I figured as much. I'll stick with N555.I tried it today. 56.9gn only got me 2757fps. N570 didn’t even crack 2750fps, but it did give me single digit SD’s and ES. Not saying much with only three shots.

RL16 is very promising, if you can find it.I figured as much. I'll stick with N555.
About the Roll Sizer, I had a long phone chat after several emails to the manufacturer as when I first saw it I thought that this would be the long awaited cure for loose primer pockets.I see what you’re saying. Yeah, brass life is important, especially when you’re trying to get enough reloads with the same brass for the barrel life.
I have been trying different brass. Lapua, ADG, and Peterson.
I haven’t gotten any clickers yet that I’ve noticed. I did see the fix to the issue, but not sure I’m willing to lay down the money for the tool just yet.
I will say my ADG hasn’t grown much, but the pockets are loosening up after only 4-5 firings. Only on the second firing of my Peterson and same with the Lapua. I haven’t shot much of the Lapua lately because I was getting good results on target with the ADG and Peterson.
54.8gn was giving me 2880fps with good results on target. If this brass doesn’t get me enough reloads, I may step back down to that on the next batch.

Universal Rollsizer
The Universal Rollsizer is an Adjustable Rollsizer capable of rollsizing all cases between 380ACP and 50BMG in one machine. Vernier accurate, high precision suited to low volume reloaders looking for the ultimate in accuracy. Your cases can be dialled in on the base to suit factory or custom...www.rollsizer.com
I agree RL 16 is good. I have some I am saving for my 6XC. I tried N550 in the XC but it was not as good as the RL 16.RL16 is very promising, if you can find it.
I still haven’t tried 4831 yet. That’s on my to do list.
Yeah, that’s what I heard. I grabbed enough for two barrels a while back.The issue I see with RL16 in the near future is if Alliant did suspend all powder sales for reloading purposes and will only be available to the ammo makers for the for seeable future....
I see only two sellers on GB that have any for sale. Your looking at basically $70 per pound.
Once you runout and can't find any what are you going to do then? That's the bummer part on some of this.
Keep your options open.
Most of it is already posted in this thread. Just back up a little. but I'll put it here for you as well on the H4831sc.Very curious on H4831sc, I know Frank has some results but waiting to see how it turns out for @CBTobias
I’ve been meaning to test 4831, but it might be a bit for me as I have 1086 rounds on my barrel and still have two comps left on the season. Maybe I’ll do a small quick test this weekend if I can find time to load up some rounds.A question, it seems that many are loading the 7PRCW/7-6.5PRC with the Berger 180 Hybrids & Triple nickel, I have a goodly supply of the 184‘s and lots of 4831sc and wondering if anyone is using this combination?
You are basically looking at a max charge of 58.0. I'd start under that some and work your way up. Both the 183's at 58.0 put it right at 65k psi and the 180 Bergers at 58.5 put it over 65k psi. I wouldn't expect anything different with the 184's.A question, it seems that many are loading the 7PRCW/7-6.5PRC with the Berger 180 Hybrids & Triple nickel, I have a goodly supply of the 184‘s and lots of 4831sc and wondering if anyone is using this combination?
What primer was used?I've got to load more ammo with RL16 powder. The ammo I sent down to Hornady for testing got lost in shipping.
They did shoot the other H4831sc ammo.... I'm just waiting on the data to be compiled and sent to me.
I wanted to attached some pic's of a fired case for everyone to look at.
I marked up one of the pictures and circled the ring that is left on the case from when it's fired and it pushes against the pressure transducer.
The last pic is of the primer. The firing pin hit looks funny but is normal. When the loads start hitting 60k and higher in the test receiver any little ridge from the firing pin hit gets smeared when the breech is opened. I think this pic is very important for everyone to look at. If you look at the primer it is not flat and nice round edges still. This ammo was running at 66k psi. The reason I'm showing this is a classic example why you hear... " just because you don't see a flat primer etc... doesn't mean the pressure is not running high/over the max etc.... it isn't always a tell tale sign of high pressure!"
Later, Frank

CCI 200's for all!What primer was used?
I ask because I'm helping a buddy learn to reload his own for 6.5 PRC.
While testing I was keeping an eye on his primers CCI200, nice round edges as well
