7 Sherman Max

[Harvey_NW]

Building a rifle during this reloading crisis made me switch gears from doing exactly what I might want to what's actually available right now, so I was able to secure dies and 200pcs of ADG brass for this build. Just wondering if anyone else is loading this round, and what kind of data is REALISTICALLY expected when using more common powders and not just relying on unicorn dust to obtain maximum velocities.

My setup will be a 26" CarbonSix barrel on a Defiance anTi XM with their BDL kit
I have Hybrid 110V, H4831SC, H1000, and IMR 8133 on hand
Hoping to launch 180 VLD, and possibly test 195 EOL

Need more info. What bullet weight? What powders do you have? What length is your barrel?

As much as we all love to hate on Facebook. Rich Sherman created a Facebook group specifically for his line of cartridges. He is frequently on there answering questions. Might be worth a look.

Was looking more for data actually gathered by people loading for this round, not guesses on what I will get. But for kicks, I will have a 26" CarbonSix barrel, I have Hybrid 110V, H4831, H1000, and IMR 8133 on hand, and will be starting with 180 VLD, possibly testing 195 EOL also.

I am on the page and look at it regularly, unfortunately I don't only want to run RL26 to achieve the highest velocity possible. That was sort of sarcastically noted in the post here, I'd like some real world data from guys that aren't only worried about appeasing someone.

Right, but how was anyone supposed to offer you valid data without knowing what components you would be using?

I have a bunch of load data for a 7 max in 140-155 gr pills using RL26. If you're shooting 180s and not using RL26 what good would my data be to you?

Ah, I'm tracking. Still just curious about data for any solid loads as well. Edited my OP.

What is your twist rate? Twist rate will determine whether you can stabilize 195's.

1:8

Depending on your altitude you should be able to run 195's. At what velocity I am unsure. There is not a whole lot of load data available that's for sure. There is one data load with 62.2gr h4831sc and 150gr smk. The other ones are rl23, rl26, n570.

Ask the FB group where they think younshould start. They will answer.
