224 Valkyrie Reloading and Ammunition / Re: Primers Used
« on: February 02, 2019, 11:33:24 PM »
I'm using Federal 405M exclusively. Based on what others are saying, I'm thinking I might try the CCI 450's.

224 Valkyrie Reloading and Ammunition / Re: Berger 90grn. VLD's?
« on: February 02, 2019, 11:29:53 PM »
I haven't played the Berger 90's yet, but I have experimented with the 82gr LRBT-T. Not too much good to report there yet, best group was 1.2" @ 100yds with 25.5gr CFE223. I've got a test ladder loaded with Berger 75gr VLD-T's over Varget (23.5-25.5gr), but I haven't been able to shoot them yet. Too damn cold lately! I use Bergers with great success in my .243 Rem 700V.

Both Alaska_Guy and me did post on this. Here's a link to mine:

OPTION 1: You can use hot glue (correctable) or JB Weld (not usually correctable) to fill the end of the seating stem, and then push a bullet in very tight. Hold the seating stem open-end up in a vise. Build a jig to with wood or metal to be sure you push the bullet in straight. You can temporarily fasten this jig to your seating stem, or clamp it in the vise with the stem. IMPORTANT: Put a good release agent on the bullet, the outside of the seater stem, and the jig! When the glue or JB Weld is dry, just pop the bullet out and get rid of the excess material. Use as normal in your seater die. There are videos on line that show you how to do this.

OPTION 2: If you have RCBS dies, send three new bullets along with a check to RCBS in Oroville, CA and ask them to make a custom seater stem for you. Details are on the RCBS site (somewhat hidden...dig deep) or call them. I have custom seater stems like this for the 95 SMK and the 88 VLD-M. This is the better, but more costly, option.

I would just start with the 50gr data on the Hodgdon site and work my way up, watching for pressure signs. Pick a good light-bullet powder like Benchmark or 8208 XBR. Here's another tip: be sure to have some good copper fouling remover on hand! Lol!

Not only bullet weight, but bullet structure and speed affect stability. With these heavy .224" bullets, the faster you drive them the more stable they will be. I don't think you can over-stabilize any of the 80 gr and above bullets with the speeds capable of the Valkyrie. Somebody else can weigh in on that if they have better info.

Here's the factory Sierra quote on the 90 SMK: "Sierra recommends a 6.5” twist barrel for the #9290 22 cal 90 gr HPBT bullet when pushed at muzzle velocities lower than 2650 fps.  In cartridges like the Valkyrie with muzzle velocities above 2650 fps, a 1x7” twist barrel will stabilize the bullet correctly."

And for the 95 SMK, Sierra says flatly: "This bullet requires a barrel twist rate of 1x6.5” or faster."

Berger specifies a 7" twist for its 90 VLD Target, Hornady doesn't specify the twist rate for the 88 ELD-M in its online info. I Haven't checked the box.

All of that said, the above-mentioned bullets all stabilize nicely in my 6.7" twist barrel, as long as I keep the speed up with the 95's. I actually shot an 0.52" 100yd group the other day with the 95 SMK's flying at around 2550fps. I honestly don't think there would be a problem with the 95 SMK with a 7" twist. The bullet makers are notoriously conservative with their comments about performance.

For the most accurate reloads I highly recommend the RCBS Summit press (I have a couple of them) and the Forster Co-Ax. And sorry guys, I am old school... I weigh all my charges on a Lyman electronic scale. I'm not a progressive press guy.

224 Valkyrie Reloading and Ammunition / Re: Starline Brass
« on: January 05, 2019, 11:54:28 PM »
My Starline brass feels like the neck tension is a bit high but it measures .003". I'm not sure if that is considered high. That's one aspect of reloading that I haven't focused on much. If I remember correctly one rifle I was really trying to wring maximum accuracy by turning necks etc ( a 6.5x47 Lapua) landed at .001-.0015 neck tension ( difference in measurement of a sized neck before and after loading a bullet for non or new reloaders who might read this)
I'm using Redding dies btw.

Yup, I'm turning the necks now on all brass, but I've standardized on Starline for the Valkyrie. It does indeed reduce the neck tension (I'm using a Forster FL sizer), but it also makes the finished ammo more concentric. My loads can be as much as .005-.008" out of round without turning. With turning, they are all .002" or less with the same dies. Half of them barely move the dial gauge needle. I only take off just enough to make the neck consistent. You should see just a wee bit of "skip" somewhere in the turning pattern if you have the cutter set correctly. Of course, if you are using a mix different brands of brass, YMMV. And for sure, you can always set the cutter lower if you want less neck tension.

Woodbutcher, I suppose you found out by now that PP2000-MR soots up everything much worse than RL-17. Lol! But, hey, I get good results out of it.

I also have a sanders upper. But the 88s in mine touch at 2.325 so I loaded 2.290 to see how they do. Haven’t got to try them yet I may get out tomorrow

Interesting. What are you using to measure chamber depth? When I first loaded for this rifle I measured the throat to be a bit longer. Don't remember exactly what it was. When I loaded ammo to jump .02" using that measurement, they went into the lands and they wouldn't go into battery. Had to pry the bolt open, and sure enough, marks on the bullets showed they were into the lands. I switched to a Hornady OAL gauge, then I measured the throat with the 88's at 2.295" (avg.). Sanders doesn't give out the maker name of their barrels, so there's no way to know if we are looking at two different barrel manufacturers here, or what. Like I said, very interesting.

Well, I had a death in the family  :'( and was off line for a while, but I finally got to test the HDY 88gr  ELD-M / Alliant PP200-MR combo today. I used the top four recommended loads in Hornady's published data: 24.3 gr, 25.3gr, 26.4gr & 26.9gr. The 25.3 gr load was the clear winner in my rifle. It put 4 rounds into 0.315" @ 100 yards, but I had the inevitable flyer with the last shot that expanded the final group to 1.185". I swear the last shot jitters on a really good group is pretty much the same disease as deer fever. Lol! This load should give 2600fps in my rifle. Will chrono it at a later date.

The 24.3gr load was all over the place. 26.4gr was even worse, but with slight ejector marks. 26.9gr tightened up a bit, but worse ejector marks and some primer flattening.

Back in from the range. Testing the upper end of the scale of Power pro 2000MR.
25.3 = 2619fps .619moa
25.7 = 2640fps .893moa
26.0 = 2644fps .711moa
26.3 = 2674fps .510moa
I also ran some 760 at similar charge weights and have nothing to report there. Lapping the receiver
did not produce any noticeable gains in accuracy but it really runs like butter.

Very encouraging! I'm trying again after my initial disappointment. Paying more attention to precision, including bullet runout. I just loaded this test ladder for the 88 with PP2000MR last night: 24.3, 25.3, 26.4, 26.9. Hornady reports velocities of 2500, 2600, 2700, 2750 for these loads.

I loaded this set to 2.275" COAL / 1.710" CBTO, which is about an 0.02" jump in my 24"/1:6.7 barrel.

Will test next week, hoping for the best.

The lapping/polishing method works great in most instances. The problem is that it is not easily reversible. With the hot glue method you can use heat as an eraser, and change to a different bullet profile. Like I said, they both work well. But, with the Valkyrie being such a work in progress (for me), I really don't want to make anything permanent right now.

Long winded post to basically say this thing is a blast to shoot.

Alaska_guy, We are totally on the same page. You could have been writing that post about me! And, as you probably know, the "me factor" in shooting gets worse the older you get. I'll be 70 in December. When I'm shooting for groups I really wish I was 35 again!

Yeah, the Valkyrie is fun to shoot, but it is without a doubt the most difficult rifle to load for that I've ever owned. The previous holder of that title was a 45-70 Pedersoli Sharps that I shot in BPC competition. The Valkyrie is much worse, but so much more fun! BTW - I have a Timney Targa 2-stage trigger in my Valkyrie, and it is doing very well for me.

I would assume the groups wouldn't be much larger at 100 yards.

By the laws of mathematics, all other things aside, your groups at 100 yards will be twice as big in actual measurement on the target as your groups at 50 yards, i.e. 1" vs 1/2". However, the MOA will be the same at both ranges, as it would be for all ranges.

Having said that, we obviously can't ignore those other factors: scope precision, wind, seeing conditions, heat signature, etc. All of these conspire to make our groups even bigger at longer ranges than the expected mathematical size. Many times I have started on the 50yd range, and thought I found a good <1MOA load (<0.5"), only to move over to the 100 and see groups bigger than the expected 1.0".

I've been working on this. A couple of thoughts:

1. The presence of a ring indicates that the bullet has compressed somewhat, and "squirted" up into the seater stem. This is not just cosmetic. The biggest problem is that when bullet goes up farther into the seating stem than intended, the bullet will not be seated to the same depth as a bullet with no "ring". The cartridge base to ogive (CBTO) will be a bit longer on this round. If "ringing" is occurring, the CBTO's will vary because neck tension is never truly the same from case-to-case. Maybe when we get Lapua or Nosler brass for the 224V, but not now. If you are seating close to the lands the longer CBTO might allow the bullet to get forced into the lands when chambered. I've had a helluva time with this. There are ways to deal with the differences in CBTO, which I will not go into right now. Just be aware of this.

2. The hot glue trick works great for me, but it is not quite as hard in the seater stem than I would like. Alaska_guy, I really appreciate the JB Weld tip, I'll be trying that.

3. When you are doing this trick - no matter what you are filling the seater stem with - you really need to get the bullet in straight. I use a small piece of brass channel to accomplish this. I clamp the seater stem and the channel into a vise together, leaving enough channel above the seater plug opening to serve as a guide. When you are ready to push the bullte into the filler, just set it into the channel and push it down. (see photo)

4. I heat the seater stem a bit with a heat gun to help the hot glue to flow all the way into the seater plug opening. This would of course not be needed if usingJB Weld.

5. I use Super Lube as a release agent.

And yes, do clean the inside of the stem with a powerful degreaser to make sure the Hot Glue or the JB Weld sticks to it.
