My Sherman 6.5 max-600 yard ladder/group test

[odoylerules]

I think I've got a shooter here!
600 yards. 3" orange dot
21 inch barrel shooting Berger 156s with N570 powder
.015" off the lands

After this I was going to do a seating depth test

What's the vertical on the green and red groups? Those are the two nodes I'd focus on.

Those are some crazy speeds with a 156 and 21" barrel

Nice rifle and good shooting ! I'm noticing that all the groups are vertical but the red and purple are pretty much overlapping as far as elevation and velocity.

This is why i love this site! Learned 2 things from this post. I can use n570 in my 22" 6.5 max. And sandbags under the bipod. Thanks for posting!

The red is 1.75" and the green is 1.5" inches vertical

This thing is awesome! Very moderate recoil and carry's over 1500 lbs of KE at 800 yards

Yep, the recoil impulse can travel through the stock faster if you're on a hard surface with the bipods - especially on a stiff stock. I like shooting from the ground when going for long-range groups, but the sandbag idea is a good one. Will have to try that myself.

Man, that's excellent

I am just proud to see that you put the bolt on the correct side of the rifle. Neato spiffy keen setup you have there!

You will want to do an OCW test now on the Green and Red nodes. It would be interesting to see if you can replicate the ES and SD that you originally posted.

Pick the mid node to help with heat and cold temps. Nice shooting

Yeah, I am thinking 6.5 what? I notice that part is left out.
