I did this for 6mm arc cases as well. I suggest anything you try, only do small batches to ensure you don't waste too much. Everyone seems to get wildly different results depending on their methods of sizing, annealing and loading. If you get too many splits, try changing things up, like...

Not saying It's impossible, but there is a significant amount of trimming involved in converting grendel to 6mm arc, I don't think it works going from arc to grendel. 6mm arc brass seems far more scarce anyway

I would think so. Verify a couple of your lots of powder against the table, it'll give you a better idea of what you're dealing with.

As long as you're going for ballpark generalities, it works. I've tried to do something similar for a different purpose. If you need accurate info, there's just too much variation between lots to trust it.

I still can't get them less than $96 per 1k after hazmat. Last time I saw any in a physical store, it was $8 for 100, limit of one pack.

I'm interested because I'm in a similar situation. I may be able to contribute, I have some loads to finish a work up on with CFE223. I had been working through some S&B srp, may even include them with the 400 and 41's. I'm focusing on the upper range, so I'm inclined to progress in tenth...

Unless I am misunderstanding, the primers were compared using the same established loads. Was anyone doing a work up that could have shown if the difference had pushed the load out of a node?

I haven't seen it myself, don't really have the range available, but would love to test it. Some people in the grendel community seemed to think something was there, making grendel brass from 7.62x39. Pure assumption on my part that it might translate over to the arc, if there is any truth to...

You can still get the 7.62x39 from starline at less than $100 for 250 pieces (cheaper than grendel brass), would be impressed if the factory ammo breaks down to anything close. Add in the large rifle primer option it gives you during a shortage, with potential accuracy benefits. I wouldn't...

You plan on measuring case capacity before and after? Do you intend to anneal before or after firing?

Brass and copper become brittle through work hardening (flexing or reshaping) . Exposure to high temperature can soften it, even to the point of failure. The higher the temperature, the less time it has to be exposed to it for this to happen. Aside from these 2, corrosion or more broadly...

How much did it end up costing?

Is there any particular reason to use grease type lubes over any of the common flavors of case lube we use for resizing? Is it simply too gummy to allow for proper cycling, or maybe more difficult to clean out of the chamber and action? I'm tempted to try this on the 7.62x39 I'm converting to...

I would've expected something like this to do some very bad things just from the hydraulic side of it. Guess it just goes to show how some things are simply not intuitive. Thank you for the explanation
