loads. These are all good.

You know, you may be right.  

I chuckled at one of the stories I read about a guy handloading all his match ammo, carefully prepping his brass, uniforming primer pockets, flash hole deburred, weight sorting brass and bullets, weighing every charge, checking run out.  Shoots a great score at the match and his confidence was high.  Goes back to the car to put his stuff away and finds his ammo box still in the truck.  Realized he shot the "other" box which were all his culls with the off weight components and high runout rounds.  

Can't remember whose story it was Zediker's or someone else.

That is a Boots Obermeyer story.

Thank you, I either read it online or cited in someone's book.

do your own load start with the starting point and load from ther you will find a sweet combo from there rember don't change primers that you start with ,or seating depththat youstart with find your powder charge then you can change one vartable after that one at a time till you find waht you black loves to eat.

Sorry, missed this. I use an RCBS chargemaster. My mechanical powder measures won't throw varget very well.

When I uses this same load, and pretty much all my loads, I used a redding competition br thrower. No issues. That is a very good load BTW.

I mistakenly purchased Accurate 2230 for 200 yard matches, will this be alright to use with Nosler 69 gr bullets and Rem 7 1/2 primers? If so, how many grains of powder? The Accurate website does not list this bullet for that powder unfortunately.

Next time I will go with 2520.

I recently purchased 8lbs. of the new IMR 8208 XBR, that was touted to work well in all the calibers that I reload, such as 223, 6.8 spc, and 308 Win.  So I went to the range with my RRA NM, and worked my way up to a good accurate load using 69 gr. smk over the new IMR powder.  Prior to this load I have been using 24.5 grs. of Varget, but this stuff is shorter cut looking like H322.  It will not give screaming velocity, but it does seem to give consistent velocity and is supposed to be less affected by temperature, which to me is more important.

23.5 grains of IMR 8208 XBR (almost at max)

It works.  got a whole bunch on sale at Midway on one occaison.  I regularly use Varget and RE15 with my 69's, but the AA2230 was a good number.  I shoot in the sun a lot, and the ball powders can get a little crazy on warm days.  Nonetheless, the stuff is good. keep it out of direct sun and you will be gtg.

Thanks for the tip. I snagged 5# of RE-15 at the gun show last weekend so I will be using that now. The 2230 at 22.8 grains did fine, it was my shooting in the pouring rain that was bad.
