I remember reading on here where someone was using Power Pro 200mr when shooting these. My buddy is having a .223 being built for f/tr with a 30" krieger. It's been throated where the 90's are up past the neck/shoulder. I'll be doing load development for the gun and can't find the thread, anybody use this combo? Not much infor out there, I belive 28gr was max.

If you put 28 grains in there (it might fit) you won't have to worry about removing the primers. 
And I might suggest that you pull the trigger with a string.
I just finished doing my OCW load work with 2000MR and 90VLDs. I'm using LC and WCC brass with Tula 223M primers. I'm shooting out of a 28" 1:7 McGowan button rifled bull barrel mounted in a Savage target action.
You may get a little more velocity than I have with the 30" barrel. I got a node at about 2750FPS with 25.3 grains in 40 degree weather. I got heavy bolt lifts and got to 2900 at about 26± I should have taken a picture of the target, from 25 to 25.6 there was very little change in POI at 300 yards, at 25.9 the impact went up about 3 inches and at 26.1 it was up another 4.

I will be doing a ladder to test for pressure first XTR. Not just gona throw a max load in anything and "see what happens"
I'd start at about 24.7 or so and go up. If your rifle shoots like mine did the node is pretty apparent from 300 yards. I did a 6 load test. All the loads shot decent 3 shot groups, 24.7 was dead on my point of aim. Shot about a 1" group around a paster. The next three were about an inch to an inch to two inches higher, then the last two looked like they were climbing a hill. I shot all of my OCW tests jumping 30. Ive done enough testing in the past to know that I can jam this load so I'm doing seating depths next starting +10 into the lands.
I shot 90SMKs in the same test and they printed pretty much exactly the same POI and the same test shape only the node was .3 higher than the VLDs.
My rifle is throated out so I'm touching the lands at 2.070 to the datum line on a Hornady tool, my OAL is 2.650 to the lands.

I'll prob end up really close to what your seeing. I'm having the rifle throated so that the coal is 2.665. I'll do a ladder from 24.5-27.5 and watch for pressure. Thanks
Brad,
Cool another .223 on the line!
You may also want to consider using IMR 8208 XBR. I use it for the 80 SMK's and the Berger 90's. My current barrel is 30" 1:6.5 twist. It was throated for the for 80 SMK, so I have to load the 90's short. Shot high 190's with them when I took them out for a practice run. But loading so short, I had a little pressure signs showing. And you've seen how my rifles shoot, both .223 and .308 with this powder.
BTW- I never did get the 90's to shoot well with Varget.

I'm still working with mine. My load at 25.3 didn't work, and looking back the chrono kind of predicted it. I never pay a lot of attention to ES. I figure it's a cheap Beta Chrony and I let the target tell me what's going on, but in this case the data predicted the performance (not good) . I'm going up into the low 26s for the next test.
I looked back at some data from a guy who used to shoot the 90VLDs in a palma rifle here in Oak Ridge. His load with molyed 90VLDs seated with the bearing surface above the junction was 27.2, and as I recall he didn't have much for brass life. Shooting naked I think you're going to hit serious pressure issues in the high 26.* grains, and that's if you are seated out very long.

Here is a good read on the 90's in a .223. Fella said 27.7 with the molly's and 27.2 naked worked in his rifle for 2950fps.

The info is out there in bits and pieces if you're willing to search a bit. Here are a few links I found to be of interest:

I know the guy that was shooting the moly'd 90s. He was a member here in Oak Ridge until last yr. I also know he's left new Lapua brass on the line at Perry because he smoked the primers in one shot.
Yes, I believe his numbers that 27.2 worked for him with moly. He shot that load extremely well, but don't know what his brass life was. I think it was very short. I don't necessarily believe his MVs, and I don't know for certain that he ever got it really working at that load with nakeds. I know he was working on getting away from moly last yr but he was also building a 22BR and testing both. Some of his MV data he got based on come ups w/o good atmospheric info.
